Proto-West-Caucasian: *c̣ʷa (/*cʷa)
Meaning: 1 star 2 sky
Abkhaz: á-ječ̣̌a 1
Abaza: jač̣ʷa 1
Adyghe: wā-ša 2
Kabardian: wā-fa 2
Ubykh: c̣wa(n)ḳ́ 1
Comments: PAT *ja-c̣ʷa; Ub. c̣ʷa(n)-ḳ́ with the old singulative suffix *-ḳǝ (q.v.). Vogt lists also the variant jacʷa (with secondary loss of glottalisation). In PAK the roots 'star' and 'sky' (*zʷA q.v.) had "changed places": *-sʷa (going back to *cʷa with loss of glottalization like in Ub.) meant originally 'star', but lost this meaning in the compound *wa-sʷá (where *wa- means 'sky' by itself, see *wa).
