Alpha \Al"pha\, n. [L. alpha, Gr. 'a`lfa, from Heb. [=a]leph,
   name of the first letter in the alphabet, also meaning ox.]
   The first letter in the Greek alphabet, answering to A, and
   hence used to denote the beginning.

         In am Alpha and Omega, the beginning and the end, the
         first and the last.                      --Rev. xxii.
                                                  13.

   Note: Formerly used also denote the chief; as, Plato was the
         alpha of the wits.

   Note: In cataloguing stars, the brightest star of a
         constellation in designated by Alpha ([alpha]); as,
         [alpha] Lyr[ae].

A \A\ (named [=a] in the English, and most commonly ["a] in
   other languages).
   The first letter of the English and of many other alphabets.
   The capital A of the alphabets of Middle and Western Europe,
   as also the small letter (a), besides the forms in Italic,
   black letter, etc., are all descended from the old Latin A,
   which was borrowed from the Greek {Alpha}, of the same form;
   and this was made from the first letter (?) of the
   Ph[oe]nician alphabet, the equivalent of the Hebrew Aleph,
   and itself from the Egyptian origin. The Aleph was a
   consonant letter, with a guttural breath sound that was not
   an element of Greek articulation; and the Greeks took it to
   represent their vowel Alpha with the ["a] sound, the
   Ph[oe]nician alphabet having no vowel symbols. This letter,
   in English, is used for several different vowel sounds. See
   Guide to pronunciation, [sect][sect] 43-74. The regular long
   a, as in fate, etc., is a comparatively modern sound, and has
   taken the place of what, till about the early part of the
   17th century, was a sound of the quality of ["a] (as in far).

   2. (Mus.) The name of the sixth tone in the model major scale
      (that in C), or the first tone of the minor scale, which
      is named after it the scale in A minor. The second string
      of the violin is tuned to the A in the treble staff. -- A
      sharp (A[sharp]) is the name of a musical tone
      intermediate between A and B. -- A flat (A[flat]) is the
      name of a tone intermediate between A and G.

   {A per se} (L. per se by itself), one pre["e]minent; a
      nonesuch. [Obs.]

            O fair Creseide, the flower and A per se Of Troy and
            Greece.                               --Chaucer.
