Unknown, but probably from Middle English *fucken, of North Germanic origin, related to dialectal Norwegian fukka ‎(to copulate; fuck), Bohuslän Swedish fokka (earlier "to fuck; thrust; push", nowadays focka ‎(to fire from work)), Swedish fock ‎(penis), and Middle Dutch (and Modern Dutch) fokken ‎(to breed). It may go back to the Proto-Indo-European *pug-, *puǵ- ("to strike"; source of Latin pugnus ‎(fist) among many others), or to Proto-Indo-European *puḱn-, *pewḱ- ("to sting, stick, stab"; compare German ficken ‎(to fuck)). The word may be attested in a 772 charter which mentions a place called Fuccerham, which possibly means “ham ‎(home) of the fucker” or “hamm ‎(pasture) of the fucker”. The earliest verifiable use of the word in an unambiguously sexual context in any stage of English appears in court documents from Chester county, England, which first mention a man called "Roger Fuckebythenavele" on December 8, 1310.[1][2] It was first listed in a dictionary in 1598.[3]

The Scots cognate, fuk, fuck, appears in 16th century sources,[4] the earliest being the 1503 poem “Brash of Wowing” by William Dunbar,[5] which includes the lines: “Yit be his feirris he wald haif fukkit: / Ye brek my hairt, my bony ane.”

A range of folk-etymological backronyms has been advanced, such as "fornication under consent of the king" and "for unlawful carnal knowledge", which are all demonstrably false.
