Comments: If the BZK form is archaic (okotz < *o=koc?), the form kokotz/ts seems to be blended with *kokot ‘nape’ (q.v.), of distinct origin. Alternatively the reduplicated *kokoc (or *kokoć) was original, with dissimilation in BZK. This body part term may be related to Bsq *a=kać, *ma=keć ‘notch, nick’ (q.v., cf. Lezgi q̇ac̣ ‘notch, nick’ vs. Rutul, Tsakhur q̇ac̣ ‘chin’).
