Upper Necaxa Totonac

Upper Necaxa Totonac is a native American language of central Mexico spoken by 3,400 people in and around four villages in the Necaxa River Valley in northern Puebla: Chicontla, Patla, Cacahuatlán, and San Pedro Tlaloantongo. Although speakers represent the majority of the adult population in Patla and Cacahuatlán, there are very few monolinguals and few if any children are currently learning the language as a mother tongue, and, as a consequence, the language must be considered severely endangered.
