Comment: Cf. also Lezg. erg. č:ep:e-di; Bud. č̣eb-iǯ 'rain'. Obl. base *č:äp:ɨ- (cf. Rut. ǯäba-, Tsakh. Gelm. ǯab, ǯabɨ-). 4th class in Rut. and Tsakh. In Arch. -ṗ- < *-p:- through assimilation; in some languages PL *č̣äIp: (through regressive assimilation) changed to *č:äIp:.
In Tab. we could possibly link (Düb.) č̣aIṗaI 'home-brewed alcoholic liquor' (perhaps with a pejorative meaning shift < 'dirt, slime'; cf. Arch. χ:aláj 'home-brewed liquor' derived from χ:al- 'bad').
