Proto-West-Caucasian: *ḳǝ
Meaning: a morpheme denoting singularity
Abkhaz: -ḳ(ǝ)
Abaza: -ḳ(ǝ)
Ubykh: -ḳ́(ǝ)
Comments: PAT *-ḳǝ : here this morpheme is productive. It is used also within the numeral 'one' (Abkh. a-ḳǝ́, Abaz. za-ḳǝ). In Ub. it survived only within some forms like ca-ḳ́ǝ́ 'tooth' (*'a single tooth' = PAT *cǝ-ḳǝ) etc. In AK cf. perhaps Ad. -č̣́a 'deverbative abstract' (?)
