The Survey of English Dialects took a recording from a long-time resident of Hackney, and the BBC made another recording in 1999 which showed how the accent had changed.John Camden Hotten, in his Slang Dictionary of 1859, makes reference to "their use of a peculiar slang language" when describing the costermongers of London's East End.Als u in Nederland woont kunt u het beste lid worden van een van de vele plaatselijke afdelingen van de NBv V.U ontvangt dan maandelijks het tijdschrift 'Onze Vogels', u krijgt uw eigen kweeknummer en u kunt ringen voor uw vogels bestellen.A common view is that in order to be a cockney, one must have been born within earshot of Bow Bells, the bells of St Mary-le-Bow.However, the church of St Mary-le-Bow was destroyed in 1666 by the Great Fire of London and rebuilt by Sir Christopher Wren.The use of such a literal definition produces other problems, since the area around the church is no longer residential and the noise of the area makes it unlikely that many people would now be born within earshot of the bells, although the Royal London Hospital, Guy's Hospit, Lying In Hospitall and St Thomas' Hospital are within the defined area covered by the sound of the Bow Bells.
The traditional core districts of the East End are Bethnal Green, Whitechapel, Spitalfields, Stepney, Wapping, Limehouse, Poplar, Clerkenwell, Aldgate, Shoreditch, Millwall, Cubitt Town, Hackney, Hoxton, Bow and Mile End.
In London's East End, some traditional features of cockney have been displaced by a Jamaican Creole-influenced variety popular among young Londoners (sometimes referred to as "Jafaican"), particularly, though far from exclusively, those of Afro-Caribbean descent.
Nevertheless, the glottal stop, double negatives, and the vocalisation of the dark L (and other features of cockney speech), along with some rhyming slang terms are still in common usage.
Today cockney-speaking areas include parts of Dagenham, Barking, Billericay, Brentwood, Romford, Chigwell, Loughton, Harlow, Basildon, Thurrock.
Cockney speakers have a distinctive accent and dialect, and occasionally use rhyming slang.
