> I actually have no idea what French Guyana, Haiti, or Belize typically do to differentiate between people of the American continent(s) and US persons.
In French, people from the Americas are américains. This includes, say québecois and Brazilians. When context matters, people from the US are états-uniens.
Probably because the US are much more mentioned than other American countries. But that’s not really the point, though. People from the US are américains, they’re part of the group of people living in America (which, in French and when it is not qualified, refers to all of them, North, Central, and South).
The point is that nobody would object if you refer to someone from anywhere else in the Americas as américain. Like my lab mate from Buenos Aires or friends from Montréal. And we’re definitely not in Haiti.
