A euphemism is a substitution of an agreeable or less offensive expression in place of one that may offend or suggest something unpleasant to the listener, or in the case of doublespeak, to make it less troublesome for the speaker.Fact: date=April 2008 It also may be a substitution of a description of something or someone rather than the name, to avoid revealing secret, holy, or sacred names to the uninitiated, or to obscure the identity of the subject of a conversation from potential eavesdroppers. Some euphemisms are intended to be funny.

Usage

When a phrase is used as a euphemism, it often becomes a metaphor whose literal meaning is dropped. Euphemisms may be used to hide unpleasant or disturbing ideas, even when the literal term for them is not necessarily offensive. This type of euphemism is used in public relations and politics, where it is sometimes called doublespeak. Sometimes, using euphemisms is equated to politeness. There are also superstitious euphemisms, based (consciously or subconsciously) on the idea that words have the power to bring bad fortune (for example, not speaking the word "cancer"; see etymology and common examples]] below) and religious euphemisms, based on the idea that some words are sacred, or that some words are spiritually imperiling ([[taboo; see etymology and religious euphemisms below).

Etymology

The word euphemism comes from the Greek word euphemo, meaning "auspicious/good/fortunate speech/kind" which in turn is derived from the Greek root-words eu (ευ), "good/well" + pheme (φήμη) "speech/speaking". The eupheme was originally a word or phrase used in place of a religious word or phrase that should not be spoken aloud; etymologically, the eupheme is the opposite of the blaspheme (evil-speaking). The primary example of taboo words requiring the use of a euphemism are the unspeakable names for a deity, such as Persephone, Hecate, or Nemesis.

Historical linguistics has revealed traces of taboo deformations in many languages. Several are known to have occurred in Indo-European languages, including the original Proto-Indo-European words for bear (*rtkos), wolf (*wlk^wos), and deer (originally, hart; the deformation likely occurred to avoid confusion with heart). In different Indo-European languages, each of these words has a difficult etymology because of taboo deformations—a euphemism was substituted for the original, which no longer occurs in the language. An example is the Slavic root for bear—*medu-ed-, which means "honey eater". One example in English is "donkey" replacing the old Indo-European-derived word "ass". The word "dandelion" (lit., tooth of lion, referring to the shape of the leaves) is another example, being a substitute for pissenlit, meaning "wet the bed", a possible reference to the fact that dandelion was used as a diuretic.
