What does dissembler mean?
A dissembler is someone who deliberately conceals their true feelings, motives, or character while presenting a false appearance to others. The word derives from the verb 'dissemble', which combines the prefix 'dis-' with a root related to 'semblance' — literally meaning to hide one's real self beneath a different semblance. A dissembler may flatter insincerely, mask hostility with courtesy, or feign innocence while harbouring guilty intent. The term is formal or literary in register and carries strongly negative connotations: unlike a liar, who simply states falsehoods, a dissembler's deception lies in performance and concealment. It appears frequently in discussions of politics, diplomacy, court intrigue, and literature, where characters like Shakespeare's Iago are often described as masterful dissemblers. Because it names a specific and enduring human vice — the gap between outward show and inner reality — it remains a precise and useful word for describing hypocrisy of a calculated, sustained kind.

Etymology of dissembler
Dissembler comes from the verb 'dissemble', which entered English in the late Middle Ages (attested from the early 15th century), derived from Old French 'dessembler' or directly from Latin roots: 'dis-' (apart) plus 'simulare' (to simulate, pretend), the same root that gives us 'simulate', 'semblance', and 'similar'. The noun 'dissembler' followed naturally as an agent noun denoting one who practises such concealment. Its cognates share this Latin root of pretending or likeness, tying the word to a family of terms about appearances versus reality.
