   1. The state or quality of being hidden; as, his movements
      were detected in spite of their secrecy.

            The Lady Anne, Whom the king hath in secrecy long
            married.                              --Shak.

      forbearance of disclosure or discovery.

            It is not with public as with private prayer; in
            this, rather secrecy is commanded than outward show.
