Proto-West-Caucasian: *cA
Meaning: 1 burn 2 hot
Abkhaz: a-cá 2
Adyghe: stǝ-n 1
Kabardian: sǝ-n 1
Ubykh: ca- 1,2
Comments: Cf. also Abkh. Bzyb. a-cá id. PAK *sǝ / *stǝ. The AK intransitive verb is rarely used; more frequent is the derivate Ad. ʁa-stǝ-n, Kab. ʁa-sǝ-n 'to burn'. Origins of Ad. -t- are not very clear (perhaps a contamination with pš́ta- 'to boil' - cf. Kab. pśtǝ-r 'hot' /derived from pśtǝ-n 'boil'/ along with sǝr 'burning, scorching' = Ad. stǝ-r 'hot; burning, scorching').
