Comment: Cf. also Lezg. pret. χa-na, imp. ruχuχ (with reduplication), Ag. Bursh. ruχa-s, Kryz. dur. ruχ-ri, imp. s-äχɨr. Different Ablaut grades are attested: *ʔiχʷa- in Ud. b-iχ-, with loss of *ʔi- in Lezg. χa-, Tab. χ-uz etc.; *ʔäχʷV- in Kryz. s=äχɨ-r; *ʔoχʷa- (originally probably a plural form - "to give birth (to many)") in most other forms.
An old derivate *ʔiχʷa-j > *χʷaj (a participial form) is reflected in Ud. χoj 'descendants', Lezg. χʷa, pl. r-uχʷa-jar (Khl. χʷa, r-uχʷa-jar) 'son'.
