What governing body tried Esperanto? None that I know of.
Accurate description, that’s exactly how it is. Also, bear in mind that the country gets its fair share of American tourists. Yet, it’s the Queen’s English in school.
From what I understand, e.g. Mexicans think of “European” Spanish that it is a tad stiff, a bit archaic - Mexican has a lot of slang woven into it. Probably very similar to how Americans regard the Queen’s English. So, in Mexican schools, do the kids get “Mexican” Spanish? Good question.
