delusion


delusion
delusion, illusion
overlap in meaning because both are to do with things wrongly believed or thought for various reasons. There is, however, a distinguishing principle: a delusion is a wrong belief regarded from the point of view of the person holding it (and has special uses in psychiatry, as in delusions of grandeur), whereas an illusion is a wrong belief or impression regarded externally. Delusion, unlike illusion, has a corresponding verb, delude, and the action of this verb is sometimes implicit in the choice between delusion and illusion. The following examples will help to clarify these points: (delusion)
