In Wikipedia you can find a list of language academies, which are organizations that weigh in on what is and is not right and proper in a given language.

They exist in Germany, France, the Netherlands, and many other countries—but note the absence of one for English!

Such academies are by definition kind of bossy about how things should be done. It’s hard to imagine such a thing going over well in the U.S., where language problems flourish amid chaos alternately gleeful and strident.
