n. [ Gr. &unr_;, fr. &unr_; to keep in mind, consider; &unr_; in + &unr_; 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. [ 1913 Webster ]
