Proto-North Caucasian: *Hč̣ōlV̄
Meaning: black
Notes: Reconstructed for the PEC level. One of the cases of exceptional preservation of a laryngeal in Av. (in the original *HCVCV structure). Since the stem has no class prefixes in PN, Av. and PL, the PA situation is probably secondary (the expected stem *č̣Vr- or *Hič̣Vr- began to have an adjectival inflection).
