A dialect of English whose pronunciation is frozen along with that of Canadian English. While British English had some drastic sound shifts, American and Canadian English pronunciation had only undergone a few minor vowel changes, as well as the changing of some Ts and Ds to alveolar flaps (butter sounds somewhat like "budder").

Most of the different spellings of American English (which, for all of you elitest Britons out there, are listed in the OED) developed in the U.S.'s early years, some of them created by dictionary maker Noah Webster. The differences are comparable to the ones between Brazilian Portuguese and Portuguese Portuguese.

Another interesting fact about American and Canadian English is that both dialects still use the -ize spelling for words (organize, organization, etc.), while countries outside North America have almost completely dumped it for the newer -ise spelling. However, the OED and Fowler's Modern English Usage (both of which are decent books of British origin) prefer the -ize spelling. Folks from North America also use the older aluminum spelling instead of the newer aluminium spelling. (Though neither spelling is the original; the original is alumium.)

Americans also refer to the letter Z using the 17th century name "zee" instead of the name "zed" used elsewhere (including in Canada). Rest assured, the name "izzard" is pretty much obsolete.

Give American English a break. There's nothing wrong with having a little bit of diversity in the Anglosphere. You don't see us complaining about your dialect every second, do you?

American English is a version of English that actually predates British English; when the colonists were sent over to America, the language essentially "froze" because of broken contact with the British island. The linguistical isolation that ensued caused the English language to split into two main dialects: American and British English.

Contrary to popular belief, American English is not ebonic slang and it is very hard to definitively pin down American and British English, due to the fact that language constantly evolves. Slang does occasionally make its way into the long term lexicon, but only when spoken by a large percentage of the people. Therefore, it is very unlikely that gangsta speech or ebonics will ever be anything more than bastardized slang.
Words like 'fall' and 'autumn' mean the same thing, but one word is actually older than the other, and is in more common usage due to the isolation caused by the

American English is a language that has so many obvious rules that almost only Americans break.
