Proto-Tsezian: *c̣ɔc̣ɔ- (~ a, -Ṽ-)
Meaning: glow-worm, firefly
Bezhta: c̣ac̣aka (Khaid.)
Comments: Attested only in Bezht., but having possible external parallels. The Bezht. word also means 'spark' and may in fact be a contamination of the present root with another one (cf. Gunz. c̣ǝḳǝ-ṭma 'fire-brand', see under PEC *c̣_wɨ̆jVkwŏ).
