Jargon is the specialized terminology associated with a particular area of activity. Jargon is normally employed in a particular communicative context and may not be well understood outside that context. The context is usually a particular occupation (that is, a certain trade, profession, vernacular, or academic field), but any ingroup can have jargon. The main trait that distinguishes jargon from the rest of a language is special vocabulary—including some words specific to it, and often different senses or meanings of words, that outgroups would tend to take in another sense—therefore misunderstanding that communication attempt. Jargon is sometimes understood as a form of technical slang and then distinguished from the official terminology used in a particular field of activity.

The terms jargon, slang, and argot are not consistently differentiated in the literature; different authors interpret these concepts in varying ways. According to one definition, jargon differs from slang in being secretive in nature; according to another understanding, it is specifically associated with professional and technical circles. Some sources, however, treat these terms as synonymous. In Russian linguistics, jargon is classified as an expressive form of language, while secret languages are referred to as argots. Jargon is 'the technical terminology or characteristic idiom of a special activity or group'. Most jargon is technical terminology (technical terms), involving terms of art or industry terms, with particular meaning within a specific industry. A main driving force in the creation of technical jargon is precision and efficiency of communication, when a discussion must easily range from general themes to specific, finely differentiated details without circumlocution. Jargon enrichess everyday vocabulary with meaningful content and can potentially become a catchword. While jargon allows greater efficiency in communication among those familiar with it, a side-effect is that it raises the threshold of comprehensibility for outsiders. This is usually accepted as an unavoidable trade-off, but it may also be used as a means of social exclusion (reinforcing ingroup-outgroup barriers) or social aspiration (when introduced as a way of showing off). Some academics promote the use of jargon-free language, as an audience may be alienated or confused by the technical terminology, and thus lose track of a speaker or writer's broader and more important arguments. The French word is believed to have been derived from the Latin word gaggire, meaning 'to chatter', which was used to describe speech that the listener did not understand. The word may also come from Old French jargon meaning 'chatter of birds'. Middle English also has the verb jargounen meaning 'to chatter,' or 'twittering,' deriving from Old French. The first use of the word dates back to the usage of the word in The Canterbury Tales written by Geoffrey Chaucer between 1387 and 1400. Chaucer referred to jargon as the utterance of birds or sounds resembling birds. In colonial history, jargon was seen as a device of communication to bridge the gap between two speakers who did not speak the same tongue. Jargon was synonymous with pidgin in naming specific language usages. Jargon then began to have a negative connotation with lacking coherent grammar, or gibberish as it was seen as a 'broken' language of many different languages with no full community to call their own. In the 1980s, linguists began restricting this usage of jargon to keep the word to more commonly define a technical or specialized language use. The term is used, often interchangeably, with the term buzzword when examining organizational culture. In linguistics, it is used to mean 'specialist language,' with the term also seen as closely related to slang, argot and cant. The use of jargon in language can be used in professional and unprofessional settings. Examples: economics, computing, medical, photography, business, military, politicians, sports, geographical, employee, employer, radio, music, movies, plays, children, adults, professors, students etc. Various kinds of language peculiar to ingroups can be named across a semantic field. Slang can be either culture-wide or known only within a certain group or subculture. Argot is slang or jargon purposely used to obscure meaning to outsiders. Conversely, a lingua franca is used for the opposite effect, helping communicators to overcome unintelligibility, as are pidgins and creole languages. For example, the Chinook Jargon was a pidgin. Although technical jargon's primary purpose is to aid technical communication, not to exclude outsiders by serving as an argot, it can have both effects at once and can provide a technical ingroup with shibboleths. For example, medieval guilds could use this as one means of informal protectionism. On the other hand, jargon that once was obscure outside a small ingroup can become generally known over time. For example, the terms bit, byte, and hexadecimal (which are terms from computing jargon) are now recognized by many people outside computer science.
