Poswa verbs

Poswa verbs have 8 conjugation classes corresponding to the final letter of the stem of the verb. The commonest final vowel is /a/, so -a is considered the first conjugation class. Each verb also conjugates for three persons (1st, 2nd, 3rd) and three tenses: past, present, and imperative. The "plain" future tense is derived from the imperative. Verbal moods are handled by inflecting the conjugated verb (which always ends in a vowel) with consonants that resemble noun inflections. It could thus be said that verbs in Poswa are merely a subset of nouns. Lastly, each verb can be inflected for transitivity, so from each verb stem can be formed 54 forms.

The verb stem

The bare stem of a verb is rarely used in Poswa. Many verbs are highly irregular, but if one thinks of an alternate, "oblique" stem that replaces the primary stem, they become largely or entirely regular. Nevertheless, unlike in Pabappa, Poswa speakers cannot simply ignore the existence of the primary stem because it still does appear in certain constructions, such as indefinite serial verbs. Thus the verb stem can be thought of as an "indefinite" stem.

Another place where the bare stem comes into play is when infixes are placed into verb stems. Here, the verb stems that end in consonants are often changed into ones that end in vowels, or into ones that end in different consonants.

Forming verbs from nouns

Nominative

As above, the stem of a verb is considered a noun, although some verb stems are not used as nouns. When a noun is turned into a verb, the nominative case of that noun becomes the verb stem, and a list of rules governing vowel and consonant mutations is applied to derive the new verb forms, since for many noun shapes there is no regular form at all. (A few verbs are formed from other cases; these are described below.)

The most straightforward derivations are for nouns ending in -m or (in most cases) the vowels -e or -i, as the stems remain intact and the verbal suffixes are simply added onto the end. The meaning of the verb is often similar to the meaning of the instrumental case of the noun, despite being formed from the nominative:

Plinob₁ twembi.₂

I boated₂ home.₁

Where twem means "boat" and -bi is the 1st person past tense marker. (Verbs are not marked for number, so there is no separate 1st person plural marker.)

With most verb stems, however, the suffixation process is not so simple, and Poswa speakers need to learn a separate "oblique" stem that makes the process seem more intuitive. For example, poppup means "knife", but

Tašepi₁ poppipebi.₂

I cut₂ the apple.₁

shows a vowel change from -u- to -i-.

Accusative

The bare accusative form is rarely used to form new verbs in Poswa. When it is, it is generally an intransitive ad-hoc formation rather than an intention to form a semantically independent root. For example, a hunter being asked what he was hunting might say

Pruptafo.

I'm doing deer.

However, this is not common usage because there already exists a similar construction with one less morpheme, involving attaching the verb marker directly to the accusative form of the noun without the use of the "mutating" infix. Thus one would more commonly hear

Pruptapo.

I'm doing deer.

Accusative as reflexive

A second usage of the accusative form of the noun is to form reflexive verbs. Bupsapa means "shield", and the verb root bupsapap means "to shield oneself". This is similar to the -s affix, but whereas -s generally applies to plurals and carries the meaning "they [verb]ed each other", -p implies people acting only on their individual selves.

Causative

See Poswa_nouns#Causative. Not to be confused with #Causative verbs, which effect causation on the subject of the verb rather than the entity described by the verb stem.

The causative is not considered a true noun case in Poswa, but rather a subset of the accusative formed by taking the instrumental form of a noun and then inflecting that stem with the accusative. It is often identical with the ordinary accusative form of the noun and has bled some of its meaning towards the accusative. Nevertheless, it still retains many independent uses, such as producing verbs. These verbs are usually intransitive structurally, even if they have syntactic transitive meaning, such as

Fompwafo wave pabwepypup.

I'm making a mess for you to clean up.

Which is derived by declining fompa "mess" into its causative form, fompwap, and then adding the 1st person present verbal suffix -́o. (The accent above the dash indicates that it triggers mutation.)

However, the verb can be transitive if it describes action on another entity.

Fompwapabo pubupefep.

I'm making a mess of your bedroom.

Causatives with little or no change in meaning

Sometimes, a verb will alternate with its causative form with little difference in meaning; the intent is up to the speaker. For example, one can say

Pawab bullaedža babi rambasfaba.

The banana costs five pullabas.

Or, using the causative form,

Pawab bullaedža babi rambastwapaba.

The banana costs five pullabas.

The choice of which form to use is up to the speaker; the longer form does not indicate any additional emotion of the speaker.

Locative and dative

A few verbs are formed from the locative case of nouns. Both the literal sense of being in or at a place and the metaphorical sense of being affected with something are in common usage. Verbs of the former type are generally not listed in dictionaries because their precise meaning can be understood by simply knowing the meaning of the nouns from which they are derived. In most cases the same is true also of the metaphorical verbs, but there are some verbs whose exact meaning has diverged or is confined to a narrower range of meaning than those of the nouns they come from. For example, rumu and twu both mean "water", but one says

Rumombo.

I'm in the water.

But

Twombo.

I'm wet.

Becausative

The "becausative" construction refers to a verb resulting from a previous action or an entity taking some action. For example, pwembwa means "to aim", and pwembiam means "to shoot". The becausative is derived by adding the locative case to the essive case of a noun root, and for some nouns, it will be identical with the plain locative.

Pwembiambebi.

I shot you.

While there do exist examples of grammatically active, but syntactically passive verbs formed by using an -m-stem in this manner, it is more common to hear speakers instead use a true passive verb, which would use the nominative case stem to form the verb rather than the locative.

Verbal constructions replacing the dative case

Since pronouns are generally not used in Poswa, verbs have come to fill their role in certain constructions in which a dative construction, generally one using the #Becausative compound case, would be expected. This generally applies to people, since only people can be in the 1st or 2nd person. The commonest verb chosen is wava:

Tufo wavo blubutaenop bivambebel.

My husband cooked a meal for me. (It was quite a surprise!)

In some situations, a similar but longer verb, wampa, is used for the same purpose. Generally wampa refers to a situation in which the receiver of the action (the noun one would expect to be in the dative case) asked for the action rather than being a passive partner:

Tufo wampo blubutaenop bivambebel.

My husband cooked a meal for me. (I haven't been feeling well so I asked him to.)

A third verb, bae, is used for more mundane situations, generally impersonal ones, in which some other languages would use the genitive. For example, in a conference or classroom one might say:

Pwaepam apwa baebo.

The red chair is for me.

Possessive and reciprocal

The possessive case is not used to form verbs because it is identical with the reciprocal verb marker, -s. Here, reciprocal refers to verbs in which the (normally plural) subjects of the verb act on each other (not individually on themselves). However, some speakers may think of the two affixes as being the same, and saying that reciprocal verbs are "possessive verbs".

Reciprocal verb stems

Any verb can be made into a reciprocal verb, and it is considered part of Poswa's derivational morphonology rather than its inflectional morphology. That is to say, the stem of the verb changes to mark reciprocity, rather than an inflectional suffix added after the stem.

Instrumental

Food and drink

Names of whole foods and drinks are verbalized by adding suffixes to the instrumental case rather than the nominative. This is considered a type of subject incorporation even though the food is semantically the patient of the verb rather than the agent, and even though the verbs produced are not actually compounds because the instrumental case is a stem-changing infix rather than a separate morpheme. These verbs are indefinite, and are intransitive if the object is not specifically named. For example:

Pawiebo.

I'm eating a banana.

Levobampibo.

I'm eating strawberries.

Piebo.

I'm drinking wine.

Note that up above, the choice of how to translate the verbs into English was dependent on the meaning of the verb. Whereas most humans will eat only one banana at a time, strawberries are generally eaten in bunches. This is because these verbs are indefinite, seen as "general use" verbs, and therefore not marked for number. Thus, one would not use the plural suffix -bum in the middle of a verb and produce a word such as

*Levobampobiebo.

I'm eating (a bunch of) strawberries.

Here the plural infix is correctly changed from -bum to -bie- because of the inflection, but the word is still considered grammatically incorrect because this type of verb is generally indifferent to number.

All of the verbs above were intransitive because there was no explicit object named. If the object is explicitly named, the verb will be transitive:

Levobampobiepo levibo.

I'm eating the strawberries.

However, since the above sentence translates literally as something like "I strawberry-ate the strawberries", Poswob speakers would more often simply use one of its many verbs for eating that does not involve incorporation, such as

Levobampobiepi bavebi.

Levobampobiepi amnebebi.

I ate the strawberries.

Levobampobiepi biumbebi.

I ate the strawberries by actively pressing them against my teeth with my tongue.

Levobampobiepi pyparebi.

I ate the strawberries whole, using only my tongue and my lips.

Levobampobiepi vwambebi.

I ate the strawberries rapidly.

Levobampobiepi vabžebi.

Levobampobiepi možambebi.

I gobbled the strawberries with my mouth, without using my hands.

Levobampobiepi pirpafebi.

I ate the strawberries by nibbling them in small pieces.

(Here the verbs have been changed to past tense in order to give the speaker more time to digest the eight bowls of strawberries.)

Other foods

As above, whole foods and drinks are able to form indefinite verbs using the instrumental case of the noun stem. For foods, this use is restricted to fruits and vegetables. The Poswa word for chicken is tuppi, but one cannot say

*Tuppwabo.

I'm eating chicken.

The reason for this mismatch is because animals are not seen primarily as food products. In a room containing a human being and a banana, only one interaction between the two presents itself, but an interaction between a human and a farm animal can resolve in many possible ways. The choice of whether the verbal construction is permitted or not is determined by whether Poswa considers the noun to be both edible and an animate noun, rather than by strict biological criteria. Thus, small sessile sea animals are not considered animate and thus can be eaten in a single word.

Likewise, food products that have other purposes cannot be verbalized this way, such as

*Potibo.

I'm eating pine sap.

Beverages and other liquids

In the case of liquids, the same alternation produces an indefinite verb indicating drinking:

Blwibo.

I'm drinking milk.

Piabo.

I'm drinking wine.

Pippibo.

I'm drinking juice.

But not every liquid is considered potable:

*Porsybo.

I'm drinking blood.

*Potibo.

I'm drinking pine sap.

Oddly,

*Twibo.

I'm drinking water.

does not occur either. Twibo, formed from the instrumental form (twub) of the commonest word for water (twu), is avoided because it conflicts with the unrelated verb twub "to pee", formed from the nominative form of the word for urine. Thus, the sentence above actually means "I'm peeing!" Since the instrumental form of twub "urine" is also twub,

*Twibo.

I'm drinking urine.

Is also forbidden. If someone speaking Poswa wants to indicate that he is drinking water (or urine), he must use a traditional transitive construction with a separate noun and verb, such as:

Bwurabo twop.

I'm drinking water.

Note that this sentence is still ambiguous between whether it is water or urine that the speaker is drinking, but it is no longer ambiguous whether the speaker is sipping that liquid or pissing it. (See Poswa_irregular_nouns#twu.)

Use of the instrumental with articles of clothing

The instrumental base also describes the action of wearing clothes:

Plumpwibo.

I'm wearing a hat.

Essive

The essive case is rarely used to form verbs. When it is, it retains its basic meaning of indicating that one thing is made from another, such as:

Nobellam blwiba.

Icecream is made of milk.

However, since such verbs are almost always long-term general truths, Poswa prefers not to use verbs at all for such statements. The sentence above might subtly imply that icecream may not be made of milk next week. One would more often hear:

Nobellam blwi.

Ice cream is made of milk.

This sentence has no verb, so it is not distinguished from "ice cream (that is) made of milk", but this is how Poswa and most of its neighboring languages (but not Pabappa) express general truths.

Verbs formed from sentences

Subject-object-verb compounds

Some Poswa nouns are actually complete sentences with just the verb endings removed. This could be classified as a type of polysynthesis. Unlike the subject-verb compounds above, SOV compounds generally show transitive action, and are commonly used as verbs. However, because all verbs have a stem which behaves grammatically as a noun, they are nonetheless grouped with the other compounds as nouns. These can thus be called tripartite nouns.

Polysynthetic compounds are generally used metaphorically, with a different subject than might be expected from a literal reading of the morphemes in the compound.

Despite the description of the words as SOV compounds, all three elements are grammatically considered nouns and thus can take ordinary noun inflections. Thus, for example, the final element in the word for flea means "jumper", not merely "jump".

Many of these words are very old, and make use of short, sometimes even subsyllabic, morphemes that no longer have any independent use in Poswa as standalone words. For example, the early Poswa verb bi "to kill" has disappeared from the language as a standalone verb because it coalesced around 3000 years ago with a verb meaning "to lick". Poswob military generals soon had a difficult time winning battles, and many released their soldiers to devote time to more pleasurable pursuits. However, bi used with the meaning "to kill" is still found as the third element in some SOV compounds.

Structure of SOV compounds

Inanimate agents

The structure of SOV compounds is fixed to the SOV word order; they are not like the language as a whole where morphemes can trade places in order to emphasize one over another. Moreover, each of the three elements of the compound is a separate part of speech. However, when an inanimate entity is placed in the subject slot, its meaning is often syntactically passive; and when not, it implies an unmentioned animate agent. For example, wiwi "spear" appears in the subject slot of the verb wiršebbi "to fish (with spears)", but this construction implies an unmentioned human agent who is holding the spear he uses to fish.

Nevertheless, even these constructions follow the same basic pattern as the others, since a human catching fish with a spear can be said to "catch fish like a spear".

Active and passive nouns

SOV word formation is fairly complicated because each noun has separate forms for use as an active element and as a passive element. Generally these involve sound changes occuring in unstressed syllables (where the passive element usually is) but not in stressed syllables (where the active element always is, at least partly). Thus, the passive noun is generally shorter than the active noun, and is sometimes compressed into a subsyllabic element.

For example, the general purpose word for soap is mabem, and that is what it would be as an active element in a polysynthetic compound. However, as a passive element, it is vem because of a sound change that caused all mab[V] --> v[V] in unstressed syllables. Vowel shifts also occur; a common morpheme for "hand" is py when active but pi when passive. However, some words defy these rules because they were formed from rarely used words after those sound shifts had already taken place, and the speakers did not automatically apply the sound rules that "should have" taken place.

For example, one series of compounds is formed from pib "man" + yma "woman" plus a verb. This implies that the man is an active partner and the woman a passive partner in whichever activity is being referred to. The two morphemes cannot simply be switched to produce a word beginning with a stem such as *ymapib because pib means "man" only in the active position and yma means "woman" only in the passive position. Instead, the stem used to denote a woman acting upon a man is umaf-, formed from uma "woman" (active) and f(y) "man" (passive).

Active and passive sound shifts

Passive nouns undergo sound changes that do not affect active nouns. This is because they can only occur in unstressed position.

the /u --> y --> i --> e/ chain shift

A chain shift of /u/ --> /y/ --> /i/ --> /e/ affects passive nouns. The changes happened in the opposite order of the arrows, making it a pull chain rather than a push chain. Thus, for example, the noun pila "cohort, partner" appears as -pela- in some words where it is used as a passive noun. Examples of the other two changes are rarer because the vowel /y/ was rare to begin with and because when /u/ changed into /y/ that /y/ usually soon disappeared.

contraction of [V]b[V] sequences

[V]b[V] contracts by causing consonant mutation (for words where the first vowel is one of /a e i/) or labialization (for words where the first vowel is one of /o u y/) in passive nouns. This is, as above, because they are always unstressed.

Extraordinary shifts

Occasionally, an active noun will undergo some of the sound changes above assigned to passive nouns. This is because even SOV compounds can themselves be used as the second or higher-order element of a larger compound, and then later these contracted forms reinterpreted as standalone nouns. This has occurred sporadically with ordinary words, as well.

Accusative marking of passive elements

Note that the accusative ending -p on the object is often not present; this is because, if the passive partner is inanimate, the OV portion of the word can be parsed as an SV compound in which the inanimate subject is grammatically active but syntactically passive. However, if the passive partner in the compound is animate, it will take the -p.

Below is a table of some tripartite compounds found in Poswa. Parentheses indicate parts of morphemes that are alternately present or absent depending on the phonetic shape of the preceding element (even if a separate word).

Use of SOV compounds as verbs

Despite being described here as SOV compounds, these words are grammatically nouns so long as they are left uninflected. To use them as verbs, the typical verb inflections used in ordinary verbs must be applied.

Like all verbs, despite being syntactically transitive, the verbs are grammatically intransitive when used in a general sense with no explicit object. Thus one says

Wiršebbibo.

I'm fishing.

But

Džampapo wiršebbibabo.

I'm fishing for lampreys.

Babembabo.

I'm pulling your hair.

Note that the many words ending in -bana syncopate this to -bv- when forming their verbs, but the words ending in -wava change it only to -wav-.

Use of SOV compounds as nouns

These words are also used to form nouns. For example, the stem sušpen "to melt", plus the word šy "season", forms sušpenyš "spring".

Nested SOV compounds

Nested compounds are rare because most SOV compounds that are short enough to be convenient to use in a larger compound were created at a time when they were much longer. Thus, they would not have been able to use the words available at that time that have become very short in modern Poswa.

Nevertheless, some short morphemes are in common use in modern Poswa after all. Many of these are recent coinages that other languages would replace with abbreviations; for example plabas "hookworm" appears as pas in the words for hookworm treatments, and the sound changes that lead from plabas to pas are regular, and are part of Poswa's grammar, so they are familiar to all fluent speakers.

Nested SOV compounds nearly always place the inner compound in the object slot, thus creating an S(SOV)V compound. The inner word does not change its S component to use O morphemes even though by being infixed it becomes unstressed; the word is treated as an indivisible whole.

Sometimes, SOV compounds can appear the second element of a noun-noun compound. This is not considered to be a nested compound because it doesn't involve putting one word inside another. These compounds obey the same sound rules expected from other compounds, and depending on the age of the compound, may involve sandhi and syncope.

Modern SOV compounds

Modern compounding

Polysynthetic compounds consist largely of morphemes that have gone extinct in all other contexts because they have so many homophones. For example, the word bvwemi "to lather up" above was formed from morphemes that have become py + vem + i today. None of these words is used as a standalone form with the meanings they have in this compound. However, Poswobs know the meanings of these morphemes and do not generally need to look up the meanings of compounds like this in a dictionary unless they have become so compressed by sound changes that even the already sound-changed morphemes they are made of are no longer recognizable.

If the word above were remade with modern standalone morphemes whose meanings match those of the shorter morphemes above, it would produce a word such as pep + mabem + pwar ---> pemmabempwar. Thus, the use of otherwise obsolete morphemes continues in the modern language.

Choice of morphemes

The choice of morphemes in some of the words above may seem out of place even in a characteristically bluntly worded language like Poswa. For example, bwaptwup "rape" is made up of bwap "penis" and twup "to hurt someone" rather than being a euphemism. But this is partly explained by the fact that the morphemes used in words such as these are not used independently as standalone words of their own; the shortest unambiguous word for penis in modern Poswa is noppupu. Bwap is not in use as a standalone noun with any meaning except as the accusative case of bwa, a word for "store, shop, place of commerce" that is itself not normally used except as the final element of a compound describing which type of store is being spoken of.

Likewise, if it were re-created with modern standalone morphemes, the word bwammas "to impregnate, become a father" would be something like

Noppupurombapuspap.

Penis-womb-penetrates.

Verbless SOV compounds

Some SOV compounds are missing the verb. They are often called verb-absent compounds to point out that they are specifically missing a verb rather than simply being ordinary compounds of two nouns. These were mostly formed around 3000 years ago. Before this time, the sound changes necessary to make the word distinct from an ordinary compound of two nouns had not yet taken place; after this time, a change in the grammar made the use of verbs mandatory. Because the ability to create this type of word relied on a change in the grammar that happened after the split from Babakiam but before the modern stage, it is unique to Poswa; neither shared genetic heritage nor cultural osmosis allowed this feature to appear in neighboring languages.

Verb-absent compounds are able to express verblike compounds without a verb because the subject and object they use are such that only one verb is commonly used with such a pair, and can be implied without being stated. Thus, these compounds consist of two nouns. They are not confused for ordinary noun-noun compounds because the passive partner in the noun pair undergoes the same sound changes that it would in an SOV compound. Nevertheless, these compounds are rare and many speakers do not realize that they are even compounds.

E.g. "to man-woman "

OSV compounds

Poswa does not have true OSV compounds, but many SOV compounds have an inanimate noun as the first element, and an animate noun in the object slot. Since animates dominate inanimates no matter the word order, these compounds are treated as if they were ordinary SOV compounds.

However, they are more versatile in their OSV-like form than they would be in their ordinary SOV form. Thus for example one sees pupambam "rock for sitting on", not *papumbam, which is grammatical but unusual in that an inanimate noun is tied to the verb "sit" rather than the (inalienably) animate noun pa "buttocks, hips".

Often, OSV compounds are formed by adding a new element to the beginning of an existing SV or SOV compound. For example, taempom means "playground, play area for kids" and bempom means "den, nursery, play area for babies". But by adding the otherwise obsolete element rute to the beginning of each word, one can form new words: ruttaempom "children's toys", and rufempom "babies' toys". Rufempom is in fact the most common word for toys in general in modern Poswa, as rute fell out of use due to many of its inflected forms colliding with other words.

Note: how to express "sun hidden by moon"? Both are animate.

Note: tartempom , which has SOV word order, is more likely.

Morphemes fusing indefinite subjects and objects

A small number of morphemes in which indefinite subjects and indefinite objects have fused exist. These generally result from sound changes that occurred long ago, in some cases more than 6000 years ago, and thus were already thousands of years old when Poswa split off from Pabappa. They are relics of the even older species system found in the Gold language, which was preserved in its fully functional form only in the Andanese branch, which went extinct around 4500 years ago. However, before the species system died out from the Gold branch, it had begun to diverge somewhat from its original purpose and not all SO compounds are compounds of two species. Nevertheless, the commonest SO morpheme by far is

Fap

Human-human

Meaning that the word that follows the fap prefix is an action with a human agent and a human patient. This is a compound of ta, the nominative case of the original language's word for human, with tap, the accusative of that same word.

Person markers

Poswa marks the person of both the agent and the patient on the verb, but does not mark number, gender, or animacy. The number is often left entirely unspecified:

Bwabbu pofšap biumbebel.

The sheep ate the grass.

But sometimes may be inferred from context:

When direct specification is desired, suffixes are placed on the nouns to specifically indicate their number:

Pwopwa pisiam taesfa.

The child is sitting on the rock.

Pwopwabum pisiam taesfa.

The children are sitting on the rock.

Pwopwabum pisambiem taesfa.

The children are sitting on the rocks.

The gender of both the subject and the object is likewise inferred from context, and animacy is a property of each individual noun that speakers memorize as they learn the language (and it faithfully follows real-world semantics).

Verbs of possession

See also Poswa nouns#Possession.

Single-word sentences can indicate possession, because Poswa's formula for expressing possession is to put possession markers on its nouns, and those markers are etymologically related to the verbal markers. Thus, a noun marked for possession serves as both a noun and a verb, and there is no distinction between a word for "my cucumber" and a single-word sentence meaning "I have a cucumber".

Thus, Poswa does not have a verb corresponding to English "I have" or other equivalents such as Spanish tener. Whether physical possession or mere association is meant, the same simple construction is used: the noun being possessed is simply given a possessive marker whose person corresponds to the person of the owner.

Mio.

I have a bottle.

Pemmabo.

I have a seal (animal).

Pupsatabo.

I have a problem.

Bempuppo.

I have an arm.

A very small pool of irregular nouns exists, consisting mostly of kinship terms, in which the words do not end with the expected vowels, but rather change their entire stem to indicate their possessor:

Mama.

I have a mother.

Use of numbers after possessive verbs

Numbers are placed after the noun, rather than being part of it, although the agglutinative fusional markers are placed before the person marker:

Bomptšata nubesoffa bibi.

The mayor has four taxes.

Verbs indicating physical possession

Because of the convenience of the possessive constructions, verbs describing physical possession have narrow definitions and therefore do not always accurately translate English "to have".

Bul

One verb is bul, literally meaning "child, toddler", but dating from a time in the language when it referred to babies. Thus, to bul someone is not merely to have them but to carry them in the arms as one would carry a baby. Like other verbs, this can be applied to inanimate objects:

Bižebi twu blembiep.

I carried my water bottles.

Note that the stem change from bul as a noun to biž- as a verb is regular.

Pawa

Another verb describing physical contact is pawa, which is cognate to the word for banana, pawab. This implies a firm grip on an object, usually with the hands, more specific than mere possession. However it may be used metaphorically provided that the sense of an object being securely in one's possession is intended.

Babambwopo pawiabo.

I'm holding onto my stick.

Pawiabo palambol fubuwiop.

I'm keeping my voting rights.

Fatšam

For nonspecific monetary possession, the most common verb is fatšam, derived from the #becausative form of fap "to bend over". That is, someone who has bent over and picked an object up off the ground is likely to still own it. But it can be applied to larger possessions as well:

Fatšambabo wambžop.

I own my house.

Interaction with animacy

All Poswa nouns are either animate or inanimate. Poswa verbs can be conjugated as either transitive or intransitive. Inanimate nouns can only take the intransitive verbs; if an inanimate subject gets a transitive verb, it implies an understood subject, corresponding to the person marking on the verb.

For example, the sentence

Blaba žuftatiep rufaba

means not "Paper covers the floor" but "His paper covers the floor", which to many Poswobs would actually imply something like "He covers the floor with his paper". Pronouns are rarely used in Poswa except for explicit emphasis, as the person markings on the verb, and to a lesser extent the nouns, take care of the functions that in Pabappa and other languages are given to separate words.

Verbal tense

Past tense

Verbs are by tradition given with the past tense first, even though the present tense is more common. Its endings contain only the vowels /e/ and /i/. Intransitive endings have one syllable, and transitive endings have two syllables.

Rupwusebi žiašap.

I punched the screen.

Swi.

I slept.

Mapobum pembebiap pypembebel.

The girls held up their dolls.

Present tense

The present tense is the most commonly used tense in Poswa and Pabappa. Its endings are dominated by the vowel /a/.

Imperative tense

The third tense is not the future, but the imperative, used for issuing commands. Thus, there is no separate imperative mood in Poswa. Teachers sometimes refer to the imperative tense as "the future tense" for the sake of convenience, but there is a distinct formation that handles non-imperative future meanings. All six vowels can appear in various conjugated forms of the imperative tense.

Future tense

A non-imperative future tense can be formed by prefixing various words to a sentence that is otherwise in the imperative tense. It can be called the "future conditional" whenever the imperative is referred to simply as the "future".

Habitual tense

The habitual tense is rarely used in Poswa, as it has mostly merged with the present. Even in contexts where a distinction of meaning can be made, the proper grammar is to use the present tense in nearly all contexts. For example, this example sentence can have either of two meanings in English:

Luptempiop bworabo.

I drink orange juice. (Every morning!)

I'm drinking orange juice. (But only right now, because people are watching.)

Expressing tense and duration

Poswa uses the possessive -s rather than the locative -m to indicate that an action happened at a specific time. The word pybies means "while; during"; it is the possessive form of pybum "(period of) time".

Swi pybies, swaffi.

While I slept, I dreamt.

However, pybies is commonly seen in its contracted form, -pies, as a suffix on another noun, or occasionally a verb.

Swipies, swaffi.

While I slept, I dreamt.

With this suffix on, imperative verb forms take on the meanings of ordinary future verbs.

Bleppi wapwafipies.

Whistle while you work.

Additionally, imperatives ending in -b change it to an -r:

Bleppub wapwafurpies.

Let me whistle while I work.

Time words using -pies that contain fossil morphemes

This suffix also appears the word triplet

Pelpies, pappies, porpies.

In the past, in the present, (and) in the future.

Use of bare -s to indicate time

As above, the word pybies and its contracted form -pies are inflected forms of the word pybum "time". This inflection is a simple -s, and historically was used here as an extension of its primary function as a possessive affix. The bare -s can still be used with this meaning, but this construction is generally found when two verbs appear right next to each other, with no pause in speech. It could be compared to replacing English "while" with English "as":

Swis swaffi.

As I slept I dreamt.

Bleppi wapwafis.

Whistle as you work.

Use of bare -s to form concomitant verbs

The -s suffix can also be used to indicate that the subject of the sentence is performing more than one action, even if they are not taking place at the exact same time. In such a setup, all of the verbs in the sentence will take the suffix except for the last one mentioned. Thus, instead of all of the verbs rhyming perfectly, all will rhyme except the last one. This affix is optional, however, and invites comparisons to the English optional use of "and" in similar situations:

Pilabi, blovi, supši!

I came, I saw, I conquered!

Pilabis, blovis, supši.

I came and I saw and I conquered.

Adjectives and the habitual tense

Habitual tense in early Poswa

Early Poswa (Babakiam) had a fourth verb tense known as the habitual, which combined aspects of aspect and tense. The habitual did not have separate forms for past, present, and future, because it was considered a tense of its own rather than an aspect which could be conjugated for each of the three tenses. This is because of where on the verb it is marked. Thus, aspect markers could be used in the habitual tense.

The habitual was used for actions that were independent of time, often being eternal truths or statements of identity or equivalence. Many verbs in the habitual tense would be translated into languages such as English by adjectives rather than by verbs.

Habitual tense in modern Poswa

The habitual tense is no longer widely used for verbs in modern Poswa, as its forms have largely merged with the present tense. However, since no new habitual construction has been set up, this means that the present tense does double duty as both its original meaning and as a new habitual. Thus a sentence such as

Mapobum nobelliap subžviraba.

The girls are selling ice cream.

Can also mean

The girls sell ice cream (as a career).

This does not present a great problem for Poswobs because the predicate in the second sentence can be replaced with a noun, yielding a sentence such as

Mapobum nobellam pwamptae.

The girls are icecream sellers.

Habituals as adjectives

As above, the habitual tense is not included in the conjugation tables below. It can be formed by taking the present tense and replacing the vowels -o -ae -a by -y -e -a. Since nearly all adjectives in everyday speech are used to describe third person entities, there is no difference in most sentences between the habitual and the present tense. Nevertheless, the forms have not been analogized, and one can still say

Peppebe!

You're smart!

To remind the listener that they will still be smart tomorrow.

History of the tense system

In very early Bābākiam, infixes came to be placed within the habitual tense forms of the verb to derive the other tenses. These were redundant, since tense was already marked by a suffix, but the redundancy became frozen into the grammar and later sound changes made it less redundant.

Adjectives as intransitive habitual verbs

Poswa does not have a distinct part of speech corresponding to adjectives. Concepts expressed with adjectives in many other languages are expressed in Poswa partly by verbs and partly by nouns. Poswa has no copula verb, so a sentence can consist of just a noun and a verb playing the role of an adjective. These verbs are often in the habitual tense, which appears identical to the present tense. They always end with -a because the third person present tense of all verbs, even irregular ones, always ends in -a. The adjectival verb is almost always placed after the noun it modifies, since Poswa verbs almost always come after their subjects. For example:

Ipi pabbubufa.

The pine tree is tall.

Pepwep labbaša.

The knife is sharp.

Pompa mimptoba.

The thunder is loud.

Verbal adjectives do not change for number, because verbs in general do not have separate forms for singular and plural subjects. Thus one would say:

Ipibum pabbubufa.

The pine trees are tall.

Poppubum labbaša.

The knives are sharp.

And so on.

Sentences like the above can stand by themselves. (Note that inanimate objects can only take intransitive verbs.) However, verbal adjectives like the above can also stand before another verb:

Potwum wuvwaša žaefom pappwafa.

The blonde soldiers are marching on the bridge.

Comparative adjectives

Comparatives can be formed by verbal adjectives or by suffixes on the object being compared.

The dominant order is an unusual formation influenced by Moonshine, aopplying MS word order to Poswa structures: X Y-comp ad,.j

Men women-plus tall. That is, there is no wordf meaning "Taller" etc, just a word meaning "more than woman are".

Sabas paefampys pabbubufa.

The man is taller than the woman.

There is no separate form for the superlative; instead the comparative is used again with a word such as bomby "all, whole, entire".

The essive case may also be used here:

Sabas paefiel pabbubufa.

The man is taller than the woman.

Adjectives used in the role of nouns

One relic of the historical emergence of a new class of nouns from modifying verbs is that most verbs that are used with a lexically adjectival meaning can also function as nouns, be they transitive or intransitive. For example,

Bampfaba puvlwas pumwapwaba.

The one who hunts is running from a cougar.

This contrasts with a traditional noun setup, such as

Bampata puvlwas pumwapwaba.

The hunter is running from a cougar.

Words for colors

Words for colors in Poswa are formed with an infix, -ys-, on a noun characterizing the color being described. The parent language, Babakiam, used the same setup (although the infix was then -us-) for most of its color words, but it had also had a few "pure" color words that did not need an infix. Most of these have been analogized to the others in modern Poswa, meaning that today most color words are infix-based compounds. However, some of the most commonly used color words can still be used without the infix.

In many words, the infix loses its -s- due to sound rules or analogy with sound rules, meaning that all that is left is a -w- that labializes the preceding consonant. Thus the word for cherry is apa, and the word for red is apwa.

Thus, it could be said that Poswa has no basic color terms, only an infix that means "color of". Alternatively, it could be said that Poswa has a very large number of basic color terms, and that it is an open class, but that all of the color terms must have an infix of -w- or -ys- (allomorphs of each other).

A few words formed early on in the language took their infix and became color words, and then later on underwent sound changes and spawned a second color word. For example, papsa "white" and posa "pale pink; pastel pink" both come from a now-extinct word paba, which was one of the original pure color words that was not also the name of an object.

A weak but long-standing association between vowels and colors has led to the modern language preferring color terms whose vowels match the color being described. Red goes with a, which caused the word for cherry to be chosen over words for other fruits or other red objects such as blood.; yellow goes with i, yielding words such as bipsi "yellow" and bifis "blonde"; and blue goes with u, creating words like ubužža "light blue" and lumu "dark blue".

Color words can function as verbs or nouns, but when used to describe definite objects, generally take verbal endings even if the color being attributed to them is permanent:

Pablapwenam ubužžaba bymbežiam pyttaba.

The blue parrot is perched on the branch.

By contrast, one could say

Pablapwenambum ubužža raevapoleža prabio.

Blue parrots are my favorite color.

Becausative verbs

Poswa also uses becausative verbs. E.g. vwambebom "because I ate". This is essentially a conjugated verb with a noun case suffix on the end of it, as though it were an ordinary noun. The suffix used here is the simple locative suffix rather than the becausative, which is a compound of the essive case and the locative case. The forms are actually more regular and predictable than those of the ordinary conjugation, as the additional inflection smooths out some of the asymmetrical features present in the ordinary conjugation. Below is the conjugation of swavop "to dream" in the becausative formation:

	Agent	Patient	Past	Present	Imperative
Intransitive	1st person	—	swaffom	swaffom	swaffwom
	2nd person	—	swaffem	swaffem	swaffwem
	3rd person	—	swaffam	swaffam	swaffwam
Transitive	1st person	2nd person
		3rd person
	2nd person	1st person
		3rd person
	3rd person	1st person
		2nd person

Causative verbs

Poswa has an instrumental case which often describes the action of using an object to accomplish a goal. In a few words, there exists a "hard causative" formation which is not a true noun case, but is built from a historical compounding of the accusative ending on top of a word inflected with the instrumental case. These words, like accusatives, end in -p.

However, this setup only produces nouns, not verbs. Although these nouns can be used as verbs, they have specific, narrowly defined meanings rather than the dynamic meanings that verbs need to have. For example, poppup, a type of knife, is historically the causative form of a now-obsolete verb meaning "to cut", but one would not normally say

Tašepi poppipebi.

I cut the apple.

If they cut it using an apple corer. Rather, poppup has long been an independent word with a specific meaning referring to only that one type of knife. Instead, Poswa uses several different auxiliary verbs ("helper verbs") in serial constructions to indicate causation, as well as a few optional verb suffixes derived from previously existing infixes.

Causatives indicating permission and allowance

Imagine a boy (pypub) and a spaceship (pespol). The boy's mother will not let him fly the spaceship, but when she goes out for the evening and leaves her son in the care of a babysitter (wampata), the babysitter decides to let the boy take them both out for a cruise in the ship. Thus, the babysitter caused the boy to drive the spaceship, but did not force him to. The commonest serial verb setup here involves the use of the auxiliary verb bop before the primary verb. Note that the agent of the verb in this sentence is the boy, not the babysitter.

The order of the arguments in the sentence seems unusual to learners of Pabappa because it seems that the boy is doing the causation rather than the babysitter. It could perhaps, thus, be imagined that the verb bop means "to have permission to" and that the first noun mentioned in the sentence, the babysitter, is inflected with a possessive ending standing in for the now-lost "becausative" case of the parent language. The most narrow translation of sentences like this into English would use a passive verb, such as:

Wampafas, pypub pespep bofel masebel.

By his babysitter, the boy was allowed to fly the spaceship.

Note that wampata "babysitter" is inflected with the 3rd person possessive morpheme indicating that the girl is the boy's babysitter, but that on top of this inflection is added the genitive morpheme -s indicating that the boy is acting under her permission.

Because of the way the word wampafas is set off from the rest of the sentence, there is no change of meaning to the sentence if it is omitted entirely other than that the agent of the enabling of the boy is not named. Thus,

Pypub pespep bofel masebel.

The boy was allowed to fly the spaceship.

Is still a valid sentence.

Causatives indicating forced action

A similar setup is used to show that an action was forced by an outside power. In this case, the verb is nita.

Causatives indicating provoked action

Note to self: there is no verb free for this function right now, although either punu or pussap could work.

Causatives indicating help and assistance

For this shade of meaning, the helper verb is paepo.

Mapos, pypub pespep paepabel masebel.

By the girl, the boy was helped to fly the ship.

The girl helped the boy fly the ship.

Note again that the third person here refers to the boy, not the girl. Thus a sentence like

*Pypub pespep paepabi masebel.

I helped the boy fly the ship.

Is ungrammatical, as it would be in any other serial verb construction.

Aspect

Verbal aspect is expressed in Poswa in a variety of manners. Some use serial verb constructions, some use suffixes on the stem of the verb, and some use infixes that change the stem of the verb itself.

Iterative aspect

The iterative aspect is expressed through infixes on the root of the verb. Thus, verbs that end in a vowel will remain in the same conjugation with the use of this aspect marker. However, verbs that end in a consonant will switch to an oblique stem that ends in a vowel, usually the same as the vowel that occurs before the final consonant. Thus, the aspect marker may appear to be fusional despite the fact that they come before anything else and thus the forms of the verb in each aspect still always rhyme. For example, below is the conjugation of welwa "to pick (fruit); to pull something off a support" in the continuous ("default"; no infix) and iterative (-at-) aspects:

welwa Past Present Imperative Intransitive 1st person 2nd person 3rd person Transitive 1st person 2nd person 3rd person

welwata Past Present Imperative Intransitive 1st person 2nd person 3rd person Transitive 1st person 2nd person 3rd person

The difference can be used to show a difference in number, as below:

Apapi welwafabi.

I picked cherries.

Apapi weliabi.

I picked a cherry.

Other aspects

Continuative aspect

The continuative aspect can be expressed with the affix -(p)py-, which goes after the verb stem and before the tense/person marker. This is a regular sound-changed variant of the standalone verb prib "to remain, stay". This always becomes -(p)pw-, since all verb suffixes begin with -b-, and a sound rule causing -yb- to change to -w- kicks in:

Tšapompwo?

Am I still dripping?

For extra emphasis, it can also be expressed by adding wawepwob to the above. This word can be placed anywhere in the sentence, but is usually adjacent to the verb:

Wawepwob tšapompwo?

Am I really still dripping?

The forms of the continuative aspect overlap with those of the #Habilitative mood for verbs whose stems end in -m.

Resumptive aspect

The resumptive aspect is used to show that someone is resuming an activity. It can be expressed with either a serial verb construction or a suffix on the main verb.

In the serial verb setup, the morpheme involved is plym, which is generally used as an intransitive and conjugates with the same tense as the verb it modifies. Plym is a regular -y verb (the final -y is unwritten), and thus produces sentences like

Plymwi popabi.

I began to speak again.

When marking the resumptive aspect by using a suffix on the main verb, the morpheme is historically identical with the above but has undergone sound changes that have turned into -pim-. Here, too, there is a final -y that is unwritten in the Romanization, which means that this suffix automatically turns any verb it modifies into a regular -y verb:

Popopimwi.

I began to speak again.

Inchoative aspect

The inchoative aspect is used to express that someone is starting an activity, whether for the first time or as a resumption of previous activity. (See #Resumptive_aspect above.) This can be expressed either as a verbal affix or by way of a serial verb construction.

As a serial verb, the commonest verb in use is sublam. This is a regular -am verb, and is generally used intransitively.

Sublambo leššo.

I'm beginning to understand.

As an affix, the morpheme is -(š)wu-, a syncopated version of the standalone verb sapwu. Most speakers do not realize the connection between these two morphemes because both have changed greatly from their original forms. Nevertheless, the final vowel is intact, and therefore any verb with the suffix -(š)wu- will conjugate in the same manner as sapwu itself. Thus one can say:

Polapufopi pibišwebi.

I started to pet my cat.

However, due to sound rules, the -š- of -šwu- disappears or mutates after a verb whose stem ends in -m or -p, and may disappear after certain labialized consonants as well. Some examples of this is

Vupiopi pessampwebi.

I started to cuddle my boyfriend.

Puppasem pwapwi.

I started to walk on the pathway. (Note that this is an intransitive verb.)

For many verbs, the morpheme has shrunk so much that it has become difficult to hear, and in some cases, it actually has merged with the continuative aspect, which has a greatly different meaning. Additionally, it also merges in many forms with the #Habilitative mood marker, which is historically an independent verb whose stem got squeezed into just tw- over the years, which merges with -šwu- after verbs whose stems end in -m or -p.

Thus, speakers will often double up the marking of the inchoative aspect by using both this affix and a serial verb construction. Thus, sentences such as

Puppasem sublambi pwapwi.

which literally can be translated as

I started to begin to walk on the pathway.

Are in common use and are not generally seen as redundant.

Lastly, the inchoative aspect is often used when a resumptive meaning is intended. This is not seen as grammatically incorrect despite being ambiguous. Other times, a speaker will use the inchoative affix with the resumptive serial verb construction in order to indicate an intended resumptive meaning:

Plymwi popošwebi.

I began to speak again.

Cessative aspect

The cessative aspect is used to express that someone is stopping an activity. It can be expressed in several different ways. Like the others above, both serial verb constructions and a verbal affix are in common use.

Cessative aspect as a serial verb setup

As a serial verb the word is bum. Like other serial verb constructions, it is generally intransitive and bum matches the verb being modified in tense and person. Thus one would say

Bumbi bumpfapi bummafi.

I stopped kicking the chicken.

Note that the bumbi up above is at the beginning of the sentence, before even the object. This is more common with the cessative aspect serial verbs than with other serial verbs because the cessative aspect more strongly modifies the meaning of the verb than most other aspect markers do.

Cessative aspect as an affix

As an affix, the morpheme used for the cessative aspect is also bum, but this time it triggers stem changes in the words it modifies because Poswa has many historical sound changes involving morphemes beginning with -b and this morpheme has been used in this role for thousands of years. These sound changes are not the same as those that appear when one marks nouns with the plural suffix -bum because that particular -bum (which is unrelated) was a separate word, and therefore did not undergo sound changes, at the time that most of the involved sound changes occurred. Thus memorizing the rules for forming plurals is of little use in forming cessatives. There is therefore an entire table for each class of verbs.

Vowel stems

However, fortunately, the changes caused by -bum *do* line up with many consonant mutations that are triggered by forming verbs in general, differing only for verbs ending in -e, -i, and certain consonants. Furthermore, since -bum ends in an -m, it automatically makes all verbs to which it attaches into regular -m verbs. For example, from the verb stem taera "to run", one forms

Taebo.

I'm running.

This features a consonant mutation changing the -r- into -b- before adding the inflection vowel. The cessative version of this verb is

Taebumbo.

I just stopped running.

Which is intuitive and easily remembered. This example seemed more simple than most because it so happens that the mutated form of -r- is -b-, and -b- is the first consonant of -bum. Put another way, it could be said that the above word does not have -bum- as an infix but rather -umb-. However, this kind of misconception makes it more difficult for learners to use the appropriate forms because the -umb- analogy breaks down on many of the consonant-stem verbs. If one thinks instead of -bum- as a morpheme that triggers consonant mutation when attaching to a vowel-stem verb and then adds -(b)um, the rule never breaks down.

Likewise, from the verb stem pustila "to shake" one would form

Pustižabo.

I'm shaking you.

And the corresponding cessative form is

Pustižumbabo.

I've stopped shaking you.

Consonant stems

For verbs whose stems end in consonants, there are several other changes, all of which are found elsewhere in the language and not unique to -bum.

For verbs whose roots end in -s, the -s is deleted and, if an unstressed y remains as the final vowel in the word, a sound rule changing -yb- to -w- applies and thus the new verb stem ends in -wum. This is the same sound change found in noun plurals. This sound change also applies to the commonly used verb pys "to find", which lost its -s early on even in the standard present progressive aspect even though it was usually stressed. Thus one can say

Pwebi.

I found it.

But

Pwumbebi.

I stopped looking for them.

Because the serial verb morpheme and the affix morpheme are the same, cessatives are not "doubled up" for emphasis like many other verb markings are.

Use of the cessative imperative

The cessative is commonly used in the imperative, producing sentences such as "stop hitting me!" and the like. For the most part these differ from the indicatives in only a few phonemes. For example, from the above verb, one could form

Pustižumbybi!

Stop shaking me!

Although a common tendency is for this command to take a passive verb form, producing words such as

Pustižumbwub!

Stop shaking me!

This form is nominally one syllable shorter because a sound rule always triggers that changes the expected suffix *-byžub into -bwub. (However, strictly speaking this change is actually byžuby ---> bwuby, with the final -y's unwritten.)

Verbs with suppletive cessatives

Some verbs have suppletive cessatives. Often, these are used in the imperative or passive imperative. One common example is that popo "to speak, talk" changes to tšum in the cessative, respecting a now-lost stem tša. Thus one can hear

Tšumbwub!

Stop talking to me!

Shut up!

The tša stem originally meant "mouth", which means that tšum can also mean "to stop eating", corresponding to no single plain verb. Context makes the distinction clear, as one does not generally talk to a person while eating them.

Voice

Reciprocal voice

Verbal voice is marked primarily by changing the inflections. However, there are some lexical affixes that attach to the stem instead, and thus produce entirely new verbal roots. For example

Plabbži.

I danced.

contrasts with

Pop₁ plabblaši.₂

We₁ danced with each other.₂

where the reciprocal suffix -s attaches to the stem of the verb in order to convey the meaning "each other". This suffix generally pairs with intransitive verbs because its subject is also its object. This holds true even when the partners are separately named:

Pypub₁ wa₂ mapo₃ plabblašel.₄

The boy₁ and₂ the girl₃ danced together.₄

The verb can be made transitive in order to imply that while the two partners acted together, one was active and the other passive. This does not necessarily imply involuntary or forced action, but merely passive action. In this case, the passive partner must be placed into the accusative case:

Pypub₁ mapop₂ plabblašebel.₃

The boy₁ and the girl₂ danced together.₃ (He asked her to dance with him.)

Note that the -š- does not change to an echo consonant reduplicating the initial consonant of the root because it is derived from a palatalized -s rather than being original to the word.

Some verbs are used so often with the reciprocal voice that their original roots have nearly disappeared from use. For example, mušos "to play with each other" is common, but mušo "to play" by itself appears only in compounds, usually with sound changes, such as bempom "play room, den for babies".

Reflexive voice

The reflexive voice is marked by adding a -p to the stem of the verb. Using the example above, one could say

Pwopwaby₁ mušofel.₂

Each of the children₁ played by themselves.₂

Even though, as above, the bare verb mušo is not generally used, Poswobs are familiar enough with the -s/-p alternation to apply it to coin new words such as mušop "play by oneself".

Verbal mood

Poswa uses particles to mark most of its verbal moods. However, some are formed by fusionally inflecting the verb.

Indicative mood

The indicative mood is the default for all sentences and takes no marker, although, like most languages, emphasis can be added by using words such as "truly" and "clearly", generally at the beginning of the clause.

Interrogative mood

The interrogative mood is marked with question particles such as tus and pa, but is otherwise identical to the indicative, even in word order.

Imperative mood

The imperative mood is considered a tense in Poswa. See #Future tense.

Subjunctive mood

The subjunctive mood is formed, in every case, by adding -p to the inflected form of the verb. For those forms that end in consonants, the same regular sound changes that apply to nouns also apply here. Effectively the verbs are considered as nouns and the subjunctive mood marker is the same as the accusative case marker -p.

Since the vowels are the same on all of the tables above, it is only necessary to produce one table showing the subjunctive mood, as the endings here can be applied equally to all of the verbs in the tables above. The verb pwembwi "to shoot, to throw an object forcefully at a target" is used because there was no example of a verb ending in -i in the -e/-i table above.

INDICATIVE pwembwi Past Present Imperative Intransitive 1st person pwembwibi pwembwibo pwembwibub 2nd person pwembwibe pwembwibae pwembwibi 3rd person pwembwibel pwembwiba pwembwibob Transitive 1st person pwembwibebi pwembwibabo pwembwibbub 2nd person pwembwibebe pwembwibabae pwembwibbi 3rd person pwembwibebel pwembwibaba pwembwibbob

SUBJUNCTIVE pwembwi Past Present Imperative Intransitive 1st person pwembwibup pwembwibop pwembwibup 2nd person pwembwibep pwembwibaep pwembwibup 3rd person pwembwibep pwembwibap pwembwibop Transitive 1st person pwembwibebup pwembwibabop pwembwibbup 2nd person pwembwibebep pwembwibabaep pwembwibbup 3rd person pwembwibebep pwembwibabap pwembwibbop

Note that many forms merge in the subjunctive mood, and the use of pronouns or other words is sometimes necessary to keep the distinction. Whereas the merger between the 2nd person imperative and the 1st person past generally causes no trouble in indicative verbs, the three way merger between the various -bup forms can cause confusion in the subjunctive.

Desiderative mood

The desiderative mood is used to express wants and desires. Poswa handles this in several different ways, none of which are limited to expressing the feelings of the speaker. (This is why Poswob teachers do not consider this to be a true mood; rather, it is a means of expressing something that in some other languages would be a distinct mood.)

The easiest and most common method is to use a serial verb setup, usually with sase "to want, desire" at the beginning of the sentence and the predicate verb after it:

Puviopo papepwabo.

I'm burning my clothes.

Sasebo puviopo papepwabo.

I want to burn my clothes.

Note that the second verb is still in the indicative mood, not the subjunctive.

Usage of inflected nouns to express wants and desires

Sabas

Poswa can also use sabas, the possessive form of saba, an old word for "key". It can be used as a concise way to say "can I have a..." at a bar or restaurant. Since it is usually unstressed, it has undergone the sound change of sab ---> š before a vowel, which occurred only in unstressed syllables. Remarkably, it takes different forms for different persons:

Šos nobellam?

Can I have some ice cream?

Šes nobellam?

Can you have some icecream?

Šas nobellam?

Can they have some ice-cream?

However, it could be said that sabas is not a true mood marker because it does not generally occur with a verb. Note that these words are marked first with the "possessed" markers -o -e -a, which look like infixes because they are then capped with the final possessive marker -s.

Note, also, that saba and sabas are no longer used in a general sense to mean "key", as that word has been replaced with the longer word šalios, which has undergone the same sound change described up above by analogy with the unstressed auxiliary words.

The infix -ib-

Another method is to take a noun and add the infix -ib- to the last syllable of the noun. This infix mutates the last consonant in the word and has no other effect. Then, a possessive ending is added to the mutated noun. This is the same construction used to indicate "I have...".

The desiderative infix -ib- combined with the becausative compound noun case is always identical with the becausative formation itself, and therefore some becausatives have an implied additional sense of willful desire. For example, kas is an obsolete word for "to know", but it survives in the becausative form kašam "to ask (for knowledge)", because someone who wants to know something (the desiderative component) will, because of this desire, soon ask about it (the becausative component).

This formula, however, produces unpredictable results, since the same word could be expected to mean "because of (his) knowledge", and therefore is mostly found in older words that were coined before the desiderative becausative merged with the plain becausative. Most Poswobs are not aware of the etymology of many of these words, since the plain stems they derive from often have disappeared from the language.

Habilitative mood

This is used to present that the subjerct of that snentcence is able to do the verb,. Note that in Eng, many people say "I can hear you", etc, but in Poswa this would be a simple verb because "I hear" ad "Ican hear" are usually the same.

The most common method is to use an irregular verb, tos, either in a serial verb setup or as a compound. Tos also forms nouns, and is irregular there as well, thus giving it the distinction of being one of the few morphemes that appears on both the irregular verbs list and the irregular nouns list.

Expressing "to try, attempt"

The act of attempting to do something, without reference to its success or failure, can be expressed by a serial verb setup involving the primary verb fipaema followed by the verb being attempted. Usually, the two verbs are placed directly together rather than being separated by the object of the verb. Thus one can say

Fipaevi babribi lupponwap.

I tried to hide the body.

An alternative method is to use the verbal affix -misi- between the verb stem and the inflection. This turns any verb it modifies into a regular verb:

Babrimisibi lupponwap.

I tried to hide the body.

A small number of verbs have developed fusional forms of this affix, generally involving deletion of the first -i-, which triggers other further sound changes. For example, the very common verb pys "to find" combines with misi to form the verb pimpi "to search for; to try to find something". This is a regular -i-stem verb, producing sentences such as

Pimpibabo paffamios.

I'm searching for my medicine.

Some such verbs are derived from stems that are otherwise obsolete. For example, the obsolete verb stem *wiš- "to learn, be taught" is the base for the modern verb wišympi- "to study", but does not generally occur without the affix even in other compounds.

Note that the deletion of the first -i- in -misi- can only occur when it follows a verb root ending in a vowel. Although there are some examples deep in the history of the language whereby an initial -m- in an affix drops out, which could then trigger the -i- to drop as well, the use of the affix -misi- only came into play long after this sound change had stopped operating. The reason pys was able to undergo the change is that there was a separate sound rule deleting -s before a voiced consonant, thus producing the shorter stem py-. This rule itself, however, is no longer operative.

Lexical derivations involving fusional suffixed -misi-

Below is a table of verbs with various permutations of the affix -misi-. Words where the affix simply remains misi are not listed here, since their meaning never diverges greatly from what would be expected from the meaning of the verb stem itself. Verb roots marked with an asterisk are those that are no longer commonly seen in isolation:

Verb	meaning	Derivation	meaning
pys	to find	pimpi	to search for
*wiš	to learn	wišympi	to study
sys	to sleep	simpi	to try to sleep
*pes	to cut in two, to divide	pempe	to try to cut something in half; to pull on an object at both ends in order to break it
bavba	to injure, harm	bavbampe	to attack
*wapa	to push down	wapampe	to compete, try to win
*mwu	to measure	mwumpe	to estimate
mi	to see	mimpi	to try to see, look carefully
*wa	to eat	wampe	to try to eat, avoid vomiting
šiši	to smile; to laugh	šišimpi	to try to smile; to pretend not to feel pain
pupa	to avoid; to shy away	pupampe	to try to avoid something; to deny reality
pwas	to squeeze; to give birth	pwampe	to feel labor contractions

Some examples of these verbs in use are below:

Wapampebabo.

I'm competing against you.

Papwopwapi bavbampebebi.

I attacked the dog.

Pubvwo. Wampebo.

I'm sick. I'm trying to keep from throwing up.

Pfwupfwepapub nabbub. Simpibabo!

Turn off the light. I'm trying to sleep!

Some words show little change in meaning when the affix is added, except to indicate the speaker's uncertainty of the fruitfulness of the action being taken. But some verbs of this type have nevertheless taken on a fusional form of the affix rather than simply using -misi:

Bampampebabo.

I'm trying to hunt.

I'm hunting.

Verbs indicating successful actions

The infix -ep- can be inserted into the final syllable of the root of any verb to emphasize that it describes a successful action. This is an infix, not an affix, so it resembles the aspect markers such as -at- more than it resembles most other mood markers. This infix is rare, since most actions spoken of are generally assumed to have been completed successfully, but it can be used in order to give emphasis when the listener is in doubt.

A few verbs have irregular or suppletive forms for this particular inflection, generally verbs whose stems end in consonants and therefore have a separate oblique form that appears when infixes are placed within them. Thus, it is not anything unique to the infix -ep- that triggers the alternative forms, but rather, these verbs share a single oblique form for all such infixes. For example, using the irregular verb pys "to find", one can say:

Ipae, puntatšopi pipepwebi.

Yes, I've really found my marbles.

Lastly, the -ep- infix can be used to show that an action was done on purpose rather than being involuntary.

Ipae, pumblepwebi.

Yes, I laughed at you on purpose.

Verbs indicating unsuccessful actions

The most common way to indicate an unsuccessful action is to take the subjunctive form of the verb and add a second verb, ta, to it. The verb ta is not used by itself, but carries the meaning "to fail, to try unsuccessfully".

Subjunctive

Because all subjunctives of all verbs end in -p, and because there exists a sound rule automatically changing any unaccented -pt- to -p-, and lastly because all verbs ending in -a lose the -a in their conjugations, the "unsuccessful" suffix appears to consist of a simple verbal ending attached to the subjunctive form of the verb being described. This construction came into use only in slow steps, because in its original form, it was four morphemes long (two for the inner verb marker, one for ta, and one for the outer verb marker). Below is the conjugation of pwembwa "to shoot" conjugated with the suffixed verb ta "to fail":

NOTE. THE TABLE BELOW IS PROBABLY WRONG BUT I CANT CEONCENTRATE RIGHT NOW. E.G. 'WIO WIE WIA' IS FOR SURE WRONG BECAUSE THESE ALL CHANGE TO W-LESS FORMS.

	Agent	Patient	Past	Present	Imperative
Intransitive	1st person	—	pwembwiupi	pwembwiopo	pwembwiupub
	2nd person	—	pwembwiepe	pwembwiaepae	pwembwiupi
	3rd person	—	pwembwiepel	pwembwiapa	pwembwiopob
Transitive	1st person	2nd person	pwembwiebupi	pwembwiabopo	pwembwibupub
		3rd person
	2nd person	1st person	pwembwiebepe	pwembwiabaepae	pwembwibupi
		3rd person
	3rd person	1st person	pwembwiebepel	pwembwiabapa	pwembwibopob
		2nd person

This creates sentences such as

Pubbabumbapi pwembwiebupi.

I tried to shoot the duck (but I missed).

Since the subjunctive forms of all verbs and the accusative forms of all nouns both end in -p, in sentences like this where the object is placed first and the verb second, the two words will rhyme.

Infix

A less common method of expressing unsuccessful actions is to use the accusative form of the noun root that inhabits the verb stem followed by the same suffix ta. This was the original method, and more closely resembles the setups that Poswa uses for other similar functions. However, due to the same sound change described above, for many verb stems, this particular inflection coalesces with other forms of the same verb, or with other forms of other verbs. In general, verbs that end in vowels can "safely" use this form of the verb since the result will be a suffix such as -po, as the -p that marks the accusative is protected from being changed to -f- by the fact that it was followed by a -t- at the time the sound change of p ---> f occurred. Verbs that end in a consonant will change to their oblique form and then add that same suffix, with the -p again protected by the disappearing -t-. Nevertheless, this method of expressing unsuccessful action is found mostly in certain commonly used verbs and not as an ad-hoc formation such as the duck hunting example above. One common example of use of this verb is

Pipopi.

I couldn't find (it).

This is formed from pip, the oblique form of the verb pys "to find", changed into its accusative form (pip carries an underlying suffix -o), plus the verb stem ta "to fail", which disappears entirely from the resulting final word form, plus the 1st person past tense suffix -i.

Essentially the difference between the two formations is that the subjunctive method leads to repeated verbal endings, since the verbal endings are expressed both on the main verb and on the suffix that carries with it the meaning "to fail". This makes this method the only possible method to use when one wants to express person-changing verbs such as "I failed to make you learn."

Sometimes, the two infixes are used together, to form a symmetry. The affirmative formation is often used in response to a negative question, such as

Pipope, pa?

You couldn't find anything, right?

Pupae, pipepebi!

No, I found them!

Serial verbs

However, often speakers will use a serial verb setup such as žaepsa before the verb.

Other moods

Nouns can form mood markers of unusual types that are difficult to describe. For example, the word "please" is generally translated as pwaewam, and used as a prefix to the rest of the sentence. Pwaewam is the locative case of pwaewa "charity, favor, good deed". This is in contrast to languages such as Khulls where "please" was actually a fusional inflection on the verb.

Negative verbs

Verbal negation is accomplished in several ways, and in most cases, a Poswa sentences with a negative verb will use more than one type of negation on that verb. That is to say, it has redundancy, the same way Poswa verbs often have two or even three tense markers on.

The affix pep

Most verbs can be negated by adding the affix pep, which also functions as a standalone verb meaning "false; to be false":

Pabblombebi.

I whistled at you.

Pabblompepebi.

I didn't whistle at you.

If the verb to which -pep is added is irregular, it becomes a regular verb that follows the expected conjugation patterns for verbs ending in -p:

Pappwebi.

I bit you.

Pappopepebi.

I didn't bite you.

Note that the irregular verb pappo "bite", whose transitive oblique stem is pappw-, becomes regular again when the affix -pep is added. (This verb borrowed most of its conjugation from a previously existing verb pappop "to chew", but the negative form is pappopepebi and not *pappoppepebi because of a sound rule simplifying the second of two consecutive geminates. The merger happened before this sound change, but had it not, the negatives of the two verbs would have collided anyway.)

Auxiliary negative verbs

However, although these sentences are all proper and grammatically acceptable, in many cases a Poswa speaker will want to emphasize at the very beginning of the sentence that the verb is negative. After all, Poswa sentences often place the verb at the end of the sentence, and some sentences can be quite long. There are several auxiliary negative markers to choose from, and although they can be placed throughout a sentence or clause, they are generally placed at the beginning. The different auxiliaries have different shades of meaning:

Pubi pappopepebi.

No, I didn't bite you.

Pwupofi pappopepebi.

I didn't bite you yet. (So watch out.)

Pupebi pappopepebi.

I didn't bite you. (Someone else must've done it!)

Pupi pappopepebi.

I avoided biting you. (You don't look very tasty.)

Also, since they are grammatically considered intransitive verbs, the auxiliaries change to accomodate different person and tense markers. Essentially, they agree with the main verb in person and tense, but not always transitivity:

Pupi papapapopi pappopepebi.

I avoided biting my snake.

Pupel papapapo pappopepebel.

My snake avoided biting me.

Suppletive negative forms

Some verbs, however, do not take the infix -pep to become negative, but have instead suppletive forms which behave as independent verbs. This class includes all verbs that end in -o apart from the -o class's own irregulars, such as pappo above. Thus, using the verb popo "to speak, talk, converse", one can say

Poparabo.

I'm talking to you.

The change of -o- to -ar- here is regular, and one would expect it to change back to -o- again for the negative form. However, one cannot say

*Pubo popopepabo.

No, I'm not talking to you.

Because popo belongs to the class of verbs that have suppletive negative forms. Originally, a large percentage of Poswa verbs had suppletive negative forms, and they were easily remembered because there were not many irregular verbs to complicate the picture. However, as the number of irregulars grew, suppletives became less predictable, and they hung on only in certain commonly used verbs and in the regular -o conjugation class. Thus, instead, one hears sentences like

Pubo pofwabo.

No, I'm not talking to you.

Where the last consonant before the -o is replaced with a mutated form and the -o itself is replaced with labialization, thus placing the verb into the -y class. Largely, this irregularity remained in the language because it made the verbs it applied to two syllables shorter, and because all regular -o verbs otherwise conjugated the same way. The operation that produced this alternate negative verb stem did not shorten other classes of verbs as much, and in many cases the negative stem simply merged with the affirmative early on, thus forcing the Poswobs to adopt fronted auxiliaries and the infix -pep.

Other suppletive negatives

Most verbs with suppletive negative forms are in the -o class, as above. However, many commonly used verbs are not, and have retained suppletive negatives simply for ease of use. Often, these are found as complaints or as quick replies to polar questions, and are often used by themselves without the fronted auxiliaries common in longer sentences:

Šifo.

I don't know.

Žampfo.

I don't understand.

Utšwo.

I don't remember.

Wafebo.

I can't help.

Mipfo.

I can't see.

It is not improper to use the fronted auxiliaries here, although it is less common. Despite being suppletives, these verbs are still perceived by Poswa speakers as having an inherently negative meaning, and could be compared to English sentences such as "No, I missed it":

Pupebo wafebo.

I can't help. (Hopefully someone else can.)

Pep as a standalone verb

The infix -pep used above can still function as a standalone verb, and is considered to be part of the suppletive class because it is assigned to the verb bu "to do", but replaces the stem of that verb instead of attaching to it:

Pepebi!

I didn't do it!

A small number of Poswa verbs early on acquired -bu as a suffix (generally to repair a defective verb that had coalesced with a different verb or become highly irregular), and these verbs replace what is left of the -bu with -pep when they turn negative.

Other standalone negative verbs

Some of the other verbs up above can also be used in standalone form as an elliptical way to deny a previous thought or statement. They are always intransitive, regardless of the transitivity of the action being referenced. The most commonly used is

Pupi!

I didn't!

I didn't do it!

I didn't do anything!

And so on. This verb in other contexts has the specific meaning of deliberately avoiding something, but is used in a more neutral sense when it functions as a standalone verb because the verb

Pubi!

I didn't (do it)!

can also mean

I drew.

Despite the fact that this pubi is usually transitive, the confusion of meanings leads to speakers avoiding pubi in favor of pupi. The others behave essentially the same way:

Pwupofi!

I haven't done it yet!

Pupebi!

*I* didn't do it!

Infinitive

There is no true infinitive, but, in transitive verbs, what functions as one can be formed by changing "bo" to "va" in those forms that end in -bo. The passive form of this changes the va to la. This is called an impersonal verb rather than an infinitive.

Thus, for example, from the noun posapa "fire" comes the verb posafava "to burn (up)", and its passive form posafala. This is best understood as a verb that is inflected for voice and tense but not for person, so posafava really means "someone is burning something" and needs additional words in order to take on the functions of an infinitive. Note that this pattern exists only for transitive verbs. For intransitive verbs, the suffix -(b)a (originally a particle) is used. This suffix forms verbs that in English would often be adjectives. It is not etymologically related to the 3rd person intransitive present tense verb ending -ba, but has come to be treated as if it were the same ending, thus heightening the impression that most "adjectives" are merely intransitive verbs.

Serial person marking

Functions that in many languages are given to infinitives are done in Poswa and Pabappa by verbs inflected for person. This leads to internal rhymes, because all verbs, even irregular ones, reliably use the same vowels for the same person markings. Thus for example

Banambo¹ papibabo.²

I enjoy¹ spitting on you².

However, with passive verbs, an impersonal form is sometimes called for, to show that the action being described is not being performed by the speaker:

Tiša banambae papibala?

Do you enjoy being spit on?

has no person marking on its verb, and thus does not rhyme. It contrasts with

Tiša banambae papibažae?

Do you enjoy being spit on by me?

which has a 2nd person marker on the verb, and is passive, and thereby implies 1st person agent. This could be replaced with

Tiša banambae papibabo?

Do you enjoy me spitting on you?

which has an active verb and a 1st person marker, but the passive form is more common because Poswobs prefer to use the rhyming verbs to show agreement even though the agent of the first verb is the patient of the second.

Subject incorporation

Poswa verbs can incorporate indefinite subjects. For example, taempos means "children playing with each other". This is a compound of tae "children" + mušos "playing with each other". It is conjugated the same as any other verb, so the one-word sentence "Taempoša" means "Some children are playing with each other."

Toddlers on the treadmill

The incorporated subject is tae, which means "young children", but is not the most common word for children as it has been mostly replaced by pwopwa. Verbs with incorporated subjects often preserve fossilized meanings of nouns. For example, tae meant toddler originally, and is the same word as Khulls lē which generally refers to children who can walk ("toddle") but still need diapers (lé). As above, tae is rarely used as a subject in modern Poswa, but survives in various other uses, such as a child equivalent to the agent suffix -ta, which has come to be restricted to adults. For example, pwampta means a cashier or shopkeeper, but a pwamptae can mean a young child helping out in her mother's carpet store or a preschooler running a lemonade stand. Like many words, it can be used metaphorically, and has even come to be used for adults as a form of familiar address. Meanwhile, an old word for baby, bul, has moved up and pushed out tae in many of its original uses for children. For example, the commonest word for "to guess" is besse, originally meaning "baby's answer, baby's solution" because a baby can only guess at anything it wants to know. But it came to be seen as "child's answer" before its meaning became fixed. Then a word originally meaning fetus or embryo, bamba, came to be the commonest word for a human baby, and the new coinages pammo and wabvi took over for fetus.

Nevertheless, one would not simply say *Tae taempoša to indicate that a specific group of children are playing with each other. It would be grammatically correct, but tae is rarely used as a subject. Any word could do, but the most common word for children in modern Poswa is pwopwa, from a word originally meaning an apprentice. This word, like other words, is unmarked for number, but takes the plural suffixes -bum and -by to indicate that that being plural is significant to the meaning of the sentence. Thus, the sentence Pwopwabum taempoša has the same meaning as just Taempoša alone, but has a definite subject (i.e. "the children" rather than "some children") and is more emphatic. It could be used to mean "the children are playing with each other like children often do." (If the noun were singular, but the verb retained the -s ending, the meaning would be taken as "the child is playing with himself".)

The purpose of subject incorporation is to make new verbs that can be used with other subjects. While taempos does mean "children playing with each other", it can be used for adults in a metaphorical sense to indicate that they are behaving like children (in this case, it is nearly always a compliment, not an insult). These compound verbs are no different than simple noun+verb compounds except for the fact that sound changes which do not normally apply across word boundaries are allowed to take place, and some coinages which were made far back in history retain sound changes that have accumulated over time. This is why the part of the word that means "play with each other" is simply -mpos, which would not be pronouncible in isolation.

Incorporation of inanimate nouns

Pipsis is another subject-incorporating verb, but pipi "tree" is inanimate, so the meaning is passive with respect to the tree, and the sentence needs an animate subject to make sense. The word pipi for tree is rarely used in modern Poswa, as it is homophonous with several other words, but it still is used in the narrower sense of a fruit tree (a meaning shared with the longer pispum). Thus, although pipsis is widely understood, the first part of the compound is sometimes replaced with a different morpheme, resulting in words such as pispumpis, fampis, ipisis, povvasis, publofsis, pobbasis, popesis, and so on. Note that the verb for "sleep" is normally sys, but the sound-mutated version from pipsis has carried over to the other words and is effectively now a second verb for sleeping.

Passive animate incorporation

Purely from a syntactical perspective, sometimes even a noun that appears to be an incorporated subject can assume a passive role. For example, as above, tae "children" is animate, and functions as an agent in words such as taempos "children playing with each other" and talsafi "children counting on their hands", both of which can be used metaphorically or literally. However, the verb taeppa "to kidnap, abduct" also exists, and its structure is essentially the same as that of its English counterpart: tae "children" + -ppa "to abduct"; i.e. "kid" + "nab". Thus, despite the lack of an accusative marker on tae, the verb is readily understood to refer to a child victim and not a child perpetrator when used in everyday speech.

Nevertheless, when used with definite subjects, the subject of the sentence again takes on the active role. Thus

Pwopwabum raefobop taepfebel.

means

"The children kidnapped the toads."

rather than "The children were kidnapped by toads" or "the children made toads kidnap them" or some other such thing. Likewise the simpler sentence

Pwopwabum taepfel.

still means

"The children kidnapped [someone]."

rather than referring to the children themselves being kidnapped by an outsider. Further, the unlikely construction

Pwopwa laserbop taepfebel.

translates as

"The child kidnapped the enemy soldiers." (He was a pacifist who just wanted to protect his people.) indicating that the meaning of the verb holds regardless of how implausible its implication.

Incorporation of inalienable nouns

Body parts and other inalienable nouns can also be placed before a verb. In this case, they really are considered subjects, but only because they derive their animacy from an unspoken possessor. Often, especially with body parts, these words serve mostly as intensifiers, as the verb is generally already specific enough to get the meaning across clearly.

For example:

Pappapwebi.

means "I slapped you.", and

Peppapwapwebi.

means "I slapped you with (my) hand". The meaning is essentially the same in both words, but peppapwapwebi implies a more forceful slap. (The change of -pp- to -pw- is due to a sound rule.)

Forming questions

Yes-no questions

There is no "interrogative" mood for verbs in Poswa. In many contexts, a sentence can be made into a question simply by placing the verb into the subjunctive mood and leaving everything else, including the word order, intact. However, in most situations Poswobs will mark the sentence as a question in other ways, such as using question particles. Tus, placed at the beginning of a sentence, makes that sentence into a yes-no question. At the end of a sentence, the particle pa, which means "or" in certain contexts, can also be used. This is generally "spaced" away from the preceding sentence by a pause intended to draw the listener's attetnion, even when the context is already clear. Double-marking a sentence by beginning with tus and ending with pa while also placing the verb into the subjunctive mood is optional but not frowned upon.

Thus:

Wivafta¹ pešfop² posapebel.³

The teacher¹ burned³ the book.²

contrasts with sentences such as

Tus wivafta pešfop posapebep, pa?

Did the teacher burn the book, or ...?

Non-accusative verbs

All verbs in Poswa have an unspoken and unwritten prefix showing which case the object of the verb is placed into. Most verbs govern the accusative case, and the prefix that shows this is wi. This is considered part of the verb, but is never pronounced or written down even in a dictionary. It is considered a separate word. Thus, for example, the verb for "to promise" in Poswa is technically wi pambap, but even in a dictionary, one will only find an entry for pambap.

Verbs that govern cases other than the accusative have different prefixes. These are still normally unspoken and unwritten, but will appear in a dictionary in order to remind the student of the proper use of the verb in question.

Locative verbs

For example, the verb for "to become" is dži tiša. It is both a highly irregular verb and one that places its object into the locative case rather than the accusative. The verb behaves mostly as if its stem were a hyper-regular p-. Thus one can say

Pobbam pebel.

He became an oak tree.

(The tiša stem contracts to simply p- because of sound rules that are triggered in constructions such as this where two words are spelled separately but treated as a prosodic unit.) Because of the potential for confusion, this verb is usually used directly after its object; that is, the word order is not flexible the way it is for most accusative verbs. Thus, for example, one would not normally say

*Pobbam pwuwumbam pebel.

He became an oak tree in the forest.

Because the speaker would likely initially hear the sentence as if pwuwumbam "in the forest" were the object of the verb, and thus imagine a man becoming a forest while trapped inside an oak tree.

Interjections

Interjections can be considered to be either a subset of the nouns or a subset of the verbs. However, going far enough back in the history of the language, the "verb" analysis is shown to be the only correct one, as the nouns that resemble interjections were themselves originally verbs.

Saying yes and no

Yes

The word for "yes" in Poswa is a verb derived from an obsolete stem meaning "correct, right". Thus Poswobs saying

Ipae!

Yes!

Are really saying "You're right!" And therefore, the verb can be conjugated like any other verb, producing

Ipo!

Yes! (I'm right!)

Ipa!

Yes! (They're right!)

Wivafta ipa!

Yes! The teacher is right!

And so on. As vowel-initial words are rare in Poswa, the verb has had an alternate stem without the initial i- for thousands of years, but this is generally only used when the entire verb is repeated twice, producing

Paepae!

Yes yes!

Though even this is rare outside of the 2nd person form, since both popo and papa have other established meanings.

No

Saying "no" is a bit more complicated. The simplest and most straightforward way to contradict someone else is to use pupa, the verb for "to avoid", which early on acquired a secondary sense of "to be wrong" in some contexts. (It originally had the narrow meaning of "to look away; to shut the eyes; to avoid looking at something" and thus to be wrong was seen as similar to being afraid to look at the truth in front of one's eyes.)

Second person usage

Generally, this verb is encountered in the second person, as a sentence by itself. (This is why the two meanings of the verb are not often mistaken for each other.) It is hyper-regular, so the -p- does not change to -f- as one might expect. Thus one will often hear:

Pupae!

No! (You're wrong!)

First person usage

However, pupa is as much a verb as any other, and therefore can take any person or tense marker. In the first person, it can be used to indicate mistakes:

Pupo! Pwosebi wave pappamemiop!

Whoops! I gave you a placebo!

In the third person, it can still correspond to English "no", but generally implies a meaning such as "he's wrong":

Pupa! Pupi pafiopi pimbolebi!

He's wrong! I didn't steal the banana!

Expressing emotions

Nevertheless, interjections have carved out a niche for themselves in Poswa, and the speakers do not often think about what grammatical part of speech they should be grouped with. Poswa's interjections are often seen as childish and rude by surrounding cultures, as the Poswobs have a tradition for verbal bluntness that is rare even among their close relatives.

Many interjections are used to express pain and unpleasant emotions. For example, a Poswob speaker who was too slow at getting through a revolving door might say Pup!, which is the accusative case of an obsolete word for hand. Thus, it can be analyzed as roughly equivalent to the English "Ouch! My hand (got hurt)!" even though the word for hand from which pup is derived is no longer in use in modern Poswa.

Many of the interjections are one syllable long, but some have two or three syllables. Poswob children learn early to say

Bevo!

I have to go to the bathroom!

This is historically descended from a longer verb that got worn down over several thousand years of sound changes. It is cognate to the modern words bwem "bathroom" and vub "to spray".

Interjections and incomplete sentences

In Poswa, many sentences that might seem incomplete are actually grammatically correct. For example, in English one might say "Of course!" and be told that it's merely a sentence fragment rather than a sentence. But in Poswa it is difficult to think of a sentence that is ungrammatical, since both verbs and nouns can stand alone. However, only a verb can stand alone without an implied dependence on another sentence. Thus interjections like

Nubampoža!

Of course!

are grouped with verbs rather than nouns.

Conjugation tables

-a

The verb luba "to change color, repaint" is used here as an example of an -a verb.

luba		Past	Present	Imperative
Intransitive	1st person	lubi	lubo	lubub
	2nd person	lube	lubae	lubi
	3rd person	lubel	luba	lubob
Transitive	1st person	lubebi	lubabo	lubbub
	2nd person	lubebe	lubabae	lubbi
	3rd person	lubebel	lubaba	lubbob

Thus one can say

Blebblobopi lippipa lubebi.

I painted the wall green.

But

Lusafampi lubi žužum.

I turned pink from embarrassment.

After discovering you've painted over the windows as well.

Consonant mutation

The -a- conjugation class undergoes consonant mutation for the consonant before the final vowel. The verb above had a -b- before the final vowel, and the mutated form of -b- is still -b-, thus masking the effect. Thus, when a verb whose stem ends in -ba preceded by a vowel or an -m-, the verb will behave as if the -ba were not there at all. This has led to collisions among previously distinct verbs, generally causing one of them to disappear from the language. Occasionally, though, the "losing" verb grabs onto the surviving one as a little-used alternate meaning, often with metaphorical usage.

For example, the verb biba "to lick" merged with the verb bi "to kill"; bibabo could have meant either "I'm licking you" or "I'm killing you". The meaning "lick" won out, but acquired just a bit of the flavor of the other verb, in that it can be used in a sense rather like "to lick away".

/b/ is not the only consonant that is its own mutation; for all verbs whose stems end in one of these consonants plus an -a, the consonant will remain the same in all verbal conjugations and the -a will drop out. However, only -b- has the additional property of appearing after verbs whose stems end in a vowel or -m, and therefore only the final syllable -ba behaves entirely as if it were not there.

For consonants that do mutate, the following tables of mutating conjugations are followed.

-pa

-p-

Below is the conjugation for pialipa "to cartwheel, roll around on one's hands and feet":

pialipa		Past	Present	Imperative
Intransitive	1st person	pialifi	pialifo	pialifub
	2nd person	pialife	pialifae	pialifi
	3rd person	pialifel	pialifa	pialifob
Transitive	1st person	pialifebi	pialifabo	pialifpub
	2nd person	pialifebe	pialifabae	pialifpi
	3rd person	pialifebel	pialifaba	pialifpob

Note the change of the expected -b- to -p- in the transitive imperative.

This verb is often used transitively in a metaphorical sense, so one can say

Pobbliop,₁ pialifebi.₂

Sorry,₁ I bumped into you.₂

With the implication of "Sorry, i just disrupted your plans or messed up something you built."

-ma

-m-

Below is the conjugation for brama "to bite (off), as with a beak; to cut with a uniformly sharp instrument":

brama		Past	Present	Imperative
Intransitive	1st person	bravi	bravo	bravub
	2nd person	brave	bravae	bravi
	3rd person	bravel	brava	bravob
Transitive	1st person	bravebi	bravabo	bravbub
	2nd person	bravebe	bravabae	bravbi
	3rd person	bravebel	bravaba	bravbob

Thus one can say

Bravbi!

Bite me!

Twup!₁ Loppasufo₂ bravaba;₃ sas₄ pop₅ pubbvub₆ pelpies?₇

Ouch!₁ My pet falcon₂ is biting me,₃ can₄ we₅ talk₆ later?₇

Bovepiopi₁ bulžirebi,₂ wa₃ po₄ bravebi.₅

I grabbed₂ my teething ring,₁ and₃ bit it₅ hard.₄

The similarity between a baby's mouth and a bird's is that neither of them have (many) teeth, and therefore they both bite with a smooth flat surface rather than a many-pointed one. Other verbs are used for biting animals that have teeth. It can also be used for inanimate objects:

Leppiapiub,₁ rulpos₂ lompapi₃ bravebi.₄

With my scissors,₁ I cut off₄ the corner₃ of the napkin.₂

Intransitive	1st person	wupwawie	wupwawio	wupwawiub
	2nd person	wupwawie	wupwawiae	wupwawie
	3rd person	wupwawiel	wupwawia	wupwawiob
Transitive	1st person	wupwawiebi	wupwawiabo	wupwawiabub
	2nd person	wupwawiebe	wupwawiabae	wupwawiabi
	3rd person	wupwawiebel	wupwawiaba	wupwawiabob

Pwopwabum, pwawam raffep blabem wupwawiabi.

Children, please write your names on your papers.

Note that the 1st and 2nd person intransitive past forms are the same because Poswa does not allow two identical vowels to appear next to each other, and therefore changes the otherwise expected -ii into -ie.

Non-mutating consonants

For non-mutating consonants followed by -a, the verb conjugation works like that of -ba. Below is the conjugation of puffa "to rely on":

	Agent	Patient	Past	Present	Imperative
Intransitive	1st person	—	puffi	puffo	puffub
	2nd person	—	puffe	puffae	puffi
	3rd person	—	puffel	puffa	puffob
Transitive	1st person	2nd person	puffebi	puffaba	puffypub
		3rd person
	2nd person	1st person	puffebe	puffabae	puffypi
		3rd person
	3rd person	1st person	puffebel	puffaba	puffypob
		2nd person

-e/-i

As Poswa inherited the "a e i o u" vowel order from Pabappa, and places its vowels before its consonants, the second conjugation is the one representing verb stems ending in -e or -i. The verb wape "to help, provide for" is used here as an example of an -e verb. The endings would be the same if the verb ended in -i instead. Unlike the -a conjugation, the -e/-i conjugation always adds a syllable to the intransitive form and two syllables to the transitive form. This is because the final vowel of the verb stem does not collapse the way it does in the -a words. This, in turn, is due to analogy with a small number of verbs that had previously ended in a consonant but lost that consonant.

wape		Past	Present	Imperative
Intransitive	1st person	wapebi	wapebo	wapebub
	2nd person	wapebe	wapebae	wapebi
	3rd person	wapebel	wapeba	wapebob
Transitive	1st person	wapebebi	wapebabo	wapebbub
	2nd person	wapebebe	wapebabae	wapebbi
	3rd person	wapebebel	wapebaba	wapebbob

Pimpubbum mapobiep wapebaba faspavas.

The boys are helping the girls with their chores.

Past tense intransitive verbs whose stems end in -e often resemble transitive verbs whose stems end in -a or a consonant, since -e- is the vowel that marks the past tense. For example, the sentence

Pavebi.

can mean either

I tied you (up).

In which case it is a derivative of the verb pama "to tie, make a knot", or

I used crutches.

In which case it is a derivative of the word pave "crutch". This rarely causes confusion for Poswa speakers because few sentences use verbs in which it is ambiguous whether that verb is transitive or intransitive, even when (as in the example above) the object of a transitive verb is omitted. Moreover, these coalescences can only happen with intransitive -e verbs that have one of the consonants that mutates to itself before the -e.

-o/-u/-y

A more complicated setup is the third conjugation, that which reflects words ending in the rounded vowels /o/, /u/, and /y/ (a rounded schwa-like sound).

The verb subu "to conquer, take over" is used here as an example of an -u verb. The endings would be the same if the verb ended in -o or -y instead, but note that most verb stems ending in -o do not belong to this conjugation.

subu		Past	Present	Imperative
Intransitive	1st person	subwi	subwo	subwub
	2nd person	subwe	subwae	subwi
	3rd person	subwel	subwa	subwob
Transitive	1st person	subwebi	subwabo	subwubub
	2nd person	subwebe	subwabae	subwubi
	3rd person	subwebel	subwaba	subwubob

The first person imperative is used in the sense of "let me X!", so the one-word sentence Subwubub! would mean "Let me take you over!" (If no object is given, it is understood to be a 2nd person object.) Whereas the third person imperative is also used with a similar sense: Pupipup subwubob! translates as "Let him take over the world!"

Most verbs in this conjugation class end in -u or -y. One of the few that ends in -o is pappo "to bite".

-p

The first consonant-stem conjugation is the -p conjugation, because /p/ is the first consonant in the Poswa alphabet. Since all reflexive verbs end in /p/, this conjugation is more common than the other consonant conujgations. However, many verb stems that end in /p/ are normal verbs, not reflexives. The verb blop "to see, focus" is used below as an example of a non-reflexive /p/ verb. Note that, unlike the vowel conjugations above, the transitive form is not merely derived by inserting the infix "-ab-" into the intransitive form.

blop		Past	Present	Imperative
Intransitive	1st person	blofi	blofo	blofub
	2nd person	blofe	blofae	blofi
	3rd person	blofel	blofa	blofob
Transitive	1st person	blopebi	blopabo	bloppub
	2nd person	blopebe	blopabae	bloppi
	3rd person	blopebel	blopaba	bloppob

Thus one can say

Muššiepi bi bloppi!

Look at that horse!

-m

The -m conjugation is very simple. It does not matter what the vowel preceding the final -m is, because there are neither vowel changes nor consonant changes in the stem.

The verb pessam "to cuddle, hug, squeeze someone" is used here as an example of an -m verb.

pessam		Past	Present	Imperative
Intransitive	1st person	pessambi	pessambo	pessambub
	2nd person	pessambe	pessambae	pessambi
	3rd person	pessambel	pessamba	pessambob
Transitive	1st person	pessambebi	pessambabo	pessambybub
	2nd person	pessambebe	pessambabae	pessambybi
	3rd person	pessambebel	pessambaba	pessambybob

Thus, all -m verbs conjugate the same way that they would if they instead ended in -mba. Indeed, another verb for hugging is mamba, and it conjugates the same as it would if it were mam. Thus one can say:

Pessambabo! Mambabo!

I'm cuddling you! I'm hugging you!

-s

The -s conjugation has a few slipups. The verb pipsis "to sleep in a tree, camp out" is used here as an example of an -s verb.

pipsis		Past	Present	Imperative
Intransitive	1st person	pipsiši	pipsišo	pipsišub
	2nd person	pipsiše	pipsišae	pipsiši
	3rd person	pipsišel	pipsiša	pipsišob
Transitive	1st person	pipsisebi	pipsisabo	pipsispub
	2nd person	pipsisebe	pipsisabae	pipsispi
	3rd person	pipsisebel	pipsisaba	pipsispob

Note that the transitive sense of verbs like pipsis is not "to sleep in a tree" (with the tree as the object of the verb) but "to sleep (someone) in a tree; to put someone to sleep in a tree" and thus one would not normally find a word for tree in the accusative in this sentence. If the tree is mentioned, it would be in the locative case. Thus, with both pronouns understood, Pipsispi fadžam can mean "I put you to sleep in a palm tree". (It can also mean "(You) put me to sleep in a palm tree!" (imperative), but this would be distinguished by tone of voice and context.

Some verbs ending in -s have a reflexive meaning, even though the reflexive ending in Poswa is -p. This refers to an old sense related to the genitive, in which verbs for things like "to comb one's hair" (pampapes) were used with the genitive instead of the accusative. These verbs are generally used only intransitively, because the transitive meaning of, for example, pampapes is not "to comb someone else's hair" but "to make someone comb their hair".

Distance verbs

/-s/ can also indicate "distance verbs". e.g. tura = "bomb"; turas = "there are bombs here". wap = "to be happy"; wakas = "for you to be happy". Hence Wakašo "I make you happy" etc

-l

Most verb stems that end in -l belong to the -el or -ul subcategories. Less common are -il and -ol; there are a few verbs whose stems end in -yl which behave the same as the -ol verbs. No verb stems end in -al; roots Romanized with a final -al actually end in a phonemic /alʷ/.

-el

The verb pelpel "to pounce" is used here as an example of an -l verb.

pelpel		Past	Present	Imperative
Intransitive	1st person	pelpeži	pelpežo	pelpežub
	2nd person	pelpeže	pelpežae	pelpeži
	3rd person	pelpežel	pelpeža	pelpežob
Transitive	1st person	pelpelebi	pelpelabo	pelpelbub
	2nd person	pelpelebe	pelpelabae	pelpelbi
	3rd person	pelpelebel	pelpelaba	pelpelbob

Thus one can say:

Sanža puvlwap pelpelebel.

The boy pounced on the cougar.

-o

The -o conjugation is considered a consonantal one, because it reflects a lost final /r/ that changed to /b/ in some words but coalesced with the preceding vowel in others. This is why most verb stems with final -o are not in the -o/-u/-y conjugation above, but rather in this one. This conjugation can be called B5 because it is traditionally the fifth of the consonantal conjugation classes. The verb poto "to chase down, run and catch, as in war" is used here as an example of an -o verb.

poto		Past	Present	Imperative
Intransitive	1st person	potabi	potabo	potabub
	2nd person	potabe	potabae	potabi
	3rd person	potabel	potaba	potabob
Transitive	1st person	potarebi	potarabo	potarybub
	2nd person	potarebe	potarabae	potarybi
	3rd person	potarebel	potaraba	potarybob

Potarabo saffapop.

I'm catching butterflies.

-ob

A subtype of the B5 conjugation exists for verbs whose stems end in -ob or -u and historically ended in an -r. Below is the conjugation of the verb povbob "to become pregnant":

povbob		Past	Present	Imperative
Intransitive	1st person	povbwi	povbwo	povbwub
	2nd person	povbwe	povbwae	povbwi
	3rd person	povbwel	povbwa	povbwob
Transitive	1st person	povbwebi	povbwabo	povbwubub
	2nd person	povbwebe	povbwabae	povbwubi
	3rd person	povbwebel	povbwaba	povbwubob

The implied object of this verb is not the child being conceived but the father of the child. Thus

Povbwebi blebbelmeptap.

means "I got pregnant through the bricklayer", not "I got pregnant with the bricklayer".

This is essentially identical to the -u conjugation above, despite arising from a stem-final consonant rather than a stem-final vowel.

-ub

A subtype of the B5 conjugation exists for verbs whose stems end in -ub or -u and historically ended in an -r. Below is the conjugation of the verb bivub "to advise, sponsor":

bivub		Past	Present	Imperative
Intransitive	1st person	bivibi	bivibo	bivibub
	2nd person	bivibe	bivibae	bivibi
	3rd person	bivibel	biviba	bivibob
Transitive	1st person	bivirebi	bivirabo	bivirybub
	2nd person	bivirebe	bivirabae	bivirybi
	3rd person	bivirebel	biviraba	bivirybob

Note that the final vowel in the stem changes to i even though the bare form of the word has an u. Neither vowel is the original; the original vowel in most words in this class was y, which changed to u in most closed syllables and i in most open ones.

Hyper-regular verbs

Most Poswa verbs that end in -a or a consonant involve some form of consonant mutation. However, in a few verbs, the mutated consonant has merged with the original consonant due to succeeding sound changes. Thus, the verb can be said to be hyper-regular since it avoids even the normal changes that other Poswa verbs undergo. Most of these verbs end in -ba, since the mutated form of b is simply b. However, since this pattern is regular and entirely exceptionless (that is, there are no verbs ending in -ba that mutate it to something else), these -ba verbs are not considered to be hyper-regular. The same analysis applies to verbs whose stems end in -a preceded by one of the consonants f v š ž tš dž, as these consonants are the same as their respective mutated forms. Thus, all verbs ending in any of -ba -fa -va -ša -ža -tša -dža will not mutate during their conjugations.

However, some non-mutating verbs end in -pa or in a sequence that becomes -pa after mutation. Since the normal behavior for -pa is to change to -f-, these verbs are singled out as hyper-regular verbs. Below is the conjugation of pypumpa "to pull":

pypumpa

The verb pypumpa "to pull" is a hyper-regular verb:

	Agent	Patient	Past	Present	Imperative
Intransitive	1st person	—	pypumpi	pypumpo	pypumpub
	2nd person	—	pypumpe	pypumpae	pypumpi
	3rd person	—	pypumpel	pypumpa	pypumpob
Transitive	1st person	2nd person	pypumpebi	pypumpabo	pypumpybub
		3rd person
	2nd person	1st person	pypumpebe	pypumpabae	pypumpybi
		3rd person
	3rd person	1st person	pypumpebel	pypumpaba	pypumpybob
		2nd person

Thus one can say:

Pimpup puvapwop wubbuwavbem pypumpebel.

The boy pulled on the door of the jail.

Pypumpa belongs to a small class of verbs where the mutated form of the consonant is the same as the original. In an older stage of the language, the word was pypumpsa. The mutated form of this verb was pypumpša, but a sound change of -mp[flrsšt]- > -mp- merged the two. This particular sound change only triggered when an -m- was present before the -p-.

Irregular verbs

Poswa has many irregular verbs, although many of these can be treated as regular if the speaker imagines an "oblique" stem that replaces the nominal stem from which the verb was originally derived. These oblique stems often end in consonants or clusters which are not permitted at the end of Poswa words and therefore are not usually thought of as independent words.

Examples of irregular verbs

See Poswa irregular verbs for a partial listing.

mi

The verb mi "to see" is an irregular verb with a stem change to the oblique variant v-:

	2nd person	ve	vae	vi
	3rd person	vel	va	vob
