Tsakxa verbs

Verbs in Tsakxa are comparatively heavily inflected, conjugating by aspect, mood and voice. There are two classes of verbs, the monopartite verbs (which have a single stem and are conjugated regularly) and the bipartite verbs (which have a bipartite stem and whose conjugation is far more complex and irregular).

Commonalities

Polarity

Negativity is marked with the particle pa, which is placed in a variety of places depending on emphasis and personal taste. Reduplication to apa creates an emphatic 'no' or 'never':

Wen-ø wes-enxa-ø apa su - I never eat meat (meat-TOPIC eat-IMPERF-INDIC never 1ps)

An emphatic declarative is also possible with the particle ʔu which works in much the same way as pa:

Wen-ø wes-enxa-ø ʔu su - I always eat meat (meat-TOPIC eat-IMPERF-INDIC DECL.EMPH 1ps)

Voice

In finite forms, the passive voice is marked with the particle, or prefix, se. This precedes the verb:

Wen-ø se wes-enxa-ø - as for meat, it's always being eaten

The passive voice is always used when the topic is the patient of the verb. It has been argued that the voice is more an agreement clitic than an actual voice marker.

Monopartite verbs

Monopartite verbs are by far the more common type of verb in Tsakxa. They have a single stem, as implied by the name, and take only suffixes for inflection, other than the evidentiality prefix.

Evidentiality

All verbs carry inflection for evidentiality. There are three degrees of evidentiality:

Certainty (marked by the prefix ø-), used when the speaker observed the act in question or is certain that it occurred:

Sesu-ø uʔ-a ø-ta-ngxu su - your sister saw you (sister-TOPIC 2ps-DAT PASSIVE CERT-see-PERF 2ps)

In future contexts use of the null prefix is emphatic:

Nenqa-ø patangqa se ø-ta-ngxu - I WILL see Nenqa tomorrow (nenqa-TOPIC tomorrow PASSIVE CERT-see-PERF)

Uncertainty, marked by the prefix anu-, is used for reported speech and events that may have happened:

Nenqa-ø uʔ se anu-ta-ngxu - you saw Nenqa (didn't you?)

There is a strong overlap with the dubitative here - original analyses treated this as a circumfix with the dubitative suffix but there are instances of one occurring without the other. The dubitative implies something slightly different from the anu- prefix - anu- simply confirms that the speaker was not present at the event and cannot vouch completely for what happened. The dubitative gives a degree of actual distancing from the event:

Nenqa-ø aʔ se anu-ta-ngxu - I believe that he saw Nenqa (but I wasn't actually present at the time)

Nenqa-ø uʔ se anu-ta-ngxu-l - He says/people say that he saw Nenqa (but I don't know whether to believe it)

The final evidentiality prefix denotes hypotheticality, marked with atu. This states that the event never in fact happened:

Nenqa-ø uʔ se atu-ta-ngxu - you would've seen Nenqa/say you'd seen Nenqa

Aspect

All verbs carry inflection for aspect (perfective or imperfective). In monopartite verbs, this is accomplished by the addition of a suffix.

Perfective aspect

The Perfective aspect implies a single action, complete and independent of any other action and is formed by (e)ngxu (the /e/ assimilates to a preceding vowel and causes lenition of /t/ to /s/ and /p/ to /f/ in preceding consonants). For example:

Sesu-sa se ø-ta-ngxu - I saw/see my sister at one point (sister.TOPIC-PERSONAL PASSIVE CERT-see-PERF)

The perfective does not imply any kind of past tense, and can be used in the future for any distinct single action:

Sesu-sa patangqa se ta-ngxu - I will see my sister tomorrow (sister.TOPIC-PERSONAL tomorrow PASSIVE see-PERF)

Imperfective aspect

The Imperfective aspect implies continuous or repeated action. It is formed with (e)nxa:

Sesu-sa se ta-nxa - I'm currently seeing my sister/I see my sister frequently (sister.TOPIC-PERSONAL PASSIVE see-IMPERF)

Sesu-sa se ta-nxa pangxu - I used to see my sister/I was seeing my sister last year (sister.TOPIC-PERSONAL PASSIVE see-IMPERF last.year)

Mood

All verbs also carry inflection for mood. There are four moods distinguished in Tsakxa:

Indicative

The Indicative mood describes actions that definitely have happened, will happen or are happening within the speaker's knowledge. It is marked by a null morpheme (shown here with -ø but not marked in the actual written language).

Kangqa se ta-ngxu - I saw the beast

It is also used for imperatives in almost all verbs:

Baʃung-ø se ugqe-kxa sut-ngxu-ø! - Read the book! (book-TOPIC 2ps-ERG read-PERF-INDIC)

Some verbs, however, have their own distinct imperative root:

Baʃung-ø se ugqe-kxa sang-ngxu-ø! - Look at the book! (book-TOPIC 2ps-ERG see-PERF-INDIC)

Subjunctive

The Subjunctive or Modal mood describes actions that may or may not have happened and that the speaker feels strongly about. It is marked by a suffixed -s:

Aʔ-ø, utxu-nxa-s - I hope he's dying somewhere (3ps-TOPIC die-IMPERF-SUBJ)

It is also used for 'if I were' sentences:

Su-ø, piʃ-enxa-s - if I were a rich man (1ps-TOPIC rich-IMPERF-SUBJ)

Dubitative

The Dubitative mood describes actions devoid of emotional content that the speaker wishes to distance themselves from - primarily reported speech. It is formed with the suffix -l:

Aʔ-ø, se utxu-nxa-l aʔ-m tik-enxa-ø - 'he says that he's dying' (3ps-TOPIC die-IMPERF-DUB 3ps-TOP say-PERF-INDIC)

Interrogative

The Interrogative is used to ask questions. It is formed with the suffix -f:

Uʔ-ø wes-enxa-f? - Will you be eating? (2ps-TOPIC eat-IMPERF-INTER)
