The roots of London's modern street slang are hard to pinpoint, as the city is a linguistic melting pot of the many races that have left their mark on the capital's language. Traditional ""Bow Bells"" Cockney English, West Indian patois, Indian and Bangladeshi have all gone to produce Multicultural London English, the academic term for the modern street slang which is spoken from Harlesden to Hackney and from Streatham to Stoke Newington. I Have worked in the housing sector as a specialist in relation to the housing of ex offenders, vulnerable young people and their families for 10 years. During that time I have also been very involved in the professional development of professionals in related sectors through the training I provide, and the books I write. I have made a point of remaining rooted in the communities I serve that raised me, which I believe has greatly contributed to the efficacy of my work.
