Chapeltown, Lancashire in the context of "West Pennine Moors"

Punishment, commonly, is the imposition of an undesirable or unpleasant outcome upon an individual or group, meted out by an authority—in contexts ranging from child discipline to criminal law—as a deterrent to a particular action or behavior that is deemed undesirable. It is, however, possible to distinguish between various different understandings of what punishment is.

The reasoning for punishment may be to condition a child to avoid self-endangerment, to impose social conformity (in particular, in the contexts of compulsory education or military discipline), to defend norms, to protect against future harms (in particular, those from violent crime), and to maintain the law—and respect for rule of law—under which the social group is governed. Punishment may be self-inflicted as with self-flagellation and mortification of the flesh in the religious setting, but is most often a form of social coercion.
