Proto-North Caucasian: *kVmś_wV
Meaning: door-mat, floor-cloth
Notes: A cultural And.-Lezg. isogloss (in And. we have to suppose a metathesis *kars:am < *kams:-ar). We can also mention some similar, but phonetically irregular, forms: Bezht. (Tlad., Khosh.) kiz 'carpet'; Chech. kuz, Ing. ḳuws id. (correspondences between Chech. and Ing. are irregular). The PEC antiquity and phonetic details are rather unclear.
