Uru–Chipaya languages
The Uru–Chipaya family is an indigenous language family of Bolivia.
The speakers were originally fishermen on the shores of Lake Titicaca, Lake Poopó, and the Desaguadero River.
Chipaya has over a thousand speakers and sees vigorous use in the native community, but all other Uru languages or dialects are extinct.
Loukotka also lists the Chango language, once spoken on the coast of Chile from Huasco to Cobija in Antofagasta Province. According to Loukotka that population would have been Araucanized at some point in history. More modern classifications leave it unclassified, as only proper names and placenames are known.
