Comments: Cf. also Akhv. Tlan., Ratl. =ac:i-q̇a-. The first part of the compound is *=oc:i- 'brother/sister'. In Avar there also exists another compound: ím-ʕal 'uncle' (with im- 'father'), but the corresponding Andian forms are not attested.
The Avar forms (wac:ʕal,jac:ʕal) were widely borrowed into neighbouring languages: cf. And. wacʔal,jacʔal, Kar. wacʕal,jacʕal, God. wac:aʕal,jac:aʕal, Tsez., Gin., Bezht., Gunz. wacʕal,jacʕal. Old Tind. > Inkh. waccahaw,jaccahaj.
