The letter F is the sixth letter in the Latin alphabet.
History
F developed from the digraph FH that stood for /f/.
The Etruscans were the inventors of this digraph; F on its own stood for /w/ in Etruscan as in Greek (where the letter F,called Digamma in Greek, has disappeared due to the fact that the /w/ phoneme itself disappeared.) The origin of F is the Semitic letter wâw that also represented /w/ and originally probably represented a hook or a club.
The miniscule f is not to be confused with ſ, the archaic long s (or medial s). For example, "sinfulness" is rendered as "ſinfulneſs" using the long s. The use of the long s died out by the end of the 19th century, largely to prevent confusion with f.
