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.
bright white star in constellation Leo, 1550s, Modern Latin, apparently first so-called by Copernicus, literally "little king," diminutive of rex "king" (from PIE root *reg- "move in a straight line," with derivatives meaning "to direct in a straight line," thus "to lead, rule"). Probably a translation of Basiliskos "little king," a Hellenistic Greek name for the star, mentioned in Geminos and Ptolemy (in the "Almagest," though elsewhere in his writings it is usually "the star on the heart of Leo"); perhaps a translation of Lugal "king," said to have been the star's Babylonian name. Klein holds it to be a corruption of Arabic rijl (al-asad) "paw of the lion" (compare Rigel).
