America is the slang term for the US. As I've said somewhere else in these comments a place is called what the people call it. What everyone else calls it matters not. Germany is a good example. A lot of native tribes are also good examples.
And Americans have difficulty saying the word "Merrka".
Though, come to think of it. Americans mostly generally have difficulty pronouncing the words of the English language anyway ...
It's always, "merica", "murica", The good old US of A". ETC.
