f is a labiodental fricative, air being pushed through the upper teeth and lower lip: fún, féather, férry, fîght, forty, fífty, fílth, fíckle, fád, flóp, frét, físt, óff, óften (*offen), fát, fïrst, déaf, friénd. It is an unvoiced v: feŵ and vieŵ are a minimal pair.

• The accents show stress and pronunciation (see English spellings): A: sát, mâde, pàrk, cāst (cást/càst), åll, ãir; E: ére, êar, vèin, fërn; I: sít, mîne, skì, bïrd; O: sóng, môde, lòve, wörd, ŏr; OO: moôn, foòt; U: sún, mûse, fùll, pürr; W: neŵ, ẁant; Y: gým, mŷ, keỳ, mÿrrh.

It is often doubled at the end of words, after a single vowel letter: óff, stúff, clíff, whíff, múff, though not always: íf, óf (*ov), déaf (two vowel letters). And also in the middle of words: ráffle, óffer, íffy, báffle, éffort, Clífford, múffle, stúffing, stúffed.

f begins consonant clusters: Áfghan, aflôat, frîght, shíft.

The f sound, however, is spelt ph in many words from Greek: epíphany, Dáphne, grāph, élephant (though Stêphen is pronounced the same as Stêven).

In some words the f sound is written gh: enoúgh, tróugh, cóugh.

In óf and Welsh words such as eistéddfod (-édhvod) and Aberfán, single f is pronounced as v.
