A delusion is commonly defined as a false belief, and is used in everyday language to describe a belief that is either false, fanciful or derived from deception. In psychiatry, the definition is necessarily more precise and implies that the belief is pathological (the result of an illness or illness process).

You will see that some definitions are of pathological conditions, others of common use.
