Rehabilitation is an action that involves restoring something to its original state. It can be used to describe the process of restoring a person's health, ability to work, or reputation. It can also refer to the process of restoring a forest that has been cleared for use as an amusement park. The term “rehabilitate” comes from medieval Latin, where it was derived from the Latin words “re-” and “habilitare”, meaning “to habilitate”.
When used in relation to people, rehabilitation is the process of helping them regain their strength or learn to live without drugs or other addictive substances or behaviors. In legal terms, rehabilitation is also used to refer to the process of introducing evidence in court to restore a witness's character. There are several state and federal rules of evidence that govern what evidence is admissible for this purpose.
