Proto-Lezghian: *t:alc̣:
Meaning: 1 butter 2 fat
Lezghian: düd-ʁʷer 1
Tabasaran: darc: 2
Agul: darc: 2 (Fit.)
Rutul: dad-ʁIʷar 1
Comment: Cf. also Lezg. Akht. t:üd-ʁʷer, Khl. ṭʷed-ʁʷaIr (labialisation in the Lezg. reflex is secondary, due to the labialising influence of ʁʷ). The Lezg. and Rut. forms are compounds with PL *χ:IarV 'butter' q.v., and thus go back to *t:alc̣[u]-χI:ar; the first component corresponds to Tab. and Ag. darc: perfectly well. Medial *-l- is reconstructed on basis of Tab./Ag. forms (original *-r- would remain in Lezg. and Rut.).
