It is related to words in several other Germanic languages, such as Dutch, German, and Swedish, that have sexual meanings as well as meaning such as ‘to strike’ or ‘to move back and forth’.” 
 
 Dr Paul Booth is the Honouray Senior Research Fellow in History at Keele University and Co-Director of the Arts and Humanities Research Council Project: Gascon Rolls, 1317-1468. According to Themedievalists.org "fuck" popped up seemingly by accident in 1278 as part of a translation of the German word "fulcher," meaning soldier. This, on the other hand, would be the first instance of the word being used the way we use it today, beating out recent discoveries like the one from around 1475, or one found last year from 1528. The man was being named three times part of a process to be outlawed, with the final mention coming on September 28, 1311. By 
 
 An English historian has come across the word ‘fuck’ in a court case dating to the year 1310, making it the earliest known reference to the swear word. First, that it applies to an actual event—a clumsy attempt at sexual intercourse by an 'Inexperienced Copulator' (my name for Roger), revealed to the world by a revengeful former girlfriend.
– What's in a name? Just a crass term that's endured for centuries, if this holds any water. An English history researcher says he's spotted the earliest-known "f-word" on record in court documents from 1310, the Telegraph reports. Paul Booth came upon a reference to "Roger F***ebythenavele"—likely the guy's nickname, Booth says—while analyzing court records during the stormy rule of Edward II (1307-27). The name is "written clearly, and three times, and I think that shows it's not a joke," says Booth. Looks like F***ebythenavele was summoned twice to court in Cheshire, in December of 1310 and May of 1311, and finally outlawed on September 28, 1311. A court clerk might have altered the guy's name for fun, Booth admits, but short of that he sees two explanations. "First, that it applies to an actual event—a clumsy attempt at sexual intercourse by an 'Inexperienced Copulator' (my name for Roger), revealed to the world by a revengeful former girlfriend," he tells Vice.com. "Fourteenth-century revenge porn perhaps?" Or it might be an "elaborate way of describing someone regarded as a 'halfwit'—ie, that is the way that he would think of performing the sexual act." Before this, the earliest f-word on record was the phrase (translated from a Latin/English mix) "…they f**k the wives of Ely" from the poem "Flen flyys," circa 1475, Medievalists.net reports. The word has Germanic roots and is related to words that have "sexual meanings as well as meaning[s] such as 'to strike' or 'to move back and forth,'" writes Jesse Sheidlower in his book The F Word.
