Cayubaba

Cayubaba is the language of the Cayubaba people of the Bolivian Amazon, who live west of the Mamoré River in the Beni lowlands, within the floodplain country historically known as Moxos. No genetic relationship to any other language has been established, so it is classed as an isolate.

The first European to reach them was the Jesuit Agustín Zapata in 1693, who found seven large villages in their territory; early in the eighteenth century another Jesuit, Antonio Garriga, founded the Exaltación mission among them, followed by the missions of San Carlos, Concepción and Peñas.
