What do you call someone from the Americas if not American? [closed]
Many outside of the U.S. living in the Americas will argue otherwise. I'd provide clarity by specifying "South American" or "people from the Americas".
In American Spanish, "norteamericano" can be specific to the USA.
There's no clear rule in this case that I am aware of, just make your usage specific enough for the given context to indicate your meaning.
If you're writing a technical document or something for the general public where you cant assume anything about the readers background, be as specific as possible.
