Sequences are:

pw (mbw), lw (ndw), tw, tsw, chw, shw, sw, zw, zhw, nw, nyw, ŋw

All noun and verb roots begin with a consonant; initial vowels are necessarily prefixes. Only /a,ɨ/ occur in prefixes or at the beginning of words, and only /ə/ occurs in suffixes. /ɨ,y/ do not occur at the ends of words.

Vowels

Vowels

i	i
y	ʉ
ɛ	e
a	a
ɔ	o
u	u
ə	ə
ɨ	ɨ

All known long vowels may occur medially or at ends of words, none at the beginning, though long /ɛ,y/ are not attested. Long vowels are written double: aa, əə, ii, ‿ɨɨ, oo, uu. Diphthongs ie, iə, ʉə, ɨə, uə take a single tone.

Tones are high, mid, low, rising, falling. They are written as in IPA, apart from low, which is not written: á ā a ǎ â. Falling tone is largely confined to suffixes, and rising tone is rare, found only on a few nouns such as tǎ 'father'.
