Proto-West-Caucasian: *[ć̣]ǝʁa-
Meaning: to ask
Abkhaz: a-c̣ā-rá
Abaza: c̣ʕa-ra
Ubykh: ʒʁa-
Comments: PAT *ć̣ǝʕa- (cf. Bzyb. a-ć̣ā-rá); Ub. sǝ-ʒʁá-n. The word is obviously connected with EC forms like Av. c̣eχ:é-ze etc., thus a hissing Anlaut is probable for PWC. We may assume that Ub. ʒʁa- is a modification of *ʒ́ʁa- (since Ub. ʒ́ does not occur in any consonant clusters), which, in its turn, is assimilated from *ć̣(ǝ)ʁa-.
