- a specialized dictionary covering the words, phrases, and idioms that reflect the least formal speech of a language. These terms are often metaphorical and playful, and are likely to be evanescent as the spoken language changes from one generation to another. Much slang belongs to specific groups, as the jargon of a particular class, profession, or age group. Some is vulgar. Some slang terms have staying power as slang, but others make a transition into common informal speech, and then into the standard language. An online slang dictionary, such as the Dictionary.com Slang Dictionary, provides immediate information about the meaning and history of a queried term and its appropriateness or lack of appropriateness in a range of social and professional circumstances.
