If you mean Spanish, then do you need traditional Cotillion Spanish? or Whats spoken in the U.S (according to region) by people along the border or immigrants.
There are many dialects. For some what is considered a name/word in one region can be a curse word in another especially along the border where words are not used fluently or properly.
For kids? adults? telling someone off? asking directions? etc...
If for kids there is a great Spanish book "mi primer libro de palabras en espanol" isbn # 1-56458-262-0
also great for adults. has pics with words on just about everything in the house, life, animals.
If you mean Mexican words then it would be Mexican Native (tribal Indian); need tribe name and people from it to help you. Mexico didn't have one language but many before Spain invaded and conquered it, thus infusing Spanish into the country.
