A New Dictionary of the Terms Ancient and Modern of the Canting Crew is a dictionary of English cant and slang by a compiler known only by the initials B. E., first published in London c. 1698. With over 4,000 entries, it was the most extensive dictionary of non-standard English in its time, until it was superseded in 1785 by Francis Grose's Classical Dictionary of the Vulgar Tongue. B. E.'s New Dictionary was used as a source by many subsequent dictionaries.
