An Etymological Dictionary of the German Language/Annotated/Kralle
Kralle, feminine, ‘claw, talon, clutch,’ Modern High German only; wanting in the earlier periods. Allied to Greek γράω, ‘to gnaw,’ Sanscrit root gras, ‘to devour’?. Middle High German krellen, ‘to scratch’ (Gothic *krazljan?), is more closely connected.
