Or American English and maybe southern American English? Not sure thats different enough to count.
Depending on how diverged they are people can communicate between them with various words or phrases that are different.
Ex. Americans use the word toilet, England uses loo (which might also refer to the whole bathroom? I’m sure someone from England will correct me)
Here in the upper mid west a lot of schools teach Spanish. Not at a you can speak level usually. Similar to how a lot of people learn biology and forget it all when they graduate.
In my state there was some reason they wanted us all to take a second language (I think it was some scholarship we would qualify for our something?) and I always thought the reason most schools had Spanish was because finding a teacher certificated to teach Spanish was more common than other languages. And both of mine were just Midwest white dudes.
