Profuse \Pro*fuse"\, a. [L. profusus, p. p. of profundere to

   F. profus. See {Fuse} to melt.]
   1. Pouring forth with fullness or exuberance; bountiful;
      exceedingly liberal; giving without stint; as, a profuse
      government; profuse hospitality.

            A green, shady bank, profuse of flowers. --Milton.

   2. Superabundant; excessive; prodigal; lavish; as, profuse
      expenditure. ``Profuse ornament.'' --Kames.

   Syn: Lavish; exuberant; bountiful; prodigal; extravagant.

   Usage: {Profuse}, {Lavish}, {Prodigal}. Profuse denotes
          pouring out (as money, etc.) with great fullness or
          freeness; as, profuse in his expenditures, thanks,
          promises, etc. Lavish is stronger, implying
          unnecessary or wasteful excess; as, lavish of his
          bounties, favors, praises, etc. Prodigal is stronger
          still, denoting unmeasured or reckless profusion; as,

          some object. --Dryden.
