If Americans want to say Twat they should say it properly.

There is a very irritating trend in US TV where an actor will use "twat" as an insult, but pronounce it "twot" ... it is painful and I need it to stop.

"Oregon is pronounced O-reh-gon, O as in Octopus emphasis on the reh."

Huh? Emphasis on the 'reh'? I'm sure I've never heard it said like that.
I've only heard it with the emphasis on the first syllable: - O-reh-gon.

Oregon (not even close to the US pronunciation of oregano)

To the Americans: 'coopay' or 'coop' for coupé (admittedly it's more usually spelled coupe)?

Like the car? Coop. Military is coo.

Gallagher to me is gal-uh-gurr. Not really stressed anywhere...maybe a bit on the first syllable.

I'll let you work out he pronunciation of the name of the lake there

Y'all would love the way local people in a town near me pronounce the name of the town's main street, which is Gloucester.

I can hazard a guess.

We used to be mean and take Californian cousins to Lympne in Kent

Get over yourselves. We live in a multicultural society, like it or please leave.

In a country who can't decide whether it is scone or scone, you are in no position to lecture anyone on how they should pronounce things if they are not even from here.

I did have an interesting conversation with a man from Philadelphia (if that's significant) who kept "correcting" my pronunciation of Edinburgh. As in, I'd say "I was in Edinburgh when..." and he'd reply, "So when were you in Edin boorg?" etc.

"Americans" can say whatever the fuck they like, basically. Screw you! (said in New York accent, the "only" way it should e said)

I say! (said in a Home Counties accent - not mine)

That's close. It's sort of Glou (rhymes with cow) ces ter, with emphasis on the ces. But there are a lot of incomers from Northern and foreign parts who are causing the pronunciation to change slowly. The whole town and most of its streets are named after various Hanoverian royal folk. The founder was obviously trying to toady up to George II (after whom the state is named, btw).

Swedish There is an Edinburg (note spelling) in Pennsylvania, pronounced with the final g.

Oregonians pronounce Oregon with two syllables: or-gun.

Yy CJ Craig, not Creg, I would yell, whilst watching the west wing.

Twot is so wrong, like loyd Grossman saying Twat.

Interesting Seneca. But this man had visited the Scottish one a lot. It was like a battle to see if we could keep getting the word into each sentence without acknowledging what we were doing.

I was reading this thread earlier and my dh, who is deepest Suffolk born and bred, called a chap on the tv a twot......

This from people who cannot pronounce Arkansas...

But CJ's name is Cregg, not Craig.

Well, Swedish, he has no excuse then. Interesting tidbit: The last syllable of Pittsburgh was originally supposed to be pronounced as in Edinburgh, put somehow became "burg" along the way.

This from people who cannot pronounce Arkansas...

Kansas and Arkansas are related words based on American Indian tribes, but for historical reasons, Arkansas was given a French pronunciation so the last s is silent. In the south central US accent, the "sa" sound became "saw."

No, there are two ways to pronounce laugh - lahf vs laff - and two ways to pronounce scarf - scahf vs scarr-f. So yes the rhotic r comes into it, in scarf. It doesn't (or shouldn't) come into laugh because there is no r in laugh.

It makes me laugh when some British people try to do an American accent and just put the r sound on the end of all long a (ah) sounds regardless of whether they are spelled ar or au or ah or a.

I was repeatedly questioned by an American waiter when I wanted water once... I ended up miming and he said "Oh you mean WADER".

It's probably not a "d", more likely a flap.

I know what you mean OP - in our house we joke about watching the "Wocking Dead" and only recently figured out that Rick Grimes' son is called Carl, not "Coral".

Agreed, Bertie. The most common problem that British actors have in doing American accents is overdoing the "r" even when there is an "r" there. But having said that, I think in general, British actors are better at American accents than American actors are at British accents. The current prize goes to Alan Cumming in the Good Wife. I think Scots may have a head start because most of them have the rhotic r.
