“Green’s Dictionary of Slang is the largest historical dictionary of English slang. Written by Jonathon Green over 17 years from 1993, it reached the printed page in 2010 in a three-volume set containing nearly 100,000 entries supported by over 400,000 citations from c. AD 1000 to the present day. The main focus of the dictionary is the coverage of over 500 years of slang from c. 1500 onwards. The printed version of the dictionary received the Dartmouth Medal for outstanding works of reference from the American Library Association in 2012; fellow recipients include the Dictionary of American Regional English, the Oxford Dictionary of National Biography, and the New Grove Dictionary of Music and Musicians. It has been hailed by the American New York Times as ‘the pièce de résistance of English slang studies’ and by the British Sunday Times as ‘a stupendous achievement, in range, meticulous scholarship, and not least entertainment value’. On this website the dictionary is now available in updated online form for the first time, complete with advanced search tools enabling search by definition and history, and an expanded bibliography of slang sources from the early modern period to the present day. Since the print edition, nearly 60,000 quotations have been added, supporting 5,000 new senses in 2,500 new entries and sub-entries, of which around half are new slang terms from the last five years.”
