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 phoenician,
      the ultimate source being probably egyptian.

      ly`kos; e. fox, vixen; fragile, break; fruit, brook, v.
