Yine is the principle variety of Piro, which is a Maipurean language spoken in Peru.
It belongs to the Piro group which also includes the nearly extinct Iñapari and Apurinã.
The Manchineri who live in Brazil (Acre) and reportedly also in Bolivia speak what may be a dialect of Yine (Aikhenvald, Kaufman).
[2] This language is also called Contaquiro, Pira, Piro, Pirro, Simiranch, or Simirinche.
They live in the Ucayali and Cusco Departments, near the Ucayali River, and near the Madre de Dios River in the Madre de Dios Region in Peru.
