Proto-North Caucasian: *čwɨ̆rGwV (~-i-,-ā-)
Meaning: hole
Notes: Reconstructed for the PEC level. An expressive root with two stops - which explains the assimilation of the first consonant to the second in PC and PD.
We should also mention PL *č:ʷiq̇ 'buttock, anus' (Tab. ǯ̌uq̇, Ag. Fit., Burk. ǯuq̇) and Lak. cuq (pl. cuqa-l) 'hole' - they may be considered as irregular reflexes of the same expressive root.
/Consider also Av. šeq̇:ér, Chad. čuq̇:úr 'throat, larynx' [Av. > Akhv. šeq̇:e "Adam's apple", Gin. šeq̇er "gullet"]; Bezht. Tlad., Khosh. čäχrö 'furrow'./
