Differences between American & British English

Both have so much in common, but so much different as well.
Vocabulary such as lorry vs. truck; or flat vs. apartment.

they are actually pretty similar

i have never had a problem understanding americans on television

no website has ever struck me as being peculiarly american either

the differences are overplayed for effect

I have had problems with american understanding me.
Once I said "brill!" instead of the American "cool", they said "what?"

perhaps they are not as exposed to our dialect as we our to theirs

with exposure they would soon have no problem with it though

to be fair some britons would not know what brill meant

some would consider it a fish

Well, yes you're right. There are quite a lot more American films on screen than British, the same for TV serieses, etc.

N Americans seem to speak and ignore the syllables quite often. I,e
intead of "in-te-res-ting they say int-e-resting. This is done quite to
many words. My nam eis always pronounced "mart-un" and not Mar-tin".

many british people also do the same

'intresting' is often heard for 'interesting'

'probly' for 'probably'

even 'praps' for 'perhaps'

Furthermore, the American accent is so boring, with no entonation. The word stress is barely detected in American accent, whereas us, the Brits, entonate more, or put some feeling in the speaking, not just blablabla.

David,

We do hear entonation. Can you hear the difference between different American accents?

Well, yes, I agree there are plenty of American accents, but anyway all of them are very similar, don't differ so much.
The American entonation and word stress is boring ( I'm not saying there's no entonation at all), just that it is less entonated.
Furthermore, the Americans pronounce water as "waerur" instead of "wa-taer" and the 't' in isn't it, doesn't it dissapears. The 't' in refrigerator is pronounced like an "r" like "refrigeraror" and very fastly not clearly enough.

Well, I find British accents boring! Nah-nah-nah-nah-nah-nah!!!

Please, English accents are just different. American-English is simply another groups of English accents; just as Canadian and Australian and South African English are different from British English accents.

Guess you're right

As an American, I never pronounce water "waerur", nor do I pronounce refrigerator "refrigeraror".

I'm from the midwest, and I pronounce it phonetically "wauter" and "refridgerator", however I can't speak for the other dialects around the USA.

I also guess it's a matter of taste and what you prefer.

Yeah I never pronounce it that way either. I'm from New Jersey and I'd say I pronounce it something like...waw-ter...although some British people may find my "t" somewhat like a "d." We can distinguish between them though.

As a student, I like American English because there are some reasons.
1) Americans pronounce words loudly and clearly.

2) Their accents vary from people to people and that's cool stuff. Never boring. Once you get used to listening their accents, you'll enjoy listening to them.

3) No hard and fast grammar rules. For example, They use "will" with all subjects in expressing views in the simple future tense.

4) Their spelling of words are quite simple and easy to remember.
For example: Center, (instead of 'centre'), Colour, (instead of 'color').

5) Lingo, Learning American slang terms is awesome. I'm not sure whether British speakers have a lingo or not. I normally hear American lingo on TV.
For example, bullshit, chow, cool, hood, dipshit, jackass, freak out, pinhead, homey, pad, copycats...etc
