Old English clawu, earlier clea, "claw, talon, iron hook," from Proto-Germanic *klawo (cf. Old Frisian klawe "claw, hoe," Middle Dutch klouwe, Dutch klauw, Old High German klawa, German Klaue "claw").
Claw-foot in reference to furniture is from 1823; claw-and-ball attested from 1893. Claw-hammer attested from 1769.
Old English clawian "to scratch, claw," from the same root as claw (n.). Related: Clawed; clawing. Cf. Dutch klaauwen, Old High German klawan, German klauen. To claw back"regain by great effort" is from 1953; as a noun, an act of this, from 1969.
narrow, arched structure that curves downward from the end of the digit in birds, reptiles, many mammals, and some amphibians. It is a hardened (keratinized) modification of the epidermis. Claws may be adapted for scratching, clutching, digging, or climbing. By analogy, the appendages of other lower animals are frequently called claws. The claw's shape is ordinarily suited to the food-getting habit of the animal. Eagles have long, curved talons for grasping prey; the claws of chickens are short and sturdy, for scratching the ground for food.
