Hahahaha, yes and the Swedish speak.... Ah, never mind.
I think we were more on the subject of dialects and origin of certain words. Not languages
Dialects and qolloquial language are the same thing: Informal, cultural, and geographical.
Therefor, the proper wording would have been American English, being that is is the American dialect of English.
However, it would be redundant to label proper spoken English as English English, being that the root language is self evident.
And in order to find the origin of a word we would need to look in to its respective root language, not just assume an entire language to be formatted around an informal, cultural and local version of itself. I can't find an American language dictionary that will teach me the origin of English words...
