Minority languages are spoken throughout the nation. One hundred and eighty Amerindian languages are spoken in remote areas and a significant number of other languages are spoken by immigrants and their descendants. In the municipality of São Gabriel da Cachoeira, Nheengatu (a currently endangered South American creole language – or an 'anti-creole', according to some linguists – with mostly Indigenous Brazilian languages lexicon and Portuguese-based grammar that, together with its southern relative língua geral paulista, once was a major lingua franca in Brazil, being replaced by Portuguese only after governmental prohibition led by major political changes), Baniwa and Tucano languages had been granted co-official status with Portuguese.
