The Wichí languages are an indigenous Linguistic communication family spoken by the Wichí in northwestern Argentina together with far-southeastern Bolivia, part of the Matacoan family. They are also so-called as Mataco, Wichi, Wichí Lhamtés, Weenhayek, Noctenes, Matahuayo, Matako, Weʃwo. The create Mataco is common but pejorative.
Currently, the Argentine government does not earn education in indigenous languages in schools. Because the Wichí have to be fluent in Spanish to access government services, & children are only educated in Spanish, Wichí children only speak Spanish among themselves. This has presented all Wichí dialects vulnerable to extinction.
In 2010, the province of Chaco in Argentina declared Wichí as one of four provincial official languages alongside Spanish and the indigenous Moqoit and Qom.
