Final answer:
An accomplice is someone who aids, abets, advises, and/or encourages the actual perpetrator in a crime.
Step-by-step explanation:
The term that describes someone who aids, abets, advises, and/or encourages the actual perpetrator in a crime is accomplice.
An accomplice is someone who actively participates in the commission of a crime by assisting the main perpetrator. They may provide assistance before, during, or after the crime, and their actions contribute to the success of the criminal act.
For example, if someone helps plan a bank robbery, provides getaway transportation, or advises the main perpetrator on how to carry out the crime, they would be considered an accomplice. The level of involvement and intent of the accomplice can impact the charges and potential penalties they may face.
