   {Jading}.]
   1. To treat like a jade; to spurn. [Obs.] --Shak.

   2. To make ridiculous and contemptible. [Obs.]

            I do now fool myself, to let imagination jade me.

   3. To exhaust by overdriving or long-continued labor of any
      kind; to tire or wear out by severe or tedious tasks; to
      harass.

            The mind, once jaded by an attempt above its power,
            . . . checks at any vigorous undertaking ever after.
                                                  --Locke.

   Syn: To fatigue; tire; weary; harass.

   Usage: To {Jade}, {Fatigue}, {Tire}, {Weary}. Fatigue is the
          generic term; tire denotes fatigue which wastes the
          strength; weary implies that a person is worn out by
          exertion; jade refers to the weariness created by a
          long and steady repetition of the same act or effort.
          A little exertion will tire a child or a weak person;
          a severe or protracted task wearies equally the body
          and the mind; the most powerful horse becomes jaded on
          a long journey by a continual straining of the same
          muscles. Wearied with labor of body or mind; tired of
          work, tired out by importunities; jaded by incessant
          attention to business.
