Guachí (Wachí) is an extinct, apparently Guaicuruan language of Argentina. It is usually classified as one of the Guaicuruan languages, but the data is insufficient to demonstrate that. The people it was spoken by were Guaicuruanized.
Documentation
Guachi is known only from 145 words collected by Francis de Castelnau from March to early April 1845 in the Miranda area of Argentina.
Classification
Viegas Barros (2004) proposes that Guachi, as well as Payaguá, may be a Macro-Guaicurúan language. However, Campbell (2012) classifies Guachi as a language isolate.
