Cacán language

Extinct language of northern Argentina and Chile

Cacán is an extinct language that was spoken by the Diaguita and Calchaquí tribes in northern Argentina and Chile. It became extinct during the late 17th century or early 18th century. The language was documented by the Jesuit Alonso de Bárcena, but the manuscript is lost. Genetic affiliation of the language remains unclear, and due to the extremely limited number of known words, it has not been possible to conclusively link it to any existing language family.
