Need \Need\, v. t. [imp. & p. p. {Needed}; p. pr. & vb. n.
   {Needing}.] [See {Need}, n. Cf. AS. n?dan to force, Goth.
   nau?jan.]
   To be in want of; to have cause or occasion for; to lack; to
   require, as supply or relief.

         Other creatures all day long Rove idle, unemployed, and
         less need rest.                          --Milton.

   Note: With another verb, need is used like an auxiliary,
         generally in a negative sentence expressing requirement
         or obligation, and in this use it undergoes no change
         of termination in the third person singular of the
         present tense. ``And the lender need not fear he shall
         be injured.'' --Anacharsis (Trans. ).
