\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.
