According to reports I have read this week a form of English is emerging in London. It combines elements from Cockney, Jamaican and other Caribbean Englishes, and from South Asian varieties of English. It is known as Jafaican (pseudo-Jamaican) by some, but researchers from Lancaster University believe that it is not white kids trying to sound like black kids, but rather young people who are exposed to different varieties of English as they grow up and who incorporate different influences into their speech.
Linguists call it Multicultural London English (MLE) and have found that it is used increasingly in southern England and is replacing Cockney and other dialects. Apparently multicultural Englishes with similar characteristics are emerging in other large UK cities.
Some phonetic characteristics of MLE include a shift of some vowels towards the back of the mouth, the pronunciation of /h/, which isn’t pronounced in Cockney, and th fronting (/θ/ becomes /f/).
Inevitably some reports attract negative and ignorant comments like:
“It’s a ridiculous accent, so fake. All the kids are speaking in it now, I think it sounds so stupid, makes them sound thick along with their non-words like peak and peng. It’s only used by kids who are trying to be gangsters.”
and
“Personally I think the folk that talk in that faux caribbean patois sound like they’re thick. And I’m a Geordie!!! :-)”
and even
“This accent also comes with the lack of understanding of the use of the words your, you’re, there, their and they’re.”
A lack of understanding of the difference between written and spoken language there, perhaps :).
Some reports are more sensible and balanced though:
