Cf. Ugr. ḳrd ‘hero, powerful one’ (Kogan 2015: 337)
There is no reliable cognate for Akk.-Ugr. *ḳrd ‘to be heroic.’ Arb. qdr ‘to have power or ability to do something’ (Lane 2495) could perhaps be compared (with metathesis). Also of interest is Tna. ḳärrädä ‘to refuse to agree or listen; to be stubborn, to argue, to persist in wanting to overcome someone; to be rival, to quarrel with each other’ (TED 949).
