Probably the most used and common swear word is the F-Word (F**K). Many others as the M-Word (M*****F*****) derive or are complemented by the F-Word, and most of the others (like As*Ho*e) and (cu*t) have an actual meaning but have become swear words. So, the only interesting one to research is the F-Word. Here some theories about its origins: 1. The American Heritage Dictionary says its first known occurrence in English literature was in the satirical poem "Flen, Flyss" (c.1500), where it was not only disguised as a Latin word but encrypted — gxddbov — which has been deciphered as fuccant, pseudo-Latin for "they f**k." 2. When doctors wrote a diagnostic notation on the documests of soldiers in the British Imperial Army reporting sick and found to have Sexual Transmitted Diseases., the abbreviation F.*.*.K. was stamped on his documents. It was short for "Found Under Carnal Knowledge." 3. In the 15th Century, when a married couple needed permission from the king to procreate. Hence, "Fornication Under Consent of the King" (F.*.*.K.). 4. May be an acronym of a law term used in the 1500s that referred to rape as "Forced Unnatural Carnal Knowledge" (F.*.*.K.). 5. Referring to the charge for prostitution in England: "For Unlawful Carnal Knowledge (F.*.*.K.)." Interesting, isn't it?

why would no. 3 "Fornication Under Consent of the King" if the couple were married? It wouldn't be fornication then.
