Latin term for duplicity; deceitfulness, dishonesty, or the practice of double-dealing.
Directly from Latin 'duplicitas', derived from 'duplex' (double). The literal meaning 'doubleness' evolved metaphorically to mean 'double-dealing' or saying one thing while meaning another.
The word 'duplicity' literally means 'two-foldedness'—your words fold one way, your intentions another. Romans understood that deception comes from a divided mind, which is why they used the 'duplex' root!
