hello, i am canadian, and we use british english. marie-helene is actually wrong. americans spell it "favor", where us canadians and british spell it "favour"... she was backwards... and american english is not very formal, unlike british english...brits do not use slangs and stuff like that. americans also shorten words when spoken. example "y'all" wich means "you all" where british and canadians say both words.

The differences between American and British English are differences in spellings. For example: aluminum, aluminium. In pronounciation, American english has two special sounds called American "R" and "T", in telling the differences, it is better to hear the differences. I have posted some information on my website at http://arcoplaza.com, you will find it under e-lerning. Click onto the Institute of Artificial Intelligence banner to get access. The voices were generated by machine, the first part delivery in Engligh with American accent, and the second half delivery in English with British accent.

Different spelling, different words (jelly and jam both go on toast in america), different pronunciation, different 'set phrases' (americans "organize a desk" after they have purchased it). The list of differences is very very long, but perhaps irrelevant.

You will be understood by all speakers of english, regardless of whether you use British or American English. Some words are spelled differently, but most are still recognizable, with only one or two different letters, and when you are actually speaking it, it won't matter. Even in Australia, most of us use a mixture of British english and American english, so don't be concerend at all. They are essentially the same.

this quesiton cant be answered with some sentence. the difference is huge, the prunanciation, the phrases, everything.you gotta decide wich one you want to learn
