A person who conceals their true feelings, intentions, or character; someone who is deceptive or hypocritical.
From Old French 'dissembler' plus agent suffix '-er.' This term dates to the 16th century and describes someone who deliberately hides their true self.
History's greatest 'dissemblers' were spies and courtiers—people like Cardinal Richelieu who had to hide their ambitions behind charming smiles while secretly manipulating kings.
