Fabre reports that the Kamëntšá are descended, at least in part, from the Quillasinga, whose language is unattested.

[2] Jolkesky notes that there are lexical similarities with the Choco languages due to contact.

[7] Huber & Reed, Howard, and O'Brien all analyze six vowel phonemes in Kamëntšá: /a/, /e/, /i/, /o/, /u/, and /ɨ/.

[7][8][9] O'Brien notes that /ɨ/ has a limited distribution and is rarely found at the beginnings of words,[10] and that [i] in many cases may be an allophone of /e/ before palatal consonants.
