Comment: The verbal stem is preserved only in Tsakh. and Archi (cf. also Arch. dur. =eIrč:u-r pointing to labialisation in PL). Most other languages reflect only the derivate *ʡelč:ʷana 'whetstone' (in Lezg. with a secondary -j-suffixation: k:ünü < *ʡe(l)č:ʷanVj); besides the forms cited cf. also Tab. Kand. ilǯ̌an, Düb. hilǯ̌an, Ag. Bursh. ʕulǯem, Burk. ʡülǯan, Fit. ħurǯin, Tsakh. wɨžena (Gelm. wužana). Other derivates are: Rut. uǯud < *ʡeč:ʷV-t:V; Arch. čun 'knitting needle' < *(ʡi)č:ʷV-nV.
The medial *-l- in *ʡelč:ʷana must be probably explained from *-r-, having penetrated here from the verbal durative stem (cf. Arch. =eIrč:u-r) and modified to *-l- under the influence of the following nasal (a usual development, especially in verbal paradigms).
