Section 44 of the Indian Penal Code, 1860, provides a very broad definition of the word "injury". It states: "The word 'injury' denotes any harm whatever illegally caused to any person, in body, mind, reputation or property." This definition is crucial because many offences in the IPC are defined by the causing of 'injury' or 'harm'. The definition makes it clear that injury is not limited to physical harm but also includes mental distress, damage to one's reputation (defamation), and loss of property.
