Proto-North Caucasian: *q̇ar[H]V
Meaning: cousin, first cousin
Notes: Reconstructed for the PEC level. The root occurs only in compounds (primarily with *=ɨ̆ć_ĭ 'brother /sister', but in Avaro-Andian languages also with some other kinship terms), which has made the correspondences not quite regular. The major irregularity is loss of glottalisation in Lak. (-qu) and PL (*-χ[a]r). Still, the complete parallelism of the components and the exact semantic match of reflexes make the etymology quite probable.
