Note that nasals match the position of any stops of other nasals that follow them, and consonants can be geminated intervocially.
The large fricative inventory was quite unstable, and collapsed in both Proto-Onpotcor and Proto-Qhalqon, but in different ways.
Vowels become lax in open syllables, but not when followed by geminates, as follows: a becomes [ə], e becomes [ɛ], i becomes [ɪ], o becomes [ɔ], u becomes [ʊ]. This only occurs to the second vowel in a diphthong.
The Proto-Onpotcor-Qhalqon language has the following diphthongs:
- ae [ae]
- ai [ai]
- ao [ao]
- ea [ea]
- ia [ia]
- io [io]
- ou [ou]
- ua [ua]
- ue [ue]
- ui [ui]
