Proto-North Caucasian: *c̣EnχV(n)
Meaning: to search, ask
Notes: The cognateship of the EC and WC forms seems quite probable, although in PWC we must assume a secondary voicing (-χ- > -ʁ-). The PN form is metathesized: *χāṭṭ- < *χānc̣- < *c̣ānχ- (probably with a secondary length, because other languages suggest rather a short vowel). All these irregularities are explained by the exceptional root structure *CVRCV, very rare for verbs.
