This is something that's been different about the United States for a long time. We have no declared official language. France's official language is French, Mexico's is Spanish...in fact, most of the rest of the world has a declared official language. 32 states in the US have one, and a Michigan politician wants the Mitten to join them.
The other day, I posted a little video featuring some of my friends I worked with at KLAQ in El Paso, as they attempted to pronounce some Michigan and Midwest words.
They failed in spectacular fashion.
So, as punishment, they sent us some Spanish words to try.
You wouldn't think the English language could change so much throughout a single country, but there's a really big difference in words' pronunciations north, south, east and west.
Moving up here from Texas last year, I've begun learning a lot about how things are said here. And I have to be honest: I'm still not any good at the words.
I will still say 'Mack-in-nack' Island, but mostly for funnies
