The Double Nature of Duplicity and Duplicitous
The idea of doubleness is at the core of duplicity and duplicitous. Duplicity is the older of the pair; it comes from a Latin word meaning "double" or "twofold," and its original meaning in English has to do with a kind of deception in which you intentionally hide your true feelings or intentions behind false words or actions. If you are being duplicitous there are two yous: the one you're showing and the one you're hiding. And—key to the idea of duplicity—you're hiding the hidden you in order to make people believe something that's not true.
The word is found in many works of literature, including the Bible:
The integrity of the upright guides them, but the unfaithful are destroyed by their duplicity.

— Tobias Wolff, Old School, 2003
