Qatabanian

ḳny - to acquire (LIQ 147)

PWS
*ḳny - to acquire, to possess (Kogan 2015: 89)
While both standard Akkadian dictionaries display a verb ḳanû ‘to acquire’ (CAD Q 91, AHw. 898), there are weighty reasons to doubt that an autochthonous Akkadian lexeme with this meaning has ever existed. As for the numerous NA attestations (including the noun ḳinītu, Deller 1991), they are most probably to be explained by Aramaic influence
