Proto-Tḷantali language

A-mutation
Low vowels /æ æː ɑ ɑː/ are causing a vowel mutation, in which high vowels /i iː ɯ ɯː u uː/ are lowering to middle counterparts /e̞ e̞ː ɤ̞ ɤ̞ː o̞ o̞ː/ before syllable containing low vowels.

Phonotactics
(C)V(ː)(C)

C = any consonant V = any short vowel Vː = any long vowel

Accent
First syllable for singular number, last syllable for plural. Words may have only one stress.
