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.: "Desde un punto de vista de la tipología morfológica clásica greenbergiana el otomí es una lengua fusional que se convertiría, por otro lado en aglutinante si todos los clíticos se reanalizaran como afijos (From the point of view of the classic Greenbergian morphological typologogy, Otomí is a fusional language which would however turn into an agglutinating one if all the clitics were reanalyzed as affixes)" 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 mark 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.See the individual articles for the forms used in each 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 . 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 c. 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.In most modern varieties of Otomi the name for "Mexico" has changed to (in Ixtenco Otomi) or (in Mezquital Otomi). In some varieties of Highland Otomi it is mbôndo. Only Tilapa Otomi and Acazulco Otomi preserve the original pronunciation (Lastra, 2006:47).

Colonial period and Classical Otomi

At the time of the Spanish conquest of central Mexico, Otomi had a much wider distribution than now, with sizeable Otomi speaking areas existing in the modern states of Jalisco (see Otomi language (Jalisco)) and Michoacán. After the conquest, the Otomi people experienced a period of geographical expansion as the Spaniards employed Otomi warriors in their expeditions of conquest into northern Mexico. During and after the Mixtón rebellion, in which Otomi warriors fought for the Spanish, Otomis settled areas in Querétaro (where they founded the city of Querétaro) and Guanajuato which previously had been inhabited by nomadic Chichimecs. Because Spanish colonial historians such as Bernardino de Sahagún used primarily Nahua speakers primarily as sources for their histories of the colony, the Nahuas' negative image of the Otomi people was perpetuated throughout the colonial period. This tendency towards devaluing and stigmatizing the Otomi cultural identity relative to other Indigenous groups gave impetus to the process of language loss and mestizaje, as many Otomies opted to adopt the Spanish language and customs in search of social mobility.

"Classical Otomi" is the term used to define the Otomi spoken in the early centuries of colonial rule. This historical stage of the language was given Latin orthography and documented by Spanish friars who learned it in order to proselytize among the Otomi. Text in Classical Otomi is not readily comprehensible since the Spanish-speaking friars failed to differentiate the varied vowel and consonant phonemes used in Otomi. Friars and monks from the Spanish mendicant orders such as the Franciscans wrote Otomi grammars, the earliest of which is Friar Pedro de Cárceres's Arte de la lengua othomí , written perhaps as early as 1580, but not published until 1907. In 1605, Alonso de Urbano wrote a trilingual Spanish-Nahuatl-Otomi dictionary, which included a small set of grammatical notes about Otomi. The grammarian of Nahuatl, Horacio Carochi, has written a grammar of Otomi, but no copies have survived. He is the author of an anonymous dictionary of Otomi (manuscript 1640). In the latter half of the eighteenth century, an anonymous Jesuit priest wrote the grammar Luces del Otomi (which is, strictly speaking, not a grammar but a report on research about Otomi). Neve y Molina wrote a dictionary and a grammar. cf. in general Zimmermann 1997

During the colonial period, many Otomis learned to read and write their language. Consequently, a significant number of Otomi documents exist from the period, both secular and religious, the most well-known of which are the Codices of Huichapan and Jilotepec.The Huichapan Codex is reproduced and translated in . In the late colonial period and after independence, indigenous groups no longer had separate status. At that time, Otomi lost its status as a language of education, ending Classical Otomi period as a literary language. This led to a declining numbers of speakers of indigenous languages, as Indigenous groups throughout Mexico adopted the Spanish language and Mestizo cultural identities. Coupled with a policy of castellanización this led to a rapid decline of speakers of all indigenous languages including Otomi, during the early 20th century.

Decentralized government agencies were created and charged with promoting and protecting indigenous communities and languages; these include the National Commission for the Development of Indigenous Peoples (CDI) and the National Institute of Indigenous Languages (INALI). In particular, the federal Ley General de Derechos Lingüísticos de los Pueblos Indígenas ("General Law on the Language Rights of the Indigenous Peoples"), promulgated on 13 March 2003, recognizes all of Mexico's indigenous languages, including Otomi, as "national languages", and gave indigenous people the right to speak them in every sphere of public and private life.

Current speaker demography and vitality Currently, Otomi dialects are spoken by circa 239,000 speakers—some 5 to 6 percent of whom are monolingual—in widely scattered districts (see map). The highest concentration of speakers is found in the Valle de Mezquital region of Hidalgo and the southern portion of Querétaro. Some municipalities have concentrations of Otomi speakers as high as 60–70%. Because of recent migratory patterns, small populations of Otomi speakers can be found in new locations throughout Mexico and the United States. In the second half of the 20th century, speaker populations began to increase again, although at a slower pace than the general population. While absolute numbers of Otomi speakers continue to rise, their numbers relative to the Mexican population are falling.

Although Otomi is vigorous in some areas, with children acquiring the language through natural transmission (e.g. in the Mezquital valley and in the Highlands), it is an endangered language. Three dialects in particular have reached moribund status: those of Ixtenco (Tlaxcala state), Santiago Tilapa (Mexico state), and Cruz del Palmar (Guanajuato state). On the other hand, the level of monolingualism in Otomi is as high as 22.3% in Huehuetla, Hidalgo, and 13.1% in Texcatepec, Veracruz). Monolingualism is usually significantly higher among women than among men. Due to the politics from the 1920s to the 1980s that encouraged the "Hispanification" of indigenous communities and made Spanish the only language used in schools, no group of Otomi speakers today has general literacy in Otomi, while their literacy rate in Spanish remains far below the national average.33.5% of Otomi speakers are illiterate compared with national average of 8.5%

Classification

The Otomi languages belongs to the Oto-Pamean branch of the Oto-Manguean languages. Within Oto-Pamean, it is part of the Otomian subgroup, which also includes Mazahua.
