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.
  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.

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.
