Proto-West-Caucasian: *ḱ:ʷac:(ʷ)V (~ǵʷ-)
Meaning: 1 shin 2 calf of leg
Abkhaz: a-š́argʷáć̌ ́
Ubykh: ʎa-ǵáca 2
Comments: The Abkh. and Ub. form are in perfect correspondence. In both cases there is a compound with PWC *ʎ́a 'foot' (in Abkh. also a connecting morpheme -r-). The second consonant can also be reconstructed as *-c(ʷ)-.
