  Dis·sem·bler n. One who dissembles; one who conceals his opinions or dispositions under a false appearance; a hypocrite.
     It is the weakest sort of politicians that are the greatest dissemblers.   --Bacon.
     Priests, princes, women, no dissemblers here.   --Pope.
  Syn: -- Dissembler, Hypocrite.
  Usage: A person is called a dissembler with reference to his concealment of his real character, and a hypocrite with reference to his assumption of a false character. But hypocrite is the stronger word, being commonly used to characterize a person who is habitually insincere and false, especially one who makes professions of goodness when his aims are selfish and his life corrupt.
