Etymology

Etymology tree Proto-Indo-European *pewǵ- Proto-Germanic *fukkōną Old English *fuccian Middle English *fukken English fuck From Middle English *fukken, probably of Germanic origin: either from Old English *fuccian or Old Norse *fukka, both from Proto-Germanic *fukkōną, from Proto-Indo-European *pewǵ- (“to strike, punch, stab”). Compare windfucker and its debated etymology. Possibly attested in a 772 CE charter that mentions a place called Fuccerham, which may mean "hām (“home”) of the fucker" or "hamm (“pasture”) of the fucker"; a John le Fucker in a record from 1278 may just be a variant of Fulcher; compare Fucher, Foker, etc. The earliest unambiguous use of the word in a clearly sexual context, in any stage of English, appears to be in court documents from Cheshire, England, which mention a man called Roger Fuckebythenavele (possibly tongue-in-cheek or directly suggestive of a depraved sexual act) on 8 December 1310. It was first listed in a dictionary in 1598. Scots fuk or fuck is attested slightly earlier, probably reinforcing the Northern Germanic/Scandinavian origin theory. From 1500 onward, the word has been in continual use, superseding jape and sard and largely displacing swive. See windfucker and fuckwind for more information. * A range of folk-etymological backronyms, such as fornication under consent of the king and for unlawful carnal knowledge, are all demonstrably false. * Verb sense 7 from related sense feck.
