Even when we stated on our home page that this site is not about demonyms, because of popular demand, we are forced to clarify on this issue.
A demonym is a name given to natives or residents of a certain or specific place. The term gentilic was used previously but is now uncommon.
A demonym is usually, but not always, derived from the name of a place.
It's wide known that many people use the term American to refer to the people from the United States of America, hence overlapping the demonyms of the inhabitants of the continent of America (remember that America is one whole continent with three sub continents) with the inhabitants of the country.
So many scholars have proposed the use of many terms to solve this misuse: US American and Unitedstatesian and USian among others.
We strongly believe that US American is a fair demonym for the people of the United States of America; fair for them and fair for the continent inhabitants.
Let the world know that USA should not be called America! America is one whole continent.
