Languages of Mexico

The Constitution of Mexico does not declare an official language; however, Spanish is the de facto national language spoken by over 90% of the population although English is spoken by 5% also. making it the largest Spanish speaking country in the world. Due to the cultural influence of the United States, American English is widely understood, especially in border states and tourist regions, with a hybridization of Spanglish spoken. The government recognizes 63 indigenous languages spoken in their communities out of respect, including Nahuatl, Mayan, Mixtec, etc.

The Mexican government uses solely Spanish for official and legislative purposes, but it has yet to declare it the national language mostly out of respect to the indigenous communities that still exist. Most indigenous languages are endangered, with some languages expected to become extinct within years or decades, and others simply having populations that grow slower than the national average. According to the Commission for the Development of Indigenous Peoples (CDI) and National Institute of Indigenous Languages (INALI), while 9% of the population identifies as belonging to an indigenous group, around 5–6% speak an indigenous language.

From the arrival of the first Franciscan missionaries, Spanish, Latin, and indigenous languages played parts in the evangelization of Mexico. Many 16th-century churchmen studied indigenous languages in order to instruct native peoples in Christian doctrine. The same men also found Castilian and Latin appropriate in certain contexts. All told, there existed a kind of "linguistic coexistence" from the beginning of the colonial period.

Some monks and priests attempted to describe and classify indigenous languages with Spanish. In 1570, Philip II of Spain made Nahuatl an official language of the colonies of New Spain to facilitate communication between the natives of the colonies.

In 1696, the government of Charles II reversed that policy and banned the use of any languages other than Spanish throughout New Spain. Beginning in the 18th century, decrees ordering the Hispanization of indigenous populations became more numerous and Spanish colonizers no longer learned the indigenous languages.

After independence the government initiated an educational system with the primary aim of Hispanization of the native populations. This policy was based on the idea that this would help the indigenous peoples become a more integrated part of the new Mexican nation.

Except for the Second Mexican Empire, led by the Habsburg Maximilian I, no Mexican government tried to prevent the loss of indigenous languages during the 19th century.

The 1895 census records some 16% of the populace spoke various indigenous languages "habitually," while 0.17% spoke foreign languages. The rest, 83.71%, spoke primarily Spanish.
