Uto-Aztecan languages
Tarahumara was previously considered to belong to the Taracahitic group of the Uto-Aztecan languages, but this grouping is no longer considered valid. It is now grouped in a Tarahumaran group along with its closest linguistic relative, the Guarijío language (Varihio, Huarijío), which is also spoken in the Sierra Madre Occidental.
