Proto-North Caucasian: *č̣ü̆kwV / *č̣ü̆ḳwV
Meaning: to be hooked, curved; hook
Notes: An expressive common EC root. The original quality of the Inlaut consonant (*-k-) is probably retained in PL, and *-ḳ- in PN and PTs must be explained by assimilation; otherwise the correspondences are regular.
Abayev (1958, 295) proposes a Caucasian origin for Osset. cäg 'ring, chain link'.
