Thieves' cant

Cant used by various peoples in English speaking countries

Thieves' cant (also known as thieves' argot, rogues' cant, or peddler's French) is a cant, cryptolect, or argot which was formerly used by thieves, beggars, and hustlers of various kinds in Great Britain and to a lesser extent in other English speaking countries. It is now mostly obsolete and used in literature and fantasy role playing, although individual terms continue to be used in the criminal subcultures of Britain and the United States.

Cant is a common feature of rogue literature of the Elizabethan era in England, in both pamphlets and theatre. It was claimed by Samuel Rid to have been devised around 1530 by two vagabond leaders Giles Hather, of the "Egyptians", and Cock Lorell, of the "Quartern of Knaves" at The Devil's Arse, a cave in Derbyshire, "to the end that their cozenings, knaveries and villainies might not so easily be perceived and known". Thomas Harman, a justice of the peace, included examples in his account A Caveat or Warning for Common Cursitors, first published in 1566. He collected his information from vagabonds he interrogated at his home in Essex. He also called it "pedlars' French" or "pelting speech", and was told that it had been invented as a secret language some 30 years earlier. The earliest records of canting words are included in The Highway to the Spitalfields by Robert Copland c. 1536. Copland and Harman were used as sources by later writers. A spate of rogue literature started in 1591 with Robert Greene's series of five pamphlets on cozenage and coney catching. These were continued by other writers, including Thomas Middleton, in The Black Book and Thomas Dekker, in The Bellman of London (1608), Lantern and Candlelight (1608), and O per se O (1612). Cant was included together with descriptions of the social structure of beggars, the techniques of thieves including coney catching, gull groping, and gaming tricks, and the descriptions of low lifes of the kind which have always been popular in literature. Harman included a canting dictionary which was copied by Thomas Dekker and other writers. That such words were known to a wide audience is evidenced by the use of cant words in Jacobean theatre. Middleton and Dekker included it in The Roaring Girl, or Moll Cut Purse (1611). It was used extensively in The Beggars' Bush, a play by Francis Beaumont, John Fletcher and Philip Massinger, first performed in 1622, but possibly written c. 1614. The play remained popular for two centuries, and the canting section was extracted as The Beggars Commonwealth by Francis Kirkman as one of the drolls he published for performance at markets, fairs and camps. The influence of this work can be seen from the independent life taken on by the "Beggar King Clause", who appears as a real character in later literature. The ceremony for anointing the new king was taken from Thomas Harman and described as being used by Romani people in the nineteenth century. Bampfylde Moore Carew, who published his picaresque Life in 1745, claimed to have been chosen to succeed "Clause Patch" as King of the Beggars, and many editions of his work included a canting dictionary. Such dictionaries, often based on Harman's, remained popular, including The Canting Academy, or Devils Cabinet opened, by Richard Head (1673), and BE's Dictionary of the Canting Crew (1699).
