Brocard \Broc"ard\, n. [Perh. fr. Brocardica, Brocardicorum
   opus, a collection of ecclesiastical canons by Burkhard,
   Bishop of Worms, called, by the Italians and French,
   Brocard.]
   An elementary principle or maximum; a short, proverbial rule,
   in law, ethics, or metaphysics.

         The legal brocard, ``Falsus in uno, falsus in
         omnibus,'' is a rule not more applicable to other
         witness than to consciousness.           --Sir W.
                                                  Hamilton.
