Defamation is one of the verbal offences in which the plaintiff is accused of a certain wrongful act by one of the ways of publicity. If that wrongful act is proved, then the accused will be punished by law or lowered by his/her home people. Defamation is surely accusing another person of a wrongful act . Accusing can be done by any spoken or written ways whether truthful or doubtful. The purpose beyond those ways is to make those accusations about the victim true in the people's mind even if they are temporarily made.
