Delusion (Noun)

An idiosyncratic belief or impression maintained despite being contradicted by reality or rational argument, typically as a symptom of mental disorder: the delusion of being watched.

Origin: late Middle English (in the sense ‘act of deluding or of being deluded’): from late Latin delusio(n-), from the verb deludere (see delude).
