Perpetrate and perpetuate look almost the same, but one is about committing a crime and the other is about keeping something going. A thief perpetrates a robbery, while a tradition perpetuates a custom for generations. 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 perpetrate is to commit a crime or a wrong act — a robbery, a fraud, an attack. To perpetuate is to make something continue for a long time — a tradition, a myth, an injustice. So criminals perpetrate crimes, while stories and habits perpetuate ideas.

Perpetrate: The Commit-a-Crime Word

Perpetrate (pronounced “PUR-puh-trayt”) is a verb meaning to commit a crime, a harmful act, or something wrong. It is almost always used for bad deeds.

• The gang perpetrated a robbery at the bank last night.
• He was accused of perpetrating a fraud against the company.
• Who perpetrated this terrible attack on the village?

Perpetuate: The Keep-Going Word

Perpetuate (pronounced “pur-PET-yoo-ayt”) is a verb meaning to make something continue forever, or for a very long time. It can keep good things going, like traditions, or bad things, like myths and inequality.

• The festival perpetuates an old tradition of the village.
• These films perpetuate a false idea about the country.
• Unfair rules can perpetuate poverty for many years.

The Easy Trick to Remember

• Perpetrate has “tra” — like “traitor” and “crime”. Crimes are perpetrated by criminals.
• Perpetuate has “petu” — like “perpetual”, meaning never-ending. To perpetuate is to keep something going forever.
• Perpetrate is a single act; perpetuate is a long process — a robbery happens once, but a tradition continues for years.
• Say it as a rhyme: “Thieves perpetrate in the night, while old tales perpetuate wrong and right.”
