“Ensure” vs. “Insure” vs. “Assure”
There’s a bit of an overlap when it comes to ensure, insure, and assure.

However, that doesn’t necessarily mean these words can be interchanged. There are certain scenarios and definitions that are attributed more to one word over the other two. Below, we’ll go over the differences between ensure, insure, and assure and teach you how to use these words correctly.
What Does “Ensure” Mean?
Ensure means “to make sure or guarantee that something will (or will not) happen.” Here are a few examples of ensure in a sentence:
What Does “Insure” Mean?
The confusion mostly arises with ensure /ɪnˈʃʊr/ and insure /ɪnˈʃʊr/ because they are homophones—words that are pronounced the same but have different meanings.
Insure means to “protect someone or something financially with an insurance policy.” In other words, if you insure someone or something with a policy, that insurance company will compensate you if something were to happen.
What Does “Assure” Mean?
Assure /əˈʃʊr/ means “to remove doubt” or “to give confidence” to someone (or other living creature).
It is worth noting that British English sometimes uses assurance to refer to insurance, more specifically life insurance.
