Comment: Cf. also Lezg. Khl. č̣u-d, Tab. Düb. hurč̣u-w, Ag. Bursh. jerč̣̌u-r, Fit. jerḳü-d, Burk. jerč̣uI-d. The resonant -r- before the hushing -č̣- in Tab. and Ag. points to PL *-l- (PL *-r- would have remained in all languages except Udi). Pharyngealization in Ag. (also in Tsakhur in the latest MSU recordings: juIč̣u-lle) may be archaic (a trace of the old laryngeal). Arch. č̣ʷi 'ninety' < *č̣iwi < (with metathesis) *u_ilč̣ʷɨ-j.
