Multicultural London English (abbreviated MLE), colloquially called Jafaican, is a dialect (and/or sociolect) of English that emerged in the late 20th century. It is spoken mainly in inner London, with the exception of areas such as Brent, Newham, Haringey and Enfield. According to research conducted at Queen Mary, University of London, Multicultural London English is gaining territory from Cockney.
It is said to contain many elements from the languages of the Caribbean (Jamaica and Trinidad & Tobago), South Asia (Indian subcontinent), and West Africa, as well as remnants of traditional Cockney. Although the street name, "Jafaican", implies that it is "fake" Jamaican, researchers indicate that it is not the language of white kids trying to "play cool" but rather that "[it is] more likely that young people have been growing up in London exposed to a mixture of second-language English and local London English and that this new variety has emerged from that mix".
MLE is used mainly by young, urban working-class people.
