Proto-North Caucasian: *ṭāqV ( ~ -ǝ̄-)
Meaning: a k. of vessel
Notes: It is hard to keep the PL form apart from the rest, although PL *-k- is quite irregular. This may be due to a contamination with another EC root, *tāḳwV (q.v.): indeed, the reflexes of the two roots are complementary distributed within Lezghian: *ṭak(a) is present in Ag., Rut. and Kryz., *taḳʷ(a) - in Lezg., Tab. and Bud. Otherwise (besides the easily explicable assimilative glottalisation in Ub.) all correspondences are regular, and the etymology seems reliable.
