Proto-West-Caucasian: *ʎʷa

Abkhaz: a-jáša
Abaza: ra-jša
Adyghe: zā-fa
Kabardian: zā-xʷa
Ubykh: sʷa-x
Comments: PAT *jV-ša (with a pronominal or reciprocal prefix); PAK *za-xʷá (on the etymology of the first part see Shagirov 1, 204). The correspondence PAT *š : PAK *xʷ : Ub. sʷ points unambiguously to PWC *ʎʷ. Cf. also PAK *xʷá-da (Ad. fad, Kab. xʷada) 'similar, equal' (despite Dumézil 1932, 92; 1963, 14-15; Kuipers 1960, 113; Shagirov 2, 106 PAK *xʷa- here can hardly be analyzed as a version prefix; the semantic correlation 'straight' - 'similar, equal' is quite natural).
