Definition - What does Plead mean?
To "plead" means to give a response to an accusation made by a plaintiff in a court of law. Typically, a defendant will plead either guilty or not guilty. Depending on how the defendant pleads, his or her defense will be set up differently. Guilty pleas and non-guilty pleas usually require different strategies.
Justipedia explains Plead
If a defendant pleads not guilty, then his or her defense will likely be arranged to try to prove that he or she is innocent. This could be in a criminal or civil case. The accusation could be anything from first-degree murder to violating traffic laws. However, if the defendant pleads guilty, then his or her defense will likely be arranged around trying to get as gentle a sentence as possible and to end the trial without any further problems.
