          to extol is to bear aloft, to exalt. We may praise in
          the exercise of calm judgment; we usually applaud from
          impulse, and on account of some specific act; we extol
          under the influence of high admiration, and usually in
          strong, if not extravagant, language.

Praise \Praise\, n. [OE. preis, OF. preis price, worth, value,

            goodness with the practice.           --Rambler.

   Note: Praise may be expressed by an individual, and thus
         differs from fame, renown, and celebrity, which are
         always the expression of the approbation of numbers, or
         public commendation.

      rendered to the Divine Being; the act of glorifying or
      extolling the Creator; worship, particularly worship by

      as, a service of praise.
