 Another theory points to the similarity of the valley of the Aconcagua with that of the Casma Valley in Peru, where there was a town and valley named "Chili".Other theories say Chile may derive its name from a Native American word meaning either "ends of the earth" or "sea gulls"; from the Mapuche word "chilli," which may mean "where the land ends;" or from the Quechua "chiri", "cold", or "tchili", meaning either "snow" or "the deepest point of the Earth".Another origin attributed to "chilli" is the onomatopoeic "cheele-cheele"—the Mapuche imitation of the warble of a bird locally known as trile.
