Slang is used for many purposes, but generally it expresses a certain emotional attitude; the same term may express diametrically opposed attitudes when used by different people. Many slang terms are primarily derogatory, though they may also be ambivalent when used in intimacy or affection. Some crystallize or bolster the self-image or promote identification with a class or in-group. Others flatter objects, institutions, or persons but may be used by different people for the opposite effect. "Jesus freak," originally used as ridicule, was adopted as a title by certain street evangelists. Slang sometimes insults or shocks when used directly; some terms euphemize a sensitive concept, though obvious or excessive euphemism may break the taboo more effectively than a less decorous term. Some slang words are essential because there are no words in the standard language expressing exactly the same meaning; e.g., "freak-out," "barn-storm," "rubberneck," and the noun "creep." At the other extreme, multitudes of words, vague in meaning, are used simply as fads.

There are many other uses to which slang is put, according to the individual and his place in society. Since most slang is used on the spoken level, by persons who probably are unaware that it is slang, the choice of terms naturally follows a multiplicity of unconscious thought patterns. When used by writers, slang is much more consciously and carefully chosen to achieve a specific effect. Writers, however, seldom invent slang.

It has been claimed that slang is created by ingenious individuals to freshen the language, to vitalize it, to make the language more pungent and picturesque, to increase the store of terse and striking words, or to provide a vocabulary for new shades of meaning. Most of the originators and purveyors of slang, however, are probably not conscious of these noble purposes and do not seem overly concerned about what happens to their language.

10. Attitudes toward slang

With the rise of naturalistic writing demanding realism, slang began to creep into English literature even though the schools waged warfare against it, the pulpit thundered against it, and many women who aspired to gentility and refinement banished it from the home. It flourished underground, however, in such male sanctuaries as lodges, poolrooms, barbershops, and saloons.

By 1925 a whole new generation of U.S. and European naturalistic writers was in revolt against the Victorian restraints that had caused even Mark Twain to complain, and today any writer may use slang freely, especially in fiction and drama. It has become an indispensable tool in the hands of master satirists, humorists, and journalists. Slang is now socially acceptable, not just because it is slang but because, when used with skill and discrimination, it adds a new and exciting dimension to language. At the same time, it is being seriously studied by linguists and other social scientists as a revealing index to the culture that produces and uses it.

11. Formation

Slang expressions are created by the same processes that affect ordinary speech. Expressions may take form as metaphors, similes, and other figures of speech (dead as a doornail). Words may acquire new meanings (cool, cat). A narrow meaning may become generalized (fink, originally a strikebreaker, later a betrayer or disappointer) or vice-versa (heap, a run-down car). Words may be clipped, or abbreviated (mike, microphone), and acronyms may gain currency (VIP, awol, snafu). A foreign suffix may be added (the Yiddish and Russian -nik in beatnik) and foreign words adopted (baloney, from Bologna). A change in meaning may make a vulgar word acceptable (jazz) or an acceptable word vulgar (raspberry, a sound imitating flatus; from raspberry tart in the rhyming slang of Australia and Cockney London; Sometimes words are newly coined (oomph, sex appeal, and later, energy or impact).

12. Position in the Language

Slang is one of the vehicles through which languages change and become renewed, and its vigor and color enrich daily speech. Although it has gained respectability in the 20th century, in the past it was often loudly condemned as vulgar. Nevertheless, Shakespeare brought into acceptable usage such slang terms as hubbub, to bump, and to dwindle, and 20th-century writers have used slang brilliantly to convey character and ambience. Slang appears at all times and in all languages. A person’s head was kapala (dish) in Sanskrit, testa (pot) in Latin; testa later became the standard Latin word for head. Among Western
