Slang

slang, unconventional words or phrases that express either something new or something old in a new way. It is flippant, irreverent, indecorous; it may be indecent or obscene. Its colourful metaphors are generally directed at respectability, and it is this succinct, sometimes witty, frequently impertinent social criticism that gives slang its characteristic flavour. Slang, then, includes not just words but words used in a special way in a certain social context. The origin of the word slang itself is obscure; it first appeared in print around 1800, applied to the speech of disreputable and criminal classes in London. The term, however, was probably used much earlier.

Other related types of nonstandard word usage include cant and jargon, synonyms for vague and high-sounding or technical and esoteric language not immediately intelligible to the uninitiate. In England, the term cant still indicates the specialized speech of criminals, which, in the United States, is more often called argot. The term dialect refers to language characteristic of a certain geographic area or social class.
