Tuxá language
Tuxá was the eastern Brazilian language of the Tuxá people, who now speak Portuguese and Dzubukuá. The language was believed to have ceased being spoken in the late 19th century, but in the 1960s a research team found two women that had been expelled from the Tuxa tribe in Bahia who knew some thirty words.
It was spoken along the São Francisco River near Glória, Bahia, and was reported by Loukotka to have more recently been in the village of Rodelas, Pernambuco.
