Proto-West-Caucasian: *č̣́ʷǝ (/*č́ʷǝ)
Meaning: cold
Adyghe: čǝʡa
Kabardian: ṣ́ǝʡa
Ubykh: č́ǝ
Comments: PAK *č̣ǝ-ʡá (in Ad. a secondary dissimilative deglottalisation). It is harder to account for deglottalisation in Ub.; in any case, the PAK and Ub. forms are obviously related. Cf. also Ub. impers. a-č́ǝ́ 'it is cold'. Despite Shagirov (2, 154) PAK *č̣́ǝ 'winter' .and. *ṗǝč̣́a- 'to freeze' should be strictly kept apart from this root (they have a different root consonant); PAT *c̣ǝʕa / *c̣ǝħa 'ice' also should be separated (the PAT *c̣ : PAK *č̣ correspondence does not exist).
