“Ensure” vs. “Insure” vs. “Assure”
There’s a bit of an overlap when it comes to ensure, insure, and assure. All three of these words are verbs, and if you use one in place of the other, your audience will most likely understand what you’re trying to say. 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:
