Imprisonment (from imprison, via French emprisonner, originally from Latin prensio, arrest, from prehendere, prendere, "to seize") in law is the specific state of being physically incarcerated or confined in an institutional setting such as a prison. Courts of the United States, including the U.S. Supreme Court, have recognized that the minimum period in an indeterminate sentence that was actually imposed by a court of law is the official term of imprisonment. In other words, any "street time" (e.g., probation, parole, or supervised release) that was ordered by the court as part of the defendant's punishment does not constitute term of imprisonment.
