Proto-West-Caucasian: *sʷǝ
Meaning: 1 to get cold, freeze 2 heap of snow
Abkhaz: a-š̌-rá 1
Abaza: šʷ-ra 1
Ubykh: sʷǝ-bIǝ́
Comments: PAT *sʷǝ (cf. also Bzyb. a-ś̌-rá). The Ub. word is a compound (for the second part see PWC *bIa), and an exact parallel of PAT *sʷǝ-bǝ "hoar-frost, caked snow" (Abkh. a-š̌ǝ́b, Abaz. šʷǝb). Therefore Dumézil's (1969) analysis of Ub. sʷǝ- as 'light, white' is certainly wrong. Despite Shagirov (1,194) PAT *sʷǝbǝ and Ub. sʷǝbIǝ́ for phonetic reasons can not be related to PAK *č:ápǝ 'hoar-frost'.
