The term "Otomanguean" refers to a family of indigenous languages spoken primarily in southern Mexico. This language family includes several languages, such as Otomí, Mazatec, and Mixtec, which are used by various ethnic groups in the region. The Otomanguean languages are known for their complex tonal systems and rich cultural heritage. Otomanguean languages are recognized for their historical significance and linguistic diversity. They are part of the broader Mesoamerican linguistic area, which has influenced the development of other languages and cultures in Mexico.
