V \V\ (v[=e]).
   1. V, the twenty-second letter of the English alphabet, is a
      vocal consonant. V and U are only varieties of the same
      character, U being the cursive form, while V is better
      adapted for engraving, as in stone. The two letters were
      formerly used indiscriminately, and till a comparatively
      recent date words containing them were often classed
      together in dictionaries and other books of reference (see
      {U}). The letter V is from the Latin alphabet, where it
      was used both as a consonant (about like English w) and as
      a vowel. The Latin derives it from it from a form (V) of
      the Greek vowel [Upsilon] (see {Y}), this Greek letter
      being either from the same Semitic letter as the digamma F
      (see {F}), or else added by the Greeks to the alphabet
      which they took from the Semitic. Etymologically v is most
      nearly related to u, w, f, b, p; as in vine, wine;
      avoirdupois, habit, have; safe, save; trover, troubadour,
      trope. See U, F, etc. See Guide to Pronunciation, [sect]
      265; also [sect][sect] 155, 169, 178-179, etc.

   2. As a numeral, V stands for five, in English and Latin.
