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 a Greek digamma, which probably had the value of English w consonant. The form and value of Greek letter came from the Phoenician, the ultimate source being probably Egyptian. Etymologically f is most closely related to p, k, v, and b; as in E. five, Gr. pente; E. wolf, L. lupus, Gr. lykos; E. fox, vixen; fragile, break; fruit, brook, v. t.; E. bear, L. ferre.
