Aymara language
"Salar" means salt flat in Spanish. "Uyuni" originates from the Aymara language and means a pen (enclosure); Uyuni is a surname and the name of a town that serves as a gateway for tourists visiting the Salar. Thus "Salar de Uyuni" can be loosely translated as a salt flat with enclosures, the latter possibly referring to the "islands" of the Salar; or as "salt-flat at Uyuni (the town named 'pen for animals')".
