Oti language

The Otí language, also known as Chavante or Euchavante, is a language isolate once spoken in the state of São Paulo, Brazil, between the Peixe and Pardo rivers. The language became extinct at the beginning of the 20th century. Only a few wordlists are preserved, and Campbell leaves it unclassified due to a paucity of information.

Greenberg classified Oti as a Macro-Ge language, but he provided almost no supporting data and has not been followed by other researchers.
