The Monde languages of Brazil form a branch of the Tupian language family.
Cinta Larga is a dialect cluster spoken by a thousand people. Other languages are Mondé, Aruáshi, Suruí, Zoro, and Gavião do Jiparaná.
Internal classification of the Mondé languages according to Moore (2005):[1]
Unclassified: Arara do Guariba
Below is a list of Mondé language varieties listed by Loukotka (1968), including names of unattested varieties.[2]
Kabanae (spoken by the "Arara nation" according to Johann Natterer) and Matanau, are both extinct Monde languages that were spoken at the mouth of the Aripuanã River. Word lists of Kabanae and Matanau were collected by Johann Natterer in 1829 during his expedition into the Madeira River (Jolkesky 2016: 640-641).[3]
Jolkesky (2016) also observed some similarities between the Arara do Rio Branco and the Monde languages; however, Arara do Rio Branco remains unclassified.
