Tupi-Sprache
Before the first Portuguese explorers arrived in 1500, what is now Brazil was inhabited by several Amerindian peoples that spoke many different languages. According to Aryon Dall'Igna Rodrigues there were six million Indians in Brazil speaking over 1,000 different languages. When the Portuguese settlers arrived, they encountered the Tupi people, who dominated most of the Brazilian coast and spoke a set of closely related languages. The Tupi called the non-Tupi peoples "Tapuias", a designation that the Portuguese adopted; however, there was little unity among the diverse Tapuia tribes other than their not being Tupi. In the first two centuries of colonization, a language based on Tupian languages known as Língua Geral ("General Language") was widely spoken in the colony, not only by the Amerindians, but also by the Portuguese settlers, the Africans and their descendants. This language was spoken in a vast area from São Paulo to Maranhão, as an informal language for domestic use, while Portuguese was the language used for public purposes. Língua Geral was spread by the Jesuit missionaries and Bandeirantes to other areas of Brazil where the Tupi language was not spoken. In 1775, Marquis of Pombal prohibited the use of Língua Geral or any other indigenous language in Brazil. However, as late as the 1940s, Língua Geral was widely spoken in some Northern Amazonian areas where the Tupi people were not present.
