 Amerindian peoples of the pampas, such as the Puelche, Pehuenche, and Tehuelche, adopted the Mapudungun language as their main language (both of their names are in Mapudungun).Together with Quechua, Aymara, Guarani, and Nahuatl, Mapudungun was among the few Amerindian languages that expanded in use on the continents after the beginning of European colonization.This area of the Patagonia was generally isolated from European settlement until late in the 19th century.
