When I moved to Scotland from America I was not aware of just how many thousands of differences there are in the language. Many books have been written on this subject. When one travels from Britain to the US or vice versa, a British/American English dictionary is required!

I have had to become multilingual! English in the US, in England, and Scotland are NOT the same. Now I'm in Uganda where English is their second language....but that's a whole other subject.

A few of the common differences - US vs UK (in general)
gas - petrol
gas station - garage (gairij)
trash can - bin
garbage - rubbish
eggplant - aubergine
zucchini - courgette
shopping cart - trolley
french fries - chips
potato chips - crisps
cigarette - fag
offer a ride in a car - offer a lift (ride is sexual)
woman's bits - fanny
damn - bloody
movie theater - cinema
guy/dude - bloke
yard - garden
confused/befuddled - lost the plot
flabbergasted - gobsmacked
vacation - holiday

pants - trousers
underwear - pants
outfit (clothing) - kit
call (on phone) - phone
bathroom/restroom - loo, toilet
period (end of sentence) - full stop

crazy - daft as a brush
stupid - thick as mince
supper - tea

US vs Scotland (English slang and Scots language - Lowlands)

In order to be understood I had to begin saying things like twenty instead of twunnie and water instead of wadder. Dates are written differently - 1/10/08 in US = 10/1/08 in UK. Loads of other differences as well.

Google British American English for a wealth of info.
