Proto-Lezghian: *čʷɨ-χ[a]r
Meaning: 1 (first) cousin 2 step-father
Agul: čum-χar 1
Rutul: čuχud-did 2
Archi: še-ker-t:u 1
Comment: Cf. also Ag. Bursh. čaχʷar 'first cousin'. The Rut. (Shinaz) form is cited from Ibragimov, who has recorded there: čuχu-d-did 'stepfather', čurχu-d-nin 'stepmother' - historically "father (did) or mother (nin) of the first cousin (*čʷɨ-χ[a]r)". The first component of this kinship term (Rut. Shin. ču-, Ag. ču-, Arch. še-) can be easily identified with *čʷɨj 'brother', and the word as a whole - with forms like Darg. uzi-q̇ar, Av. wac:-ʕal etc.
The Archi form (šeker-) very likely belongs here to, but the irregular change *-χ- ( < *-q-) to -k- is baffling.
