 F
 1. F is the sixth letter of the English alphabet, and a nonvocal consonant. Its form and sound are from the Latin. The Latin borrowed the form from the Greek digamma ░, which probably had the value of English w consonant. The form and value of Greek letter came from the Phœnician, the ultimate source being probably Egyptian. Etymologically f is most closely related to p, k, v, and b; as in E. five, Gr. pe`nte; E. wolf, L. lupus, Gr. ly`kos; E. fox, vixen ; fragile, break; fruit, brook, v. t.; E. bear, L. ferre. See Guide to Pronunciation, §§ 178, 179, 188, 198, 230.
 2. Mus. The name of the fourth tone of the model scale, or scale of C. F sharp (F ♯) is a tone intermediate between F and G.
 F clef, the bass clef. See under Clef.
