Proto-Tupian


Proto-Tupian is the reconstructed common ancestor of all the Tupian languages. It consists, therefore, of a hypothetic language, reconstructed by the comparative method from data of the descendant languages.
In Brazil, Tupian historical-comparative studies are being developed mainly by two scientific teams: one from the Laboratório de Línguas Indígenas 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. The studies are provide evidence about the Proto-Tupian economy and culture, suggesting, for example, that they had agriculture.
The most accepted theory is that the Tupian language family was originated between the Guaporé and Aripuanã rivers, in the Madeira River basin. There are currently 70 Tupian languages, including Tupi, Paraguayan Guarani, Awetï, Ayvu, etc.

Homeland and ''Urheimat''

Rodrigues considers the Proto-Tupian Urheimat to be somewhere between the Guaporé and Aripuanã rivers, in the Madeira River basin. Much of this area corresponds to the modern-day state of Rondônia, Brazil. 5 of the 10 Tupian branches are found in this area, as well as some Tupi–Guarani languages, making it the probable urheimat of these languages and maybe of its speaking peoples. Rodrigues believes that Proto-Tupian dates back to around 5,000 B.P.
O'Hagan proposes that Proto-Tupi-Guarani was spoken in the region of the lower Tocantins and Xingu Rivers. Proto-Omagua-Kokama then expanded up the Amazon River, Proto-Tupinamba expanded south along the Atlantic coast, and the Southern branch expanded up along the Tocantins/Araguaia River towards the Paraná River basin.

Lexicon

This section lists Proto-Tupían reconstructions from Rodrigues and Cabral. Since the reconstructions are highly tentative, the Proto-Tupían forms are all marked by two asterisks.
