- Same as Eisel.
F () 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
Phoenician, 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,
