Laconic \La*con"ic\, Laconical \La*con"ic*al\, a. [L. Laconicus
   Laconian, Gr. ??, fr. ?? a Laconian, Laced[ae]monian, or
   Spartan: cf. F. laconique.]
   1. Expressing much in few words, after the manner of the
      Laconians or Spartans; brief and pithy; brusque;
      epigrammatic. In this sense laconic is the usual form.

            I grow laconic even beyond laconicism; for sometimes
            I return only yes, or no, to questionary or
            petitionary epistles of half a yard long. --Pope.

            His sense was strong and his style laconic.
                                                  --Welwood.

   2. Laconian; characteristic of, or like, the Spartans; hence,
      stern or severe; cruel; unflinching.

            His head had now felt the razor, his back the rod;
            all that laconical discipline pleased him well.
                                                  --Bp. Hall.

   Syn: Short; brief; concise; succinct; sententious; pointed;
        pithy.

   Usage: {Laconic}, {Concise}. Concise means without irrelevant
          or superfluous matter; it is the opposite of diffuse.
          Laconic means concise with the additional quality of
          pithiness, sometimes of brusqueness.
