What is exorcism. The definition of exorcism.

exorcism (ĕk'sôrsĭz'əm) , ritual act of driving out evil demons or spirits from places, persons, or things in which they are thought to dwell. It occurs both in primitive societies and in the religions of sophisticated cultures. The term is applied to all those acts that seek to dispel or frighten away demons or spirits, as distinguished from those rites that aim at propitiating or evoking their assistance (see magic and shaman). Exorcism may be applied to a particular person or thing or may be used in a more general way. In central Europe during Walburga's night (or Walpurgishnacht, May 1), the traditional witches' sabbath, witches and demons are exorcised from the town by use of holy water, incense, and loud noises of all kinds. The scriptural justification for exorcism is found throughout the New Testament, and many instances of Jesus' ability to cast out devils are recorded.

Exorcism is the practice of evicting demons or other evil spiritual entities which are supposed to have possessed (taken control of) a person or object. The practice is quite ancient and still part of the belief system of many religions.
The person performing the exorcism, known as an exorcist, is often a priest, or an individual thought to be graced with special powers or skills. The exorcist may use religious material, such as prayers and set formulas, gestures, symbols, icons, amulets, etc.. The exorcist often invokes some benign supernatural power to actually perform the task.
In general, possessed persons are not regarded as evil in themselves, nor wholly responsible for their actions. Therefore, exorcism is generally thought more as a cure than as a punishment. However, the two concepts are often confused in practice, and exorcism has often been (ab)used as a pretext for harsh physical punishment, or even sadism.
