Proto-North Caucasian: *ḳĂ
Meaning: a suffix(diminutive or singulative)
Proto-Avaro-Andian: *-ḳV Proto-West Caucasian: *ḳǝ Notes: One of the very rare class of derivative suffixes, reconstructable for PNC; cf. also Hurr. -ga, -gǝ id. The morpheme is expressive, thus correspondences are not quite regular (sometimes glottalisation disappears). The suffix is still productive in Nakh and Abkh.-Abaz., but it has left numerous traces in other languages (including Tsezian and Dargwa).
