Assure, ensure, and insure

Assure, ensure, and insure

Assure is the only one of the three words that means “to reassure someone or to promise.” أكّد  تعهد؛ طمئن

I assure you that the chocolate is fresh.

Ensure chiefly means “to make certain or to guarantee.” ضمن  أكَّد

He must ensure that the effect is eye-popping.

Insure can be interchangeable with ensure in some cases, but it is easiest to keep these words straight by reserving insure for references to insurance. أَمَّنَ

I need to insure my car.

The definitions are different in British English: in Britain, assure can mean “to insure against a loss.”
