Alleviate \Al*le"vi*ate\, v. t. [imp. & p. p. {Alleviated}; p.

   levis light. See {Alegge}, {Levity}.]
   1. To lighten or lessen the force or weight of. [Obs.]

   Syn: To lessen; diminish; soften; mitigate; assuage; abate;
        relieve; nullify; allay.

   Usage: To {Alleviate}, {Mitigate}, {Assuage}, {Allay}. These
          words have in common the idea of relief from some
          painful state; and being all figurative, they differ
          in their application, according to the image under
          which this idea is presented. Alleviate supposes a
          load which is lightened or taken off; as, to alleviate
          one's cares. Mitigate supposes something fierce which
          is made mild; as, to mitigate one's anguish. Assuage
          supposes something violent which is quieted; as, to
          assuage one's sorrow. Allay supposes something
          previously excited, but now brought down; as, to allay
          one's suffering or one's thirst. To alleviate the
          distresses of life; to mitigate the fierceness of
          passion or the violence of grief; to assuage angry
          feeling; to allay wounded sensibility.
