The letter F traces its origins back to the Phoenician letter waw, which was integrated into the early Greek alphabet over 2500 years ago. The Phoenicians used waw to represent various sounds, such as “u,” “v,” and “w.” When the Greeks adopted it, they ingeniously split its usage. The Greek letter upsilon (Y) handled the “u” and “v” sounds, while digamma (F) took on the “w” sound. However, since the “w” sound was less common in Ancient Greek, digamma eventually faded. The Romans revived it, with their Latin letter V continuing upsilon’s role, while F evolved to represent the softer “f” sound.
Since then, the letter F has been a staple of the Roman alphabet. Today, it makes up approximately 2.5% of written English, thanks to its presence in common words like for, if, from, and of (the sole English word where F is pronounced as “v”). It also starts around 3% of all dictionary entries, including the 40 remarkable F-words listed here…
1. Facetiae
Derived from Latin, facetiae originally meant “cleverness” or “skillfulness.” By the 16th century, it referred to collections of humorous or witty remarks. However, during the Victorian era, the term took on a more scandalous meaning, becoming a euphemism for pornographic material.

The 16th-century word famble, likely a slang variation of “fumble,” referred to a hand.
