  F \F\ ([e^]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 Ph[oe]nician,


        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,
        [sect][sect] 178, 179, 188, 198, 230.
