PROTO: *=olχwV̆r
MEANING: to defecate
COMMENT: An Av.-And.-Lezg. isogloss. The comparison is rather probable, but needs several phonetic comments. *-l- in PL (unambiguously established on basis of Ag., Tsakh. -r-) corresponds directly to -n- in the PA derivate *ʔinχ:u, thus it must be reconstructed for PEC. However, in PA we should expect a weakened reflex *-χ-, not *-χ:- after a medial liquid. The reason of the irregularity is probably an early loss of *-l- in the verbal stem (where all Andian languages and Av. reflect a pure stem *=iχ:-) and the consequent strengthening -χ- > -χ:- in the intervocalic position. Strong *-χ:- in *ʔinχ:u is obviously a result of later analogy with *=iχ:-.
