Av. paradigm A (ʕín-zul, ʕún-dul; Chad. ʕín-dul, ʕína-l). In PA we have a suffixed form *ħan-di (reflected directly in Akhv. and Cham.); other languages, however, reflect the further diminutive suffixation *ħandi-ḳa (cf. Kar. Tok. handiḳ́a) with assimilation *-d- > -ṭ- in most languages. With a privative suffix the root is present in a derivate *ħan-q̇:V- / *ħandi-q̇:V- 'deaf': Av. ʕínq̇:a-, Chad. ʕínq̇:a-, Cham. Gig. hãq̇:u-l, Akhv. hãdeloq̇:e-, Tind. handiq̇:u-. Av. > Bezht. Tlad., Gunz. ʕenq̇ab, Bezht. Khosh. enq̇ab, perhaps also Arch. eInk-du (although the Archi velar is rather strange).
Finally, the same root is present in the compound Av. ʕen-ék:- = And. an-č:i-, Tind. an-ix́:- 'to listen' ("ear" + "catch, hold"; Cham. Gig. ʕenax-id- id. should be rather considered as borrowed from Avar, as well as Bezht. Tlad. ʕenekzi =aq- id.).
