Other comments: There are about 380 Poyanáwa lived in the upper part of Môa river, Mâncio Lima, State of Acre, North of Brazil in 1990's. However, the language became extinct when the last known speakers likely survived into the first decade of the 2000s.   Poyanáwa people only has four numerals. After four, they say ''rũbakuĩsi'', which means ''many or much''.
