It’s my favorite word due to it’s versatility and Vanity Fair examines where the word “Fuck” originates:
Both verb and noun, infix and interjection, “fuck,” like many chimerical beasts, is of ill repute and unknown genesis. The American Heritage Dictionary, similar to its tweedier brother, the Oxford English Dictionary, is unable to divine the exact etymology of “fuck,” however it does provide information about its first known publication. Specifically, the word initially appeared in a satirical poem composed sometime around 1500 that takes aim at the Carmelite friars of Cambridge. Although the letters F, U, C, and K do not appear in their recognizable, rancorous order, they are expressed in a simple code that “is easily broken by simply substituting the preceding letter in the alphabet, keeping in mind differences in the alphabet and in spelling between then and now,” according to the dictionary. Drained of its cryptic Latin and less cryptic cryptology, “non sunt in coeli, quia gxddbov xxkxzt pg ifmk” begets “they are not in heaven because they fuck wives of Ely [a town near Cambridge].” For what it’s worth, the Online Dictionary of Etymology surmises that “fuck” has roots in the Middle English “fyke,” meaning to “move restlessly.” “Fyke” had sexual connotations, too; it suggested fidgeting as well as flirting, as the wives of Ely might attest.
If you ever doubted the gutteral elegance of the word “fuck”, then you should watch this scene from Season One of HBO’s The Wire. McNulty and Bunk use the word close to 40 times in just a few minutes.
