The Nheengatu language (Tupi: ), often spelled Nhengatu, is an Amerindian language of the Tupi–Guarani family. It is also known by the Portuguese names língua geral da Amazônia and língua geral amazônica, both meaning "Amazonian general language", or even by the Latin lingua brasilica (Brazilian language). Nheengatu originated in northern Brazil in the 17th century as a lingua franca. Now known as nheengatu (also nhengatu, nyengatú, língua geral, geral, yeral), it is still spoken along the Rio Negro in northern Brazil (as well as in neighboring Colombia and Venezuela).
