Etymology
The word 'duplicity' traces its lineage to the Latin duplicitas, meaning "doubleness," which itself derives from duplex (twofold). The core root duplic- originates from the Proto-Indo-European compound dwo- (two) and plek- (to fold), literally meaning "twofold." This concrete notion of physical doubling evolved in Latin to encompass a metaphorical sense of deceptive doubleness of mind or character. In English, this abstract meaning of deceitful double-mindedness became the primary sense, while the original sense of simple doubleness became archaic, illustrating how a literal physical description transformed into a psychological and moral concept.
