Hey Daniel, let me give you two sentences that will help you difference: 1. Please assure me that you will not run away once I fall asleep. 2. Ensure you close the door before going to sleep. I am Mirriam, an academic writer with over five years experience in handling research papers. I specialize in helping students with essays, exams, and any other academic assignments from any level.

To assure someone is to remove someone’s doubts. In other words, to tell someone that something will definitely happen or is definitely true so that they are less worried. Example: Her doctor has assured us that she’ll be fine. To ensure something is to make sure it happens—to guarantee it. Example: They want to ensure (=make sure/ make certain) that the building is safe before entering it. To insure something or someone is to cover it with an insurance policy. Example: Have you insured your car? Does it have insurance? Some people use assure, ensure, and insure interchangeably. All three verbs have something to do with “making sure” and are therefore similar, but each of them has a distinct meaning.

Assure means confirm Ensure means check The car mechanic assured me that he had checked the brakes on my car. It is very important to ensure that the brakes on your car are working well.

Great question! At first they seem like they mean the same thing, but personally, I use them in different ways. “I assure you that nothing is going to go wrong.” “I am going to ensure that everything goes according to plan”
