The line that contains fuck reads Non sunt in coeli, quia gxddbov xxkxzt pg ifmk.
There are many common phrases that employ the word, as well as compounds that incorporate it, such as motherfucker, fuckwit and fucknut.
which refers to the act of sexual intercourse and 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.
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.
Journalists were advised to refrain from censoring the word but use it sparingly and only when its inclusion was essential to the story.
The Oxford English Dictionary states that the ultimate etymology is uncertain, but that the word is "probably cognate" with a number of native Germanic words with meanings involving striking, rubbing, and having sex or is derivative of the Old French word that meant "to fuck". Paul Booth claimed to have found "(possibly) the earliest known use of the word 'fuck' that clearly has a sexual connotation": in English court records of 1310–11, a man local to Chester is referred to as "Roger Fuckebythenavele", probably a nickname.
"Either this refers to an inexperienced copulator, referring to someone trying to have sex with the navel, or it's a rather extravagant explanation for a dimwit, someone so stupid they think this that is the way to have sex," says Booth.
An earlier name, that of John le Fucker recorded in 1278, has been the subject of debate, but is thought by many philologists to have had some separate and non-sexual origin.
