Assure Ensure and Insure

Assure, ensure, and insure are three English words that sound alike, are spelled alike, but have completely different meanings.

You’re not alone when it comes to the challenge that assure vs. ensure vs. insure seems confusing. Since all three terms have something to do with being sure, it’s clear why these word triplets are commonly confused in the English language. In fact, many people think that they’re simply interchangeable. 

Since they are homophones, they sound similar but are spelled differently, only adding to the confusion.

But they are three different terms with distinct meanings and uses. For that reason, it’s important to know the difference and how to use these commonly confused words correctly.
