40 Fantastic F-Words To Further Your Vocabulary
One of the earliest ancestors of our humble letter F was a Phoenician letter, waw, which was assimilated into the early Greek alphabet more than 2500 years ago. It’s thought that the Phoenicians used their letter waw to represent an array of different sounds—including “u,” “v,” and “w”—and as a result, when they adopted it, the ever-ingenious Greeks cleverly divided its use in two. On the one hand, the Greek letter upsilon (Y) took over the “u” and “v” sounds, while another letter, digamma (F), took over the “w” sound. Unfortunately, “w” (or rather, the labio-velar approximant, if you want to get technical) wasn’t the most widely used sound in Ancient Greek, and digamma soon fell out of use. But it was salvaged from the linguistic scrapheap by the Romans, whose Latin letter V took over where upsilon left off, leaving F to represent a newly-emerging softer “v” sound—“f.”
The letter F has remained in use in the Roman alphabet ever since, and it now accounts for on average around 2.5 percent of any page of written English—a figure boosted by its appearance in high-frequency words like for, if, from, and of (the only English word in which F is pronounced “v”). You can also expect it to begin around 3 percent of all the words in a standard dictionary, including the 40 fantastic F-words listed here…
A Latin word for “cleverness” or “skillfulness,” facetiae came to be used to refer to a collection of witty sayings in 16th-century English. But things took a turn for the worse in Victorian slang, when facetiae came to be used as a euphemism for pornographic literature.

Famble was a 16th-century word for a hand (probably originally derived from a slang mispronunciation of “fumble”), and from there the English language has gained a number of equally handy fam– words: On its own, a fam was a gold ring in 18th-century English; gloves were nicknamed fam-snatchers in 19th-century slang; among Victorian criminals, to fam-squeeze someone was to throttle them with your bare hands; and to famgrasp is to shake hands in agreement.

Fescennia was a city in Etruria, an ancient region of northern and central Italy occupied by the Etruscan civilization more than 2500 years ago. As the Roman Empire expanded outwards from Rome, it’s thought that a number of local Etruscan songs and poems were adopted into Roman culture in the process. These “Fescennine verses,” as they were known, were originally sung at harvest time or at large celebrations like weddings, but steadily they became less celebratory and ever more coarse and raucous. Ultimately, the adjective fescennine has ended up being used to describe anything obscene, lewd, or licentious.

Floccus (literally “a wisp”), naucum (“a trifle”), nihil (“nothing”), and pilus (“a hair”) are all Latin words that can be essentially interpreted as meaning “very little,” or “nothing at all.” The nonsense word floccinaucinihilipilification—apparently coined by students studying Latin at England’s famous Eton College—brings all four of them together in one noun, meaning “the act of estimating something as worthless.” Often considered one of the longest words in the English language and one of the longest words in most dictionaries, floccinaucinihilipilification is related etymologically to the 16th-century verb …
