Comments: Av. paradigm B (gozó-l,guz-bí). The vowel -o- in Cham. is not clear. Most Andian forms listed can be borrowed from Av. (but since correspondences are regular, it is hard to prove). The Av. form can also be the source of Lak. and Darg. dialectal forms with -z- (not -c:-): Lak. k:aza (existing together with k:ac:a), Darg. Chir. gaza etc.
