Minor \Mi"nor\, n.
   1. A person of either sex who has not attained the age at
      which full civil rights are accorded; an infant; in
      England and the United States, one under twenty-one years
      of age.

   Note: In hereditary monarchies, the minority of a sovereign
         ends at an earlier age than of a subject. The minority
         of a sovereign of Great Britain ends upon the
         completion of the eighteenth year of his age.

   2. (Logic) The minor term, that is, the subject of the
      conclusion; also, the minor premise, that is, that premise
      which contains the minor term; in hypothetical syllogisms,
      the categorical premise. It is the second proposition of a
      regular syllogism, as in the following: Every act of
      injustice partakes of meanness; to take money from another
      by gaming is an act of injustice; therefore, the taking of
      money from another by gaming partakes of meanness.

   3. A Minorite; a Franciscan friar.

   Ir. & Gael. min small, tender, L. minuere to lessen, Gr. ?,

      of little account; as, minor divisions of a body.

   2. (Mus.) Less by a semitone in interval or difference of
      pitch; as, a minor third.

   {Asia Minor} (Geog.), the Lesser Asia; that part of Asia
      which lies between the Euxine, or Black Sea, on the north,
      and the Mediterranean on the south.

   {Minor mode} (Mus.), that mode, or scale, in which the third
      and sixth are minor, -- much used for mournful and solemn
      subjects.

   {Minor orders} (Eccl.), the rank of persons employed in
      ecclesiastical offices who are not in holy orders, as
      doorkeepers, acolytes, etc.

   {Minor scale} (Mus.) The form of the minor scale is various.
      The strictly correct form has the third and sixth minor,
      with a semitone between the seventh and eighth, which
      involves an augmented second interval, or three semitones,
      between the sixth and seventh, as, ^{6/F}, ^{7/G[sharp]},
      ^{8/A}. But, for melodic purposes, both the sixth and the
      seventh are sometimes made major in the ascending, and
      minor in the descending, scale, thus:
