Displacement (German Verschiebung, 'shift' or 'move') is an unconscious defense mechanism whereby the mind redirects effects from an object felt to be dangerous or unacceptable to an object felt to be safe or acceptable. The term originated with Sigmund Freud.

Displacement operates in the mind unconsciously and involves emotions, ideas, or wishes being transferred from their original object to a more acceptable substitute. It is most often used to allay anxiety; and can to the displacement of aggressive impulses or to the displacement of sexual impulses...

In 1957, Jacques Lacan - building on the way in Freud's work, condensation (from German Verdichtung) and displacement are closely linked concepts, and inspired by an article by linguist Roman Jakobson - argued that the unconscious has the structure of a language, and that condensation and displacement are close equivalents to the poetic functions o fmetaphor and metonymy. As he cautiously put it, 'in the case of Verschiebung, "displacement", the German term is closer to the idea of that veering off of signification that we see in metonymy, and which from its first appearance in Freud is represented as the most appropriate means used by the unconscious to foil censorship'.
