Cant (language)

language culture Maturity 5-7 Next article →

A cant is a specialized jargon or language used by a specific group of people. Often, these groups use this way of speaking to exclude outsiders or to mislead them. This type of communication can also be called a cryptolect, an argot, or an anti-language. While these terms have slightly different meanings, they all describe ways to create private communication. Using a cant allows a group to maintain its own identity. It creates a boundary between those who belong and those who do not.

There are several ways these secret languages function mechanically. One common method is called relexicalisation. In this process, a group keeps the basic grammar of a public language but replaces the vocabulary with new words. Another method is metathesis, which involves reversing the sounds or letters in a word. For example, a speaker might turn "apple" into "elppa." Some groups use coded argots, which are lexically divergent forms of a language. These systems keep the original syntax, or sentence structure, but transform individual words.

Linguists distinguish between different types of these specialized languages. An argot is often seen as a language with its own grammatical system. However, true secret languages are rare because speakers usually share a public language. Many argots are simply specialized vocabularies used in specific fields, such as medicine. Doctors use an argot consisting of technical abbreviations and professional slang. While this can be difficult for patients to understand, it is not always designed to hide meaning. In contrast, an anti-language is used by an anti-society.

An anti-society is a small community created within a larger society to act as an alternative or a form of resistance. The linguist Michael Halliday studied these groups to understand how they maintain their social structures. Anti-languages are used by ostracized groups, such as prisoners, criminals, or teenagers. These groups use the same basic vocabulary and grammar as their native language but in an unorthodox fashion. This creates a "second life" phenomenon where conversation becomes the primary tool for maintaining a separate reality. The study of these languages combines the fields of sociology and linguistics.

History provides two main theories regarding the origin of the word "cant." One school of thought in linguistics suggests it comes from Irish or Scottish Gaelic words for "speech" or "talk." This theory links the word to itinerant groups in Ireland and Scotland who developed creole languages. For instance, the Irish Traveller community uses a variant called Shelta, also known as Gammon. A second theory traces the word to the Latin "cantare," which means "to sing." This path suggests the term originally referred to the chanting of friars between the 12th and 15th centuries.

Over time, the meaning of the word shifted from religious chanting to the singsong speech of beggars and criminals. Many notable examples of these languages exist globally. In London, people use Cockney rhyming slang, while in France, many use Verlan. In Scotland, there are two distinct cants: Scottish Cant for Lowland Romani groups and Beurla Reagaird for Highland Travellers. These two versions are mutually unintelligible, meaning speakers of one cannot understand the other. Other examples include Polari, used by actors and the gay subculture, and Leet, used in internet culture.

Authors also use these concepts to build worlds in fiction. In the novel "A Clockwork Orange," the character speaks a fictional anti-language called Nadsat. Although Nadsat is not a real language that can be studied through live observation, it serves a clear ideological purpose. It helps maintain the social structure of the characters' group, known as the droogs. This shows how language can be used to define social classes and subcultures. Whether real or fictional, these languages demonstrate how humans use speech to navigate complex social systems.
