We'll start with the phonology, which many of you will have some idea of but here's a recap.
/p t t͡ʂ c ʔ/ <p t tr ty ‘>
/s x xʷ/ <s x xw>
/m n ɲ ŋ ŋʷ/ <m n ny ŋ ŋw>
/w ɾ j/ <w r y>
/i ə u/ <i u>
/ɛ ɑ/ <e ə a>
There are distributional restrictions on /ə/. Before a palatal consonant /c ɲ j/ is merges with /i/, while it merges with /u/ before labiovelars /xʷ ŋʷ w/. Additionally schwas assimilate to the quality of a following vowel after a glottal stop.
Syllable structure is CV(C), where coda consonants are restricted to /ʔ x n/. However there are multiple phonetic realisations for the fricative and nasal. /x/ is fronted to a coronal fricative /s~sʲ~ʂ/ <s> before coronal /t t͡ʂ c s n ɲ j/, with /j/ being deleted after this /s/, and /n/ assimilates to the place of articulation of a following consonant - this is written as <m> before labial /p m/ and <ŋ> before /ŋ w/, while the cluster /nx/ is simplified to /ŋ/. Additionally /ʔ/ is dispreferred immediately following another consonant - this crops up in both the abstract prefix ‘- and general nominaliser suffix -‘ə appear after a consonant, where metathesis happens, in the former case universally, the latter only with -t (min-‘uxra > mi‘nuxra "our fire", witə w-əmitrat-‘ə > witə wəmitra‘tə "a local person").
Stress is basically word-initial. Some speakers show shift to the post-initial in cases when the initial has a schwa and the post-initial a non-schwa vowel, but this isn't universal.
A final note is that one or two morphological operations which result in palatalisation of consonants.
Code: Select all
p, t > ty
x > s
m, n, ŋ > ny
ŋ > ns
xw > xuy
ŋw > ŋuy
‘ > ‘y
r > ay
tr > tyər
w > uy
ty, s, y show no change
As a result of the /r w/ sound changes some vowel contractions occur, which are schematised as such
Code: Select all
a u
a a u
ə a u
e aya ayu
i iya iyu
u uwa u
