Comments: Av. paradigm B or C (erg. icí-c:a); but Chad. A (gen. íši-l). This is one of the few cases of the correspondence Av. c : PA *s (reflecting earlier labialisation). The MSU recordings have -s:- in Tind. and Cham., which is obviously a mistake (to judge from external evidence). Cf. also Cham. Gig. resi,resila (misspelled in the MSU recordings as res:i,res:ila).
