Persecute and prosecute sound very similar, but one is about cruelty and the other is about the law. To persecute someone is to harass and oppress them, while to prosecute someone is to bring them to court for a crime. This simple guide will help you tell them apart with easy examples, a memory trick, and a mini quiz.

What Is the Simple Difference?
The simple difference is this: to persecute is to treat someone cruelly and unfairly over a long time because of their religion, race, or beliefs. To prosecute is to bring legal charges against someone in a court of law. So a cruel ruler persecutes a minority group, but a state lawyer prosecutes a thief.
Persecute: The Oppress Word
Persecute (pronounced “PUR-sih-kyoot”) is a verb meaning to harass, oppress, or treat someone cruelly, usually because of who they are or what they believe. The noun is “persecution”.
- The cruel king persecuted people of a different faith.
- Many families fled the country to escape persecution.

Prosecute: The Court Word
Prosecute (pronounced “PROS-ih-kyoot”) is a verb meaning to bring someone to court and try to prove they are guilty of a crime. The lawyer who does this is called the “prosecutor”.
- The state will prosecute the man for theft.

The Easy Trick to Remember

- Persecute is cruel; prosecute is legal — one is a crime, the other is the law’s answer to a crime.
- Say it as a rhyme: “Tyrants persecute and cause pain, while the courts prosecute and try again.”
