Fuck () is a profanity in the English language that often refers to the act of sexual intercourse, but is most commonly used as an intensifier or to convey disdain. While its origin is obscure, it is usually considered to be first attested to around 1475. In modern usage, the term fuck and its derivatives (such as fucker and fucking) are used as a noun, a verb, an adjective, an infix, an interjection, or an adverb. There are many common phrases that employ the word as well as compounds that incorporate it, such as motherfucker and fuck off.

==Offensiveness== It is unclear whether the word has always been considered a pejorative or, if not, when it first came to be used to describe (often in an extremely angry, hostile, or belligerent manner) unpleasant circumstances or people in an intentionally offensive way, such as in the term motherfucker, one of its more common usages in some parts of the English-speaking world. Some English-speaking countries censor it on television and radio. Andrea Millwood Hargrave's 2000 study of the attitudes of the British public found that fuck was considered the third-most-severe profanity, and its derivative motherfucker second. Cunt was considered the most severe.
