     to each, single. Cg. Single, a., Same, a., and for the
     last part of the word cf. Double, Complex.]

         [1913 Webster]

           decomposed. There are indications that many of our

           actual decomposition into anything simpler may never be

        the parties, or is not to become void on the happening of
        any such event. --Burrill.
        [1913 Webster]
  
     Syn: Single; uncompounded; unmingled; unmixed; mere;
          uncombined; elementary; plain; artless; sincere;
          harmless; undesigning; frank; open; unaffected;
          inartificial; unadorned; credulous; silly; foolish;
          shallow; unwise.
  
     Usage: Simple, Silly. One who is simple is sincere,
            unaffected, and inexperienced in duplicity, -- hence
            liable to be duped. A silly person is one who is
            ignorant or weak and also self-confident; hence, one
            who shows in speech and act a lack of good sense.
            Simplicity is incompatible with duplicity, artfulness,
            or vanity, while silliness is consistent with all
            three. Simplicity denotes lack of knowledge or of
            guile; silliness denotes want of judgment or right
            purpose, a defect of character as well as of
            education.
            [1913 Webster]
  
                  I am a simple woman, much too weak
                  To oppose your cunning.           --Shak.
            [1913 Webster]
  
                  He is the companion of the silliest people in
                  their most silly pleasure; he is ready for every
                  impertinent entertainment and diversion. --Law.
            [1913 Webster]
