How to Remember What duplicity Means
The idea of doubleness is at the core of duplicity. Duplicity 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 that 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.
— Proverbs 11:3 (New International Version)

Did You Know?
If someone's duplicity has left you feeling like you're seeing double, take heart in the word's etymology. Duplicity comes from a long line of "double" talk, starting with its Latin grandparent duplex, which means "double" or "twofold." As you might expect, duplex is also the parent of another term for doubling it up, duplicate. And of course, the English duplex (which can be a noun meaning "a two-family house" or an adjective meaning "double") comes from the Latin word of the same spelling.
