Proto-North Caucasian: *gɨ[r]ʒ́wV
Meaning: noodles
Notes: A Nakh-Lezg. isogloss. Since the meaning coincides precisely in Nakh and some Lezg. languages (Bud.), we think that the comparison is valid and the original meaning was 'noodles', or at least some kind of food rising to the surface after boiling; hence the meaning 'sour cream' (usually connected with 'top', 'surface') in Tsakh., and the later development > 'bark' in other Lezg. languages.
The PL form has a suffix *-la; medial *-r- was probably lost as a result of dissimilation.
