Nivaclé language

Nivaclé is a Matacoan language spoken in Paraguay and in Argentina by the Nivaclé. It is also known as Chulupí and Ashluslay, and in older sources has been called Ashluslé, Suhin, Sujín, Chunupí, Churupí, Choropí, and other variant spellings of these names. Nivaclé speakers are found in the Chaco, in Paraguay in Presidente Hayes Department, and Boquerón Department, and in Argentina in Salta Province.

Nivaclé is complex both in its phonology and morphology. Much of what is handled in syntactic constructions in many other languages is signalled in Nivaclé by its rich bound morphology and clitics. Nivaclé has several linguistic traits that are rare elsewhere in the world or even unique.
