Otomi ( ; ) is an Oto-Pamean language spoken by approximately 240,000 indigenous Otomi people in the central altiplano region of Mexico. Otomi consists of several closely related languages, many of which are not mutually intelligible. The word Hñähñu 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 are spoken in Querétaro, Hidalgo and Guanajuato; the Southwestern dialects are spoken in the State of Mexico; and the Eastern dialects are spoken in the highlands of Veracruz, Puebla, and eastern Hidalgo and 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; the plural number is marked with a definite article and a verbal suffix, and some dialects keep dual number marking. There is no case marking. Verb morphology is either fusional or agglutinating depending on the analysis. In verb inflection, infixation, consonant mutation, and apocope are prominent processes. The number of irregular verbs is large. A class of morphemes cross-references the grammatical subject in a sentence. These morphemes can be analysed as either proclitics or prefixes and marks 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'.
After the Spanish conquest, Otomi became a written language when friars taught the Otomi to write the language using the Latin script; colonial period's written language is often called Classical Otomi. Several codices and grammars were composed in Classical Otomi. A negative stereotype of the Otomi promoted by the Nahuas and perpetuated by the Spanish resulted in a loss of status for the Otomi, who began to abandon their language in favor of Spanish. The attitude of the larger world toward the Otomi language started to change in 2003 when Otomi was granted recognition as a national language under Mexican law together with 61 other indigenous languages.
Name
Otomi comes from the Nahuatl word otomitl, which in turn possibly derived from an older word, totomitl "shooter of birds." It is an exonym; the Otomi refer to their language as Hñähñú, Hñähño, Hñotho, Hñähü, Hñätho, Hyųhų, Yųhmų, Ñųhų, Ñǫthǫ, or Ñañhų, depending on the dialect. Most of those forms are composed of two morphemes, meaning "speak" and "well" respectively.
The word Otomi entered the Spanish language through Nahuatl and describes the larger Otomi macroethnic group and the dialect continuum. From Spanish, the word Otomi has become entrenched in the linguistic and anthropological literature. Among linguists, the suggestion has been made to change the academic designation from Otomi to Hñähñú, the endonym used by the Otomi of the Mezquital Valley; however, no common endonym exists for all dialects of the language.
History
Proto-Otomi period and later precolonial period
The Oto-Pamean languages are thought to have split from the other Oto-Manguean languages around 3500 BC. Within the Otomian branch, Proto-Otomi seems to have split from Proto-Mazahua ca. 500 AD. Around 1000 AD, Proto-Otomi began diversifying into the modern Otomi varieties. Much of central Mexico was inhabited by speakers of the Oto-Pamean languages before the arrival of Nahuatl speakers; beyond this, the geographical distribution of the ancestral stages of most modern indigenous languages of Mexico, and their associations with various civilizations remain undetermined. It has been proposed that Proto-Otomi-Mazahua most likely was one of the languages spoken in Teotihuacan, the greatest Mesoamerican ceremonial center of the Classic period, the demise of which occurred ca. 600 AD.
The Precolumbian Otomi people did not have a fully developed writing system. However, Aztec writing, largely ideographic, could be read in Otomi as well as Nahuatl. The Otomi often translated names of places or rulers into Otomi rather than using the Nahuatl names. For example, the Nahuatl place name Tenochtitlān, "place of Opuntia cactus", was rendered as in proto-Otomi, with the same meaning.
