Well, everybody born in the american continent is technically “american” too, including Central and South America. Is there a specific term in english for these people?
Edit: Thanks for all your answers, especially the wholesome ones and those patient enough to explain it thoroughly. Since we (South Americans) and you (North Americans) use different models/conventions of continent boundaries, it makes sense for you to go by “Americans”, while it doesn’t for us.
Words can be coined. America is a continent. There, if the word didn’t exist before, it does now.
You’re right that words can be coined and their usage changed, but you seem to be misinformed about how that happens. You just deciding we’re gonna do it this way now in a random thread on lemmy is not gonna cut it, sorry
