London
There are many accents traditionally associated with London. The most well known of the London accents long ago acquired the Cockney label from London's East End, which is heard both in London itself, and across the wider South East England region more generally. The accent of a 21st-century Londoner varies widely; what is becoming more and more common amongst the under-30s however is some fusion of Cockney with a whole array of ethnic accents, in particular Caribbean, which form an accent labelled Multicultural London English (MLE). The other widely heard and spoken accent is RP (Received Pronunciation) in various forms, which can often be heard in the media and many of other traditional professions and beyond, although this accent is not limited to London and South East England, and can also be heard selectively throughout the whole UK amongst certain social groupings. Since the turn of the century the Cockney dialect is less common in the East End and has 'migrated' east to Havering and the county of Essex.
English-language vowel changes before historic /r/
Words that would have a stressed before intervocalic in the UK's Received Pronunciation (RP) are treated differently in different varieties of North American English. As shown in the table below, in Canadian English, all of these are pronounced with , as in "cord" (and thus merge with historic prevocalic in words like "glory" because of the horse–hoarse merger). In the accents of Philadelphia, southern New Jersey, and the Carolinas (and traditionally throughout the South), these words are pronounced among some with , as in "card" (and thus merge with historic prevocalic in words like "starry"). In the accents of New York City, Long Island, and nearby parts of New Jersey, these words are pronounced with like in RP. However, this is met with hypercorrection of , (thus still merging with historic prevocalic in "starry"). On the other hand, the traditional Eastern New England accents (famously, the Rhode Island and Boston accents) these words are pronounced with without hypercorrection, just like in RP. Most of the rest of the United States (marked "General American" in the table), however, has a distinctive mixed system: while the majority of words are pronounced as in Canada, the four (sometimes five) words in the left-hand column are typically pronounced with ; and the East Coast regions seem to be slowly moving toward this system over time.
