Can foreign speakers stop telling us to call ourselves United Statesers instead of Americans?
You outright don't understand the language if you think United Stateser is a viable option.
You see, in a language like spanish you can say estadounidense perfectly fine because of one importnat factor:
The adjective comes after the noun
This is a simple fact of linguistic grammar that causes the issue
Because in english the adjective comes before the noun, a single noun that uses multiple words like in the case of the United States cannot have a denonym ending
this is because if you say United Stateser, you are not saying "United States" with an -er tacked on, you are saying Stateser that is United.
Since the noun that is becoming a denonym is perfectly viable to have that ending, it becomes a separate entity from the adjective that originally made up the noun it previously described
If our language worked like it does spanish (i know not only spanish, im just using it because its a case im fond of), and the US was instead "The States United", you could make a denonym out of it perfectly fine
States Unitian, even though it sounds odd on first hearing, works linguistically
because the denonym ending is on an adjective, something that usually doesn't work with a denonym on its own, causing the word before it to be taken into account as an entire compound noun
now that you have bared through this lesson on the absolute ass that is english, will you please stop complaining about us calling ourselves Americans? Thanks
