Synonym discussion
Sense: noun/2
All four terms describe varieties of language used by particular groups, but they differ in secrecy, formality, and social scope. 'Cant' (sense 2) suggests a secret vocabulary deliberately used to exclude outsiders — historically associated with thieves, beggars, and criminal networks. 'Argot' is nearly synonymous but carries a more academic or literary flavour, often used by linguists writing about underworld speech. 'Jargon' refers to the technical vocabulary of a profession or hobby (medical jargon, computer jargon); it is about expertise rather than secrecy. 'Slang' is the broadest and most informal, covering casual, playful, or non-standard words used by any social group — teenagers, musicians, sports fans. 'Dialect' differs fundamentally: it is a regional or social variety of a language that includes grammar and pronunciation, not just specialised vocabulary. In practice, a pickpocket's cant keeps their trade hidden from the police, a doctor's jargon makes communication precise among colleagues, and a teenager's slang signals group identity — three different social functions expressed by these overlapping words.
Etymology
The word 'cant' has two separate origins that merged into modern English. The hypocritical-speech meaning (noun sense 1 and verb sense 1) comes from Latin 'cantare' (to sing), via Old Northern French 'cant' (song). It was first used in English to describe the whining singing of beggars, then shifted to mean the special language beggars used among themselves, and later broadened to mean insincere or formulaic moral talk — as if the speaker were just 'singing a tune' without true feeling. The tilt/slope meanings (noun geometry sense, verb sense 2, adjective sense 1) come from a different source: Latin 'canthus' (iron tire of a wheel) and later 'canton' (corner), which developed into the idea of a slanted edge or angled surface. These two roots are unrelated but happen to share the same spelling in modern English.
