A euphemisməm/ is a generally innocuous word or expression used in place of one that may be found offensive or suggest something unpleasant. Some euphemisms are intended to amuse, while others use bland, inoffensive terms for things the user wishes to downplay. Euphemisms are used to refer to taboo topics (such as disability, sex, excretion, or death) in a polite way, or to mask profanity.
The word comes from Greekεὐφημία (euphemia) "the use of words of good omen", which is a compound of eû (εὖ) "good, well" and phḗmē (φήμη) "prophetic speech; rumour, talk". The eupheme is the opposite of the blaspheme "evil-speaking". The term euphemism itself was used as a euphemism by the ancient Greeks, meaning "to keep a holy silence" (speaking well by not speaking at all).
