1. The act of confining a person, esp. in a prison (the imprisonment of Jackson was entirely justified).
2. The state of being confined; a period of confinement (Jackson’s imprisonment lasted 14 years). See FALSE IMPRISONMENT.
“Imprisonment, by whatever name it is called, is a harsh thing, and the discipline that must be exercised over human beings in close confinement can never be wholly agreeable to those subject to it.

Fuller, Anatomy of the Law 57 (1968).
