Matacoan

Matacoan is a language family historically spoken in the Gran Chaco region of South America, primarily in present-day Argentina and Paraguay. It is named after the Mataco people, who are the most prominent speakers of languages within this family. The family consists of a small number of closely related languages, with the most well-documented being Wichí (also known as Mataco), Chulupí (also known as Nivaclé), and Chorote. Other languages, such as Vejoz, are also sometimes included or considered dialects depending on the linguistic classification.

The languages of the Matacoan family share significant lexical and grammatical similarities, indicating a common ancestral origin. Linguistically, they are characterized by complex phonological systems, often including glottalized consonants, and a system of verb morphology that can be quite intricate. Noun morphology also shows distinct features, with pronominal prefixes being common.

Historically, the Matacoan peoples were semi-nomadic hunter-gatherers and horticulturalists, adapting to the challenging environment of the Gran Chaco. Their cultures and languages have been subject to significant influence from neighboring indigenous groups and, more recently, from the dominant Spanish-speaking societies.

In recent decades, the number of speakers for many Matacoan languages has declined due to assimilation and the pressure of dominant national languages. Efforts are underway by some communities and linguists to preserve and revitalize these languages, including documentation, language education programs, and the creation of written materials. The classification of Matacoan within broader South American language families remains a subject of ongoing research and debate among historical linguists.
