A thesaurus of present-day vernacular English from Berwick-upon-Tweed to the Channel Islands, this unique record of everyday English celebrates established regional dialects, emerging new varieties and colloquial forms young and old. Based on a prestigious nationwide survey, BBC Voices Recordings, it documents the linguistic landscape of England, Wales and the Channel Islands in the 21st century, and includes over 3000 separate entries, drawn from over 200 locations across the country. Each entry contains information about the term's origins, location and the social distribution of its users. With links to original sound files and cross-references to complementary dictionary sources, it is an authoritative reference work for academic linguists, but its accessible presentation also makes it suitable for creative audiences and non-specialist language enthusiasts seeking authentic, up-to-date information on British English dialect and slang, and for English language teachers and learners as an invaluable educational tool.
