Origin: 1495–1505; akin to Middle Dutch fokken to thrust, copulate with, Swedish dialect focka to copulate with, strike, push, fock penis "They [the monks] are not in heaven because they fuck the wives of Ely." Fuccant is pseudo-Latin, and in the original it is written in cipher. The earliest examples of the word otherwise are from Scottish, which suggests a Scandinavian origin, perhaps from a word akin to Norw. dial. fukka "copulate," or Swedish dial. focka "copulate, strike, push," and fock "penis." Another theory traces it to M.E. fkye, fike "move restlessly, fidget," which also meant "dally, flirt," and probably is from a general North Sea Gmc. word, cf. M.Du. fokken, Ger. ficken "fuck," earlier "make quick movements to and fro, flick," still earlier "itch, scratch;" the vulgar sense attested from 16c. This would parallel in sense the usual M.E. slang term for "have sexual intercourse," swive , from O.E. swifan "to move lightly over, sweep" (see swivel). Chronology and phonology rule out Shipley's attempt to derive it from M.E. firk "to press hard, beat." As a noun, it dates from 1680. French foutre and Italian fottere look like the English word but are unrelated, derived rather from L. futuere , which is perhaps from PIE base *bhau(t)- "knock, strike off," extended via a figurative use "from the sexual application of violent action" [Shipley; cf. the sexual slang use of bang , etc.]. Popular and Internet derivations from acronyms (and the "pluck yew" fable) are merely ingenious trifling. The O.E. word was hæman , from ham "dwelling, home," with a sense of "take home, co-habit." Fuck was outlawed in print in England (by the Obscene Publications Act, 1857) and the U.S. (by the Comstock Act, 1873). The word may have been shunned in print, but it continued in conversation, especially among soldiers during WWI.
