Yes, this is probably an Anglish word! ("Fuck" appears to have cognates in German and Dutch - ficken in German, fokken in Dutch, fukka in Norwegian, and focka in Swedish.) The earliest known appearance of "fuck", alas, may have been after it had already become obscene in polite circles - it appeared in a mixed English-Latin poem, "Flen flyys" (Fleas, Flies), in code. ("Non sunt in coeli" (Latin for "they are not in heaven"), "quia gxddbov xxkxzt pg ifmk" ("because "fuccant vvivys of heli" - "they fuck wives (women) of Ely").
While the "F" word is also somewhat similar to certain words in the Romance languages - futuere, foutre, fotre, fottere, futere, joder, and foder - this is a more distant relationship than with the German cognates. There is a theory out there that "fuck" is actually from other Germanic languages and not old English, though. Rickyrab (talk) 02:37, August 24, 2015 (UTC)
