America is a vast country that stretches over 3,500 miles of land and further thousands across the Pacific to the faraway state of Hawaii. With 50 states populated by people from all over the world who picked up the English language from a vast variety of sources, Americans handle the English language in an enormously varied way.
Even within individual cities, things change as you go from neighborhood to neighborhood, and even within a matter of a few blocks. American English is influenced by Spanish, German, Native American, Creole, French and other cultures that merged together to synthesize something that is itself gloriously diverse, very new, and uniquely belonging to America instead of to all of its parent countries. All together, this has created some of the most recognizable accents in the world.
While American English is not nearly as defined by class as its many British counterparts, it is heavily affected by geography and, to a lesser extent, by education. What's especially curious about American English is that it actually has a couple of versions - General American and Mid-Atlantic - that are considered by most Americans to be something approaching "neutral" American accents, a category that certainly does not exist in Britain.
