Proto-Lezghian: *k:onc:Vl
Meaning: 1 threshhold 2 door-jamb, door-post 3 ladder
Lezghian: gürc:el 2
Tabasaran: gurzil 1
Agul: günzel 1
Rutul: rigmizal 2
Udi: k:ac:k:al 3
Comment: Cf. also Lezg. Khl. grc:al 'threshhold', Ag. Burk. k:urzal 'ladder' (this form and Lezg. gürc:el, grc:al reflect rather PL *g- than *k:-), Rut. Khniukh. rigizan 'door-post'. Rutul reflects a compound with rak (obl. rigi-) 'door' (*rig-gɨnzal with further non-phonetic transformations of the long compound). Ud. k:ac:k:al is probably a metathesis < *k:ac:Vl-ak: with a diminutive suffix.
