Linguistic term for jargon of a group

A cant is the jargon or language of a group, often employed to exclude or mislead people outside the group. It may also be called a cryptolect, argot, pseudo language, anti language or secret language. Each term differs slightly in meaning; their uses are inconsistent. Richard Rorty defines cant by saying that "'Cant', in the sense in which Samuel Johnson exclaims, 'Clear your mind of cant,' means, in other words, something like that which 'people usually say without thinking, the standard thing to say, what one normally says'." In Heideggerian terms it is what "das Man" says.

The thieves' cant was a feature of popular pamphlets and plays, particularly between 1590 and 1615, but continued to feature in literature through the 18th century. There are questions about how genuinely the literature reflected vernacular use in the criminal underworld. A thief in 1839 claimed that the cant he had seen in print was nothing like the cant then used by gypsies, thieves, and beggars. He also said that each of these used distinct vocabularies, which overlapped, the gypsies having a cant word for everything, and the beggars using a lower style than the thieves.

Ulti is a language studied and documented by Bhaktiprasad Mallik in his book Languages of the Underworld of West Bengal. Ulti is an anti language derived from Bengali and used by criminals and affiliates. The Ulti word kodān 'shop' is derived from rearranging the letters in the Bengali word dokān, which also means 'shop'.
