If you travel to Argentina, you may have a chance to visit the pampas, the fertile lowlands that cover part of South America.
This noun is of American Spanish origin and ultimately from Quechua in the central Andes mountains in South America. Argentina is the country that is home to more pampas (treeless, grassy plains) than any other. The pampas may seem rather empty without the occasional gaucho, a cowboy of the pampas, and yet another word of South American Spanish origin.
