Slang, contrary to jargon, needs no translation. It is not a secret code. It is easily understood by the English-speaking community and is only regarded as something not quite regular. It must also be remembered that both jargon and slang differ from ordinary language mainly in their vocabularies. The structure of the sentences and the morphology of the language remain practically unchanged. But such is the power of words, which are the basic and most conspicuous element in the language, that we begin unwittingly to speak of a separate language. Many words formerly labeled as slang have now become legitimate units of standard English. Thus the word kid (child), which was considered low slang in the nineteenth century, is now a legitimate colloquial unit of the English literary language. It never grows stale. If a slang word or phrase does become stale, it is replaced by a new slangism. It is claimed that this satisfies the natural desire for fresh, newly created words and expressions, which give to an utterance emotional colouring and a subjective evaluation. The term 'slang', which is widely used in English linguistic science, should be clearly specified if it is to be used as a term, i. e. it should refer to some definite notion and should be definable in explicit, simple terms. It is suggested here that the term 'slang' should be used for those forms of the English vocabulary which are either mispronounced or distorted in some way phonetically, morphologically or lexically. The term 'slang' should also be used to specify some elements which may be called over-colloquial. As for the other groups of words hitherto classified as slang, they should be specified according to the universally accepted classification of the vocabulary of a language. Slang is nothing but a deviation from the established norm at the level of the vocabulary of the language." Sometimes slang is used to escape the dull familiarity of standard words, to suggest an escape from the established routine of everyday life. When slang is used, our life seems a little fresher and a little more personal. Also, as at all levels of speech, slang is sometimes used for the pure joy of making sounds, or even for a need to attract attention by making noise. Examples of words that are considered slang: to take stock in'to be interested in, attach importance, give credence to' bread-basket'the stomach' (a jocular use) to do a flit'to quit one's flat or lodgings at night without paying.
