Writing cursive forms of F

F (named ef /ˈɛf/) is the sixth letter in the modern English alphabet and the ISO basic Latin alphabet.

History

Proto-Semitic W	Phoenician  waw	Greek Digamma	Etruscan V or W	Roman F

The origin of 'F' is the Semitic letter vâv (or waw) that represented a sound like /v/ or /w/. Graphically it originally probably depicted either a hook or a club. It may have been based on a comparable Egyptian hieroglyph such as that which represented the word mace (transliterated as ḥ(dj)):

The Phoenician form of the letter was adopted into Greek as a vowel, upsilon (which resembled its descendant 'Y' but was also the ancestor of the Roman letters 'U', 'V', and 'W'); and with another form, as a consonant, digamma, which resembled 'F', but indicated the pronunciation /w/, as in Phoenician. (After /w/ disappeared from Greek, digamma was used only as a numeral.)

In Etruscan, 'F' probably represented /w/, as in Greek, and the Etruscans formed the digraph 'FH' to represent /f/. When the Romans adopted the alphabet, they used 'V' (from Greek upsilon) to stand for /w/ as well as /u/, leaving 'F' available for /f/. (At that time, the Greek letter phi 'Φ' represented an aspirated voiceless bilabial plosive /pʰ/, though in Modern Greek it approximates the sound of /f/.) And so out of the various vav variants in the Mediterranean world, the letter F entered the Roman alphabet attached to a sound which its antecedents in Greek and Etruscan did not have. The Roman alphabet forms the basis of the alphabet used today for English and many other languages.

The lowercase ' f ' is not related to the visually similar long s, ' ſ ' (or medial s). The use of the long s largely died out by the beginning of the 19th century, mostly to prevent confusion with ' f ' when using a short mid-bar (see more at: S).

Use in writing systems

English

In the English writing system ⟨f⟩ is used to represent the sound /f/, the voiceless labiodental fricative. It is commonly doubled at the end of words. Exceptionally, it represents the voiced labiodental fricative /v/ in the common word "of".

Other languages

In the writing systems of other languages, ⟨f⟩ commonly represents /f/, [ɸ] or /v/.

• In French orthography, ⟨f⟩ is used to represent /f/. It may also be silent at the end of words.
• In Spanish orthography, ⟨f⟩ is used to represent /f/. In standard speech this is realized as [f] but a common nonstandard pronunciation is [ɸ]. It may merge with /x/ before /w/ in some dialects. See Spanish phonology.
• In the Hepburn romanization of Japanese, ⟨f⟩ is used to represent [ɸ]. This sound is usually considered to be an allophone of /h/, which is pronounced in different ways depending upon its context; Japanese /h/ is pronounced as [ɸ] before /u/.
• In Welsh orthography, ⟨f⟩ represents /v/ while ⟨ff⟩ represents /f/.
• In Slavic languages, ⟨f⟩ is used primarily in words of foreign (Greek, Latin, or Germanic) origin.

Other systems

The International Phonetic Alphabet uses ⟨f⟩ to represent the voiceless labiodental fricative.

Other uses

In English-language online slang, "F" (with the pronunciation spelling eff) is used as an initialism for fuck. (e.g. F U, meaning fuck you). The F-word refers to the word fuck itself.
