A plea bargain (also plea agreement, plea deal or copping a plea) is an agreement in a criminal case between the prosecutor  and defendant whereby the defendant agrees to plead guilty to a particular charge in return for some concession from the prosecutor. This may mean that the defendant will plead guilty to a less serious charge, or to one of several charges, in return for the dismissal of other charges; or it may mean that the defendant will plead guilty to the original criminal charge in return for a more lenient sentence.
