The term jargon can be used for:
- a specialised vocabulary of a profession, or similar group, see: technical terminology.
- a dialect, a heavy distortion of common language, deviant from the official language of a state.
- a idiomatic language used by a small group of people or even a single person, often with a touch of humour or irony. This idiomatic language may appear vague and alienated to outsiders. It may be used disparagingly toward others. (See for example lamer.)
- statements about something made in a routine manner, without deeper analysis of the subject.
