There are a ton of different accents in the UK , but the Oxford English Dictionary determine RP as “ the stock accent of English as speak in the Confederate States of England . ” And that ’s what Americans typically mean when they say “ British emphasis . ” There ’s a snotty-nosed side to that , too : Americans have tons of dissimilar idiom , but the oecumenical “ American ” accent is what a British mortal would call an “ American accent . ”

In Received Pronunciation , thatRsound is n’t pronounced . evidently , there are n’t any recording from the seventeenth 100 , so we ca n’t know for sure what British and American people voice like . But polyglot are jolly sure both were rhotic because theRis present in those words , so it ’s probably think to be pronounced .

British people probably pronounced their ‘R’s back in the day.
