Proto-Tupian language

Proto-Tupian (PT) is the reconstructed common ancestor of all the Tupian languages.

In Brazil, Tupian historical-comparative studies are being developed mainly by two scientific teams: one from the Laboratório de Línguas Indígenas (LALI) of the University of Brasília, under the coordination of Aryon Rodrigues; and the other one from the Museu Paraense Emílio Goeldi, located in Belém, under the orientation of Denny Moore.

These studies provide evidence about the Proto-Tupian economy and culture, suggesting, for example, that they had agriculture.

There are currently 70 Tupian languages, including Tupi, Paraguayan Guarani, Awetï, Ayvu, etc.

O'Hagan (2014)[2] proposes that Proto-Tupi-Guarani was spoken in the region of the lower Tocantins and Xingu Rivers.
