Mexican Spanish (Spanish: español mexicano) is a set of varieties of the Spanish language as spoken in Mexico and in some parts of the United States and Canada, where there are communities of Hispanic origin influenced by North American Spanish-speaking media.Spanish was brought to Mexico in the 16th century. As in all other Spanish-speaking countries (including Spain), different varieties of the language and accents exist in Mexico, for both historical and sociological reasons. However, the best-known varieties outside of Mexico are both the educated and the working-class varieties of central Mexico, largely because the capital, Mexico City, hosts most of the mass communication media with international projection. For this reason, most of the film dubbing identified abroad with the label ""Mexican Spanish"" or ""Latin American Spanish"" actually corresponds to the central Mexican variety.Mexico City was built on the site of Tenochtitlan, the capital of the Aztec Empire. Besides the Aztecs, the region was home to many other Nahuatl-speaking cultures as well; consequently many speakers of Nahuatl continued to live there and in the surrounding region, outnumbering the Spanish-speakers, and the Spanish of central Mexico incorporated a significant number of Hispanicized Nahuatl words and cultural markers. At the same time, as a result of Mexico City's central role in the colonial administration of New Spain, the population of the city included a relatively large number of speakers from Spain, and the city and the neighboring State of Mexico tended historically to exercise a standardizing effect over the language of the entire central region of the country.
