Yine [ˈjine] (previously known as Piro, ISO 639-3 = pib) is a Maipuran language (Payne 1991, Campbell 1997, Solís Fonseca 2003). See Payne (1991) and Campbell (1997) for discussion of the relationship of the Maipuran (or Maipurean) languages to the controversial Arawakan stock. There are approximately 3,000 speakers of Yine in the Peruvian Amazon. People in Brazil and Bolivia known as Manchineri (alternative spellings exist; ISO 639-3 = mpd) also speak a dialect of Yine (Urquía Sebastián 2006a).
