A Grammar Girl Lesson

Assure Versus Ensure Versus Insure• Assure, ensure, and insure have the same

underlying meaning, but they each have a slightly different use.• Assure is the only one of the three words that

means “to reassure someone or to promise.”• I assure you the chocolate is fresh.

Ensure

• Ensure chiefly means “to make certain or to guarantee.”• He must ensure that the effect is eye-popping.

Insure

• Insure can be interchangeable with ensure in some cases, but it is easier to keep these words straight by reserving insure for references to insurance.• I need to insure my car.
