Otomi language
Otomi (; Spanish: Otomí Spanish: [otoˈmi]) is a group of closely related indigenous languages of Mexico, spoken by approximately 240,000 indigenous Otomi people in the central altiplano region of Mexico. It belongs to the Oto-Pamean branch of the Oto-Manguean language family. It is a dialect continuum of closely related languages, because many of the varieties are not mutually intelligible. The word Hñähñu [hɲɑ̃hɲṹ] has been proposed as an endonym, but since it represents the usage of a single dialect it has not gained wide currency. Linguists have classified the modern dialects into three dialect areas: the Northwestern dialects spoken in Querétaro, Hidalgo and Guanajuato; the Southwestern dialects spoken in the State of Mexico; and the Eastern dialects spoken in the highlands of Veracruz, Puebla, and eastern Hidalgo and in villages in Tlaxcala and Mexico states.
Like all other Oto-Manguean languages, Otomi is a tonal language and most varieties distinguish three tones. Nouns are marked only for possessor; plural number is marked with a definite article and by a verbal suffix, and some dialects maintain dual number marking. There is no case marking. Verb morphology can be described as either fusional or agglutinating depending on the analysis. In verb inflection, infixation, consonant mutation, and apocope are prominent processes, and the number of irregular verbs is large. The grammatical subject in a sentence is cross-referenced by a class of morphemes that can be analysed as either proclitics or prefixes and which also mark for tense, aspect and mood. Verbs are inflected for either direct object or dative object (but not for both simultaneously) by suffixes. Grammar also distinguishes between inclusive 'we' and exclusive 'we'.
