Tremembé language

Tremembé a.k.a. Teremembé is an extinct and unattested language of Brazil. It was originally spoken by the Tremembé people, who once inhabited the northern Brazilian coasts from Pará to Ceará. The Tremembé were described as a "Tapuia" tribe - that is, not one of the dominant Tupi–Guarani peoples of the coasts.
