Spanish is the official and national language of Mexico. Nearly 90% of the population speaks Spanish. It was introduced within Mexico during the Spanish dominion. The Mexican Spanish and traditional Spanish have same roots and do not have any significant differences. Although the Mexican-Spanish does have certain words that are pronounced differently. This pronunciation gap is found due to the colorization of Indian language with the traditional Spanish. Most of the pronunciation differences are found in the household and food items.
The Mexican population is largely bilingual and about 5.5 million people also speak at least one indigenous language.
