Internal classification and reconstruction

A genetic relationship between Zapotecan and Mixtecan was first proposed by Orozco y Berra in 1864, he also included Cuicatec, Chocho and Amuzgo in his grouping. In 1865 Pimentel added Mazatec, Popoloca, Chatino and Chinantec – he also posed a separate group of Pame, Otomi and Mazahua, the beginning of the Oto-Pamean subbranch. Daniel Brinton's classification of 1891 added Matlatzinca and Chichimeca Jonaz to Pimentel's Oto-Pamean group (which wasn't known by that name then), and he reclassified some languages of the previously included languages of the Oaxacan group. In 1920 Lehmann included the Chiapanec–Mangue languages and correctly established the major subgroupings of the Oaxacan group. And in 1926 Schmidt coined the name Otomi–Mangue for a group consisting of the Oto-Pamean languages and Chiapanec–Mangue. The Oto-Pamean group and the Main Oaxacan group were not joined together into one family until in Sapir's

They call for a redoubling of the effort to document and reconstruct several important branches that have received little attention: principally Mixtecan, Popolocan and Oto-Pamean.

However, in his 1987 revision he linked it with Aztec-Tanoan in a "Central Amerind" branch, apart from Tlapanec which, although it had by then been unequivocally linked to Oto-Manguean, he continued to classify as Hokan. No hypotheses including Oto-Manguean in any higher-level unit have been able to withstand scrutiny.

Currently Otomi varieties are spoken collectively by circa 239,000 speakers — some 5 to 6 percent of whom are monolingual. Because of recent migratory patterns, small populations of Otomi speakers can be found in new locations throughout Mexico and in the United States. The Otomi languages are vigorous in some areas, with children acquiring the language through natural transmission (e.g. in the Mezquital valley of Hidalgo and in the Highlands). However three varieties are now considered moribund: those of Ixtenco (Tlaxcala

The varieties of Mixtec are sometimes grouped by geographic area, using designations such as those of the Mixteca Alta, the Mixteca Baja, and the Mixteca de la Costa. However, the dialects do not actually follow the geographic areas, and the precise historical relationships between the different varieties have not been worked out. The number of varieties of Mixtec depends in part on what the criteria are for grouping them, of course; at one extreme, government agencies once recognized no dialectal diversity.

Syllable structure

Proto-Oto-Manguean allowed only open syllables of the structure CV (or CVʔ). Syllable initial consonant clusters are very limited, usually only sibilant-CV, CyV, CwV, nasal-CV, ChV, or CʔV are allowed. Many modern Oto-Manguean languages keep these restrictions in syllable structure but others, most notably the Oto-Pamean languages, now allow both final clusters and long syllable initial clusters. This example with three initial and three final consonants is from Northern Pame

 adds the proto-phonemes */ts/, */θ/, */x/, *//, */l/, */r/, */m/ and */o/, and the vowel combinations */ia/, */ai/, */ea/, and */au/.

The Oto-Manguean languages have changed quite a lot from the very spartan phoneme inventory of Proto-Oto-Manguean. Many languages have rich inventories of both vowels and consonants. Many have a full series of fricatives, and some branches (particularly Zapotecan and Chinantecan) distinguish voicing in both stops and fricatives. The voiced series of the Oto-Pamean languages have both fricative and stop allophones. Otomian also have full series of front, central and back vowels. Some analyses of Mixtecan include a series of voiced prenasalised stops and affricates; these can also be analysed as consonant sequences but it would be the only consonant clusters known in the languages.

These are some of the most simple sound changes that have served to divide the Oto-Manguean family into subbranches:

Tone systems

The Oto-Manguean languages have a wide range of tonal systems, some with as many as 10 tone contrasts and others with only two. Some languages have a register system only distinguishing tones by the relative pitch. Others have a contour system that also distinguishes tones with gliding pitch. Most however are combinations of the register and contour systems. Tone as a distinguishing feature is entrenched in the structure of the Oto-Manguean languages and in no way a peripheral phenomenon as it is in some languages that are known to have acquired tone recently or which are in a process of losing it. In most Oto-Manguean languages tone serves to distinguish both between the meanings of roots and to indicate different grammatical categories. In Chiquihuitlan Mazatec

 only have the level tones and no combination.
In some languages stress influences tone, for example in Pame only stressed syllables have a tonal contrast. In Chatino where stress falls predictably on the last syllable of polysyllables, tone is also only distinguished on the last syllable. In Mazahua The opposite occurs and all syllables except the final stressed one distinguishes tone. In Tlapanec stress is determined by the tonal contour of the words. Most languages have systems of sandhi
