Proto-West-Caucasian: *Pc̣V
Meaning: 1 to go sour, to curdle (of milk) 2 raw
Adyghe: ṗc̣a-n
Kabardian: ṗc̣a-n
Comments: PAK *ṗc̣a. The WC etymology of Shagirov (2,50-51: comparison with Ub. baćǝ- 'to become thick') seems dubious for both semantic and phonetic reasons. Since the EC counterpart of the root means both 'sour' and 'raw' (a natural and frequent semantic correlation), it seems possible to compare also (with a secondary loss of initial labial) PAK *c̣ǝ-ná (Ad., Kab. c̣ǝna) 'raw' (also borrowed in Ub.: c̣ǝna id., see Shagirov 2, 126).
