At my Mexican Language page (, we look at how Mexican Spanish is influenced by Aztec, Mayan languages and others.

Did you know that Spanish is not even the official language of Mexico?

Here is an excerpt from the Wikipedia article:

Spanish is the de facto national language of spoken by the vast majority of Mexicans, though it is not defined as an official language in legislation. The second article of the 1917 Constitution defines the country as multicultural, recognizes the right of the indigenous peoples to "preserve and enrich their languages" and promotes "bilingual and intercultural education".

There is language learning software to help you learn Mexican Spanish, which is also the widest spoken variety of Spanish in the US, for example. Check out my site for more.
