Etymology: Onychogryposis is a medical term built from Greek roots: "onyx" (nail) and "grypos" (curved, hooked, as in "grypos" meaning hook-nosed or curved). Together they describe a nail that has grown abnormally curved, like a claw. The Greek "onyx" is the same word that gave English "onyx," the banded stone, which was named for its resemblance to fingernails. The term is a modern coinage rather than an ancient one. Greek physicians of antiquity had no need for it, and it was formed in the 19th century from classical elements, the usual route for medical vocabulary of that period. Its formation follows a familiar pattern: a Greek combining form for the body part, paired with a root describing the deformity.
