the Brazil-Suriname border in the Northern Amazonia region by
about 2,100. It is spoken by people of all ages, including
children, and perhaps half of speakers are monolingual in
Tiriyó. Tiriyó speakers live along the Palumeu,
Tapanahoni and Sipaliwini rivers.
Tiriyó belongs to the Taranoan group of the Guianan sub-branch
of the Cariban language family. Closely related languages include
