Etymology Origin:
The word traces back to Latin duplicitas (doubleness), which evolved into English "duplicity" (deceitfulness by pretending to act one way while behaving another). The adjective "duplicitous" emerged in the 19th century, directly linking to the concept of doubling—here, metaphorically representing hidden intentions behind a façade. The logic mirrors physical doubling (e.g., folding) applied to behavior, where actions and truths are "doubled" or concealed.
