Ava Guarani language

Chiripá Guaraní, also known as Ava Guaraní and Nhandéva, is a Guaraní language spoken in Paraguay, Brazil, and also Argentina. Nhandéva is closely connected to Mbyá Guaraní, as intermarriage between speakers of the two languages is common. Speakers of Nhandéva and Mbyá generally live in mountainous areas of the Atlantic Forest, from eastern Paraguay through Misiones Province of Argentina to the southern Brazilian states of Paraná, Santa Catarina, and Rio Grande do Sul. There are approximately 4,900 speakers in Brazil and 7,000 in Paraguay.
