Iskonawa language
Isconahua or Iscobaquebo is an indigenous American language of the Panoan family. It is spoken by the Isconahua tribe in Peru. The Isconahua is a very isolated tribe and has very little contact with the outside world. In spite of this, the language is spoken by only one person, as of 2023, when language preservation efforts were underway.
It has an official alphabet approved by the Ministry of Education of Peru.
