Iñapari language

Iñapari is a critically endangered indigenous South American language spoken by just four people in Peru along the Las Piedras river near the mouth of the Sabaluyoq river. The language is already extinct in neighboring Bolivia. All five remaining speakers are bilingual in Spanish and none of their children and grandchildren speak the language, which will likely lead to its extinction once the speakers die. The Iñapari language currently has a published dictionary.

The Pacaguara (Pacahuara) dialect described by Mercier was at least ethnically distinct. (But see Pacaguara language.)
