Proto-North Caucasian: *hćărnū
Meaning: stone
Notes: It seems probable that the Lak. word is related to Av.-And.-Tsez., although to explain it one needs to propose an extremely complicated reconstruction (*hćărnū) with a rather unique root structure (*HCVRRV). If the Lak. word is to be kept apart, the reconstruction will be simplier: *hănćū, and the etymology will be an Av.-And.-Tsezian isogloss.
