Chamacoco is a Zamucoan language spoken in Paraguay by the Chamacoco people. It is also known as Xamicoco or Xamacoco, although the tribe itself prefers the name Ishír and sometimes Jewyo. When the term Ishiro is used to refer to the language, it is an abbreviation for Ishir(o) ahwoso, literally meaning 'the words, the language of the Chamacoco people'. It is spoken by a traditionally hunter-gatherer society that now practices agriculture. Its speakers are of all ages, and generally speak Spanish or Guarani as second and third languages.
