self-deception

The word is a modern English compound, formed by combining the native English reflexive pronoun 'self' with the Latinate noun 'deception'. 'Self' originates from Proto-Germanic selbaz, carrying the core sense of one's own identity. 'Deception' traces back to the Latin verb decipere, meaning "to ensnare, to cheat," from de- (from, away) and capere (to take). The compound 'self-deception' logically builds on the classical concept of deception but turns the action inward. It describes the psychological process where an individual's mind "takes away" the truth from itself, creating a false belief for personal comfort, thus blending an ancient metaphor of capture with a modern understanding of internal psychological conflict.
