Kagwahiva language
Kawahiva is a Tupi–Guarani dialect cluster of Brazil. The major variety is Tenharin.
The Tenharim, Parintintín, Amondawa, Uru-eu-wau-wau and Júma peoples, along with a recently contacted group confusingly labeled "Karipuná" in the literature, all call themselves Kavahiva. Their speech is all very similar, and also similar with other languages now extinct. Apiaká is very similar and may be a dialect.Phonology
