Proto-Lezghian: *c̣:ämk / *kämc̣:
Meaning: 1 feather, down 2 goat skin, goat wool
Lezghian: c̣akul 1
Tabasaran: zikw 1
Archi: ḳenc̣ 2
Comment: The Lezg. and Tab. forms point to *c̣: in PL (conf. the correspondence Lezg. lit. c̣ak-ul : Khl. ckʷal without glottalisation, and the Tab. Kand. form c:ikʷ). Archi also has c̣: (cf. the erg. ḳenc̣:i, pl. ḳenc̣:-um) which is a strong point in favour of the comparison (inspite of the rather frequent metathesis). The Inlaut nasal must have been labial (to account for its loss in Tab. and lesg. - the dental would have been preserved - and the compensating labialisation of the velar).
