None of these acronyms was ever recorded before the 1960s, according to the authoritative lexicographical work The F-Word, and thus are backronyms.
In any event, the word fuck has been in use far too long for some of these supposed origins to be possible.
A possible intermediate might be a Latin 4th-declension verbal noun *fūtus, with possible meanings including "act of (pro)creating".
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. According to linguist Pamela Hobbs, "notwithstanding its increasing public use, enduring cultural models that inform our beliefs about the nature of sexuality and sexual acts preserve its status as a vile utterance that continues to inspire moral outrage." Hobbs considers users rather than usage of the word and sub-divides users into 'non-users', for whom the word "evokes the core sexual meanings and associated sexual imagery that motivate the taboo", and 'users' for whom "metaphorical uses of the word fuck no more evoke images of sexual intercourse than a ten-year-old’s ‘My mom’ll kill me if she finds out’ evokes images of murder," so that the "criteria of taboo are missing." Because of its increasing usage in the public forum, in 2005 the word was included for the first time as one of three vulgarities in The Canadian Press's Canadian Press Caps and Spelling guide.
it is uncertain to what extent the word fuck was considered acceptable at the time.
The stem of fuccant is an English word used as Latin: English medieval Latin has many examples of writers using English words when they did not know the Latin word: "workmannus" is an example.
which often refers to the act of sexual intercourse but is also commonly used as an intensifier or to denote disdain.
Its origin is obscure but is usually considered to be first attested to around 1475, although it may be considerably older.
One reason that the word fuck is so hard to trace etymologically is that it was used far more extensively in common speech than in easily traceable written forms.
There are several urban-legend false etymologies postulating an acronymic origin for the word.
In the Middle English of this poem, the term wife was still used generically for "woman".
The word has probable cognates in other Germanic languages, such as German ficken (to fuck); Dutch fokken (to breed, to beget); dialectal Norwegian fukka (to copulate), and dialectal Swedish focka (to strike, to copulate) and fock (penis).
However, there is no clear past lineage or derivation for the Latin word.
