Proto-Imperial

Phonemes

Consonants

The consonant system of Proto-Imperial is characterized by a large amount of plosives and affricates (here called stops), with 4 different manners of articulation: lenis, fortis, glottalized and prenasalized at 5 different points of articulation, as well as the glottal stop. On the other hand there are few fricatives, and no phonemic nasals.

Fricative				s		ɕ			h
Approximant					l	(j)	(w)

The central approximants /w/ and /j/ can be treated as consonantal allophones of /u/ and /i/ respectively.

Vowels

Proto-Imperial has three contrastive vowel qualities /i, u, a/ at two different vowel heights (high, low). There are also two contrastive vowel lengths and a contrast in nasalization. There are also 4 diphthongs. This results in 16 phonemic vowels, shown below.

Oral, Long

	Front	Back
High	iː	uː
Low	aː

Oral, Short

	Front	Back
High	i	u
Low	a

Nasal, Long

	Front	Back
High	ĩː	ũː
Low	ãː

Nasal, Short

	Front	Back
High	ĩ	ũ
Low	ã

There are also 2 oral and 2 nasal diphthongs:

Closing to ɪ	aɪ	ãɪ
Closing to ʊ	aʊ	ãʊ

Syllable structure and constraints

The syllable structure is C(G)V(X), where

C is any (phonemic) consonant (i.e. no central approximant)

G is one of the two central consonants, [j] or [w]

V is any vowel or diphthong

X is one of the two glottal consonants, /ʔ/ or /h/

The central approximants cannot occur before the vowel of which they are allophones. In other words [w] does never occur before /u(ː)/ and [j] does never occur before /i(ː)/. The palatal approximant [j] does not occur after sibilants or affricates. It also doesn't seem to occur after uvular consonants. The labio-velar approximant [w] does not occur after the lateral affricates.

Stress

Word-stress in PI were not phonemical. The nature of the stress are unknown, but it is likely that it was some kind of pitch-accent. Even if the exact nature of the stress is unkown, we know which syllable was stressed.

The last checked syllable in the word, except for the very last syllable received primary stress. If no syllables in a word were checked, the first syllable of the word was stressed. Every other syllable, counting back and forward from the primary stressed syllable received secondary stress, last syllable of the word excluded. Note however that most words were 2 or 3 syllables long, and only received primary stress.

Morphology in PI were procliticizing, where the morphological containt were included in proclitics before the root words. These clitics were always unstressed.

Realizations and allophony

The realization and allophony of Proto-Imperial (PI) is based on the reflexes of the daughter language(s). Quite possibly many of these allophonies reflects the pronunciation of a rather late stage of PI:s history.

Consonants

The realizations of the consonants were depending on their location inside the word. In PI one differs between two locations, initial and medial. Initial position is initially in the word, or after a checked syllable (i.e. a syllable that ends with /ʔ/ or /h/) while medial position is after a non-checked syllable.

Stops

Lenis stops were pronounced voiceless in initial position, and voiced in medial position. They were voiced as such:

Lenis stops

Unvoiced	Voiced
p	b
t	d
k	g
q	ɢ
ʦ	ʣ
ʨ	ʥ
tɬ	dɮ

The affricates could further deaffricate to voiced fricatives in some dialects.

Checked syllables ending in /h/ + lenis stop was pronounced as a preaspirated stop.

Fortis stops were always voiceless. They were pronounced aspirated in initial position, and geminated and preaspirated in medial position. The difference between non-checked syllable + fortis stop and h-checked syllable + lenis stop is thus one of consonant length.

Glottalized stops were ejectives, except for the labial plosive, which was an implosive. Certain dialect also pronounced the alveolar plosive as an implosive rather than an ejective. There seems to have been no difference in pronunciation between initial and medial position for the glottalized plosives/affricates.

The pronunciation of prenasalized stops depended on the location but also on the quality of the following vowel. All prenasalized stops except the lateral affricate were pronounced nasal before a nasal vowel. They nasalize as such:

Nasal realization of prenasalized stops

Prenasalized	Nasal
mb	m
nd	n
ŋg	ŋ
ɴɢ	ŋ
nʣ	n
ɲʥ	ɲ

The ”nasals” were pronounced the same in initial and medial position. Notice the partial merger between /nd/ and {IPA|nʣ}}/ (to [n]) as well as between /ŋg/ and /ɴɢ/ (to [ŋ].

Before oral vowels and in initial position they were pronounced without the prenasalization, i.e. as voiced stops:

Voiced realization of prenasalized stops

Prenasalized	Voiced
mb	b
nd	d
ŋg	g
ɴɢ	ɢ
nʣ	ʣ
ɲʥ	ʥ
ndɮ	dɮ

Resulting affricates were never deaffricated.

In medial position before oral vowels they were pronounced as true prenasalized stops, but the same dialects that deaffricate medial lenis affricates also deaffricate medial prenasalized affricates, so that they become prenasalized fricatives: [nz], [ɲʑ] and [nɮ],[nl] or [lː]

Also note that several dialects failed to deaffricate the lateral prenasalized affricate in medial position, even if they deaffricate other affricates.

Other consonants

Other consonant show less allophony, but [h] was usually pronounced voiced [ɦ] when in coda and before voiced consonants (i.e. /ɓ/ prenasalized stops and /l/).

Vowels

Vowel realizations depended on the phonation type and/or the surroundings.

Nasal vowels were centralized, and vowels next to an uvular (phone) was lowered/backed.

Non-nasal non-backed /a(ː)/ was realized as [æ(ː)].

Realizations of vowels

Phoneme	Normal	Nasal	Backed/lowered	Nasal + Backed/lowered
a(ː)	æ(ː)	ɐ̃(ː)	ɑ(ː)	ɑ~(ː)
i(ː)	i(ː)	ɪ~(ː)	e(ː)	ɛ~(ː)
u(ː)	u(ː)	ʊ~(ː)	o(ː)	ɔ~(ː)

Vowels in syllables that are closed with [ʔ] were possibly pronounced with a glottalized vowel (i.e. creaky voice), at least in some dialects. The glottal stop could not be geminated, so when a ʔ-checked syllable were followed by an initial [ʔ] the coda disappeared, but the creaky voice of the preceding vowel probably remained, once again depending on dialect.

Romanization

The romanization scheme I've chosen for PI is neither phonemical nor phonetical, but rather a practical orthography.

Consonants

			Bilabial	Alveolar			Alveolo- palatal	Velar	Uvular	Glottal

Initial prenasalized consonant graphemes are used when the phoneme is in initial position and the following vowel is oral. Medial prenasalized consonant graphemes are used when the phoneme is in medial position and the following vowel is oral. Nasal prenasalized consonant graphemes are used when the following vowel is nasal.

Vowels

Short oral	Long oral	Short nasal	Long nasal
a	aa	ą/a	ąą/aa
i	ii	į/i	įį/ii
u	uu	ų/u	ųų/uu

	Oral diphthongl	Nasal diphthong
to ɪ	ay	ąy/ay
to ʊ	aw	ąw/aw

Nasal vowels are written as oral vowels after a nasal consonant, e.g. <ma> /mbã/ [mɐ̃]

Glottal stop

The glottal stop is unmarked:

1. Word initially, <aba> /ʔapa/ [ˈʔæbæ]
2. Between dissimilar vowels, <gai> /kaʔi/ [ˈkæʔi]
3. In coda, before an initial prenasalized non-nasal stop, <gazzi> /kaʔnʣi/ [ˈkæʔʣi]
