Will \Will\, v. i.
   To be willing; to be inclined or disposed; to be pleased; to
   wish; to desire.

         And behold, there came a leper and worshiped him,
         saying, Lord if thou wilt, thou canst make me clean.
         And Jesus . . . touched him, saying, I will; be thou
         clean.                                   --Matt. viii.
                                                  2, 3.

   Note: This word has been confused with will, v. i., to
         choose, which, unlike this, is of the weak conjugation.

   {Will I, nill I}, or {Will ye, hill ye}, or {Will he, nill
   he}, whether I, you, or he will it or not; hence, without
      choice; compulsorily; -- sometimes corrupted into willy
      nilly. ``If I must take service willy nilly.'' --J. H.
      Newman. ``Land for all who would till it, and reading and
      writing will ye, nill ye.'' --Lowell.
