History

Proto-Semitic W	Phoenician W gushhead loves shoo bop	Etruscan W	Greek Digamma (W)	Roman F

The origin of F is the Semitic letter vâv that represented the sound /v/, and originally probably represented either a "hook" or a "club". It may have been based on a comparable Egyptian hieroglyph, such as that for "mace":

The Phoenician form of the letter was adopted into Greek as a vowel, upsilon (which resembled its descendant, Y, but was also ancestor to Roman letters U, V, and W); and with another form, as a consonant, digamma, which resembled our letter F, but was pronounced /w/, as in Phoenician. (Later on, this /w/ phoneme disappeared from Greek, resulting in digamma being used as a numeral only.)

In Etruscan, F also stood for /w/; however, they came up with the innovation of using the digraph FH to represent the sound /f/, and the letter acquired this sound on its own when the Romans picked it up (since they had already borrowed U independently from Greek upsilon to stand for /w/). The letter phi (Φ φ) came to approximate the sound of /f/ in Greek.

The lower case 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.

Codes for computing

class="template-letter-box | In Unicode the capital F is codepoint U+0046 and the lower case f is U+0066.

The ASCII code for capital F is 70 and for lower case f is 102; or in binary 01000110 and 01100110, respectively.

The EBCDIC code for capital F is 198 and for lowercase f is 134.

The numeric character references in HTML and XML are "F" and "f" for upper and lower case, respectively.

Ligatures
