Patagonia

region at the southern extremity of South America, with -ia + Patagon, name given by Europeans to the Tehuelche people who inhabited the coasts of the region, sometimes said to mean literally "large-foot," from Spanish and Portuguese pata "paw, animal foot" (see patten) in reference to the people's llama-skin shoes. But elsewhere said to be from Patagon, name of a dog-headed monster in the prose romance "Amadís de Gaula" (1508) by Garci Ordóñez de Montalvo (which also might have yielded California). Related: Patagonian.
