Otomi language

Otomi is a group of closely related varieties in the Oto-Pamean branch of the Oto-Manguean language family, spoken by roughly 240,000 to 300,000 indigenous Otomi people across the central altiplano of Mexico, including the states of Hidalgo, Querétaro and the State of Mexico. Linguists divide Otomi into northwestern, southwestern and eastern regional groupings comprising nine distinct varieties, many of which are not mutually intelligible, and three of these varieties are considered moribund. Mexico granted Otomi official recognition as a national language in 2003 under the General Law of Linguistic Rights of Indigenous Peoples, giving it some legal protection despite its ongoing endangerment.
