Proto-North Caucasian: *jalχa(-nV)
Meaning: whetstone, grindstone; saw
Notes: Reconstructed for the PEC level. Some features (reduction of the initial syllable in PA, Lak. b- /bajlaχ:i < *bV-jalχV/) suggest that the stem may be deverbal; the original verbal root, however, is not attested (cf. perhaps Inkh. χe- "to saw" - isolated within Tsezian?).
