Minced oath

A minced oath is a euphemistic expression formed by misspelling, mispronouncing, or replacing a part of a profane, blasphemous, or taboo term to reduce the original term's objectionable characteristics. Some examples include "gosh" (for God), "darn" and "dang" (for damn), "heck" (for hell), "sugar" or "shoot" (for shit), "fudge" or "frick" or "fvck" (for fuck).

Many languages have such expressions. In the English language, nearly all profanities have minced variants.

Common methods of forming a minced oath are rhyme and alliteration. Thus the word (which itself may be an elision of "By Our Lady"—referring to the Virgin Mary) can become , or . Alliterative minced oaths such as darn for damn allow a speaker to begin to say the prohibited word and then change to a more acceptable expression. In rhyming slang, rhyming euphemisms are often truncated so that the rhyme is eliminated; prick became Hampton Wick and then simply Hampton. Another well-known example is "cunt" rhyming with "Berkeley Hunt", which was subsequently abbreviated to "berk". Alliteration can be combined with metrical equivalence, as in the pseudo-blasphemous "Judas Priest", substituted for the blasphemous use of "Jesus Christ".

Minced oaths can also be formed by shortening: e.g., b for bloody or f for fuck. Sometimes words borrowed from other languages become minced oaths; for example, comes from the Dutch pappe kak, meaning "soft dung". The minced oath blank is an ironic reference to the dashes that are sometimes used to replace profanities in print. It goes back at least to 1854, when Cuthbert Bede wrote "I wouldn't give a blank for such a blank blank. I'm blank, if he doesn't look as if he'd swallowed a blank codfish." By the 1880s, it had given rise to the derived forms blanked and blankety, which combined together gave the name of the long running and popular British TV show Blankety Blank. In the same way, bleep arose from the use of a tone to mask profanities on radio.
