Do we really restrict "American" to 'usonano'?
Ĉu ni vere katenas "American" al la vorto 'usonano'?
This is speaking of the kind of American that comes from the United States, an American from anywhere in South or North America would be "amerikano".
Yes, but they system should also accept the word 'amerikano', as I (and many others too who refuse to restrict 'American' to the people of United States), have answered :)
It most certainly should, especially since Esperanto get's rid of the whole American from USA vs American from America problem.
