Enthymeme \En"thy*meme\, n. [Gr. ?, fr. ? to keep in mind,
   consider; ? in + ? mind, soul.] (Logic)
   An argument consisting of only two propositions, an
   antecedent and consequent deduced from it; a syllogism with
   one premise omitted; as, We are dependent; therefore we
   should be humble. Here the major proposition is suppressed.
   The complete syllogism would be, Dependent creatures should
   be humble; we are dependent creatures; therefore we should be
   humble.
