Hi Iena, They are all different verbs! Here are the definitions and some examples for each of them: 1. When you insure something, you pay money to a company so that if something happens to the item, you will get some compensation(money). For example, if you have an expensive phone like the Iphone 7, you will probably buy phone insurance. So if you broke your phone or dropped it in water, you would be able to get some money to replace the phone. Similarly you could buy home insurance and even life insurance. 2. Ensure is another way to say 'make sure'. For example, when you visit another country, you must ensure that you have a visa and a valid passport. 3. Assure is to tell someone that they do not need to worry or doubt something. The object should be a person. For example, when my son heard lightening for the first time, he was very scared. I assured him that everything was okay. I hope this helps. Let me know if you have any questions. I am available on instant tutoring if you would like to discuss these words or any other words more!

If something is "insured" it means that it is protected against damage / loss. For example, "My phone is insured against theft". "to ensure" means to make certain of something. "I will ensure that everything is working correctly". "to assure" means to convince someone of something (usually positive). "I assured him that he will pass the test" assure can also be used for the same meaning as ensure.

Alex: Can you [1] ensure (make sure; make certain; see to it) that the travel insurance paperwork is ready before our holiday next week?

Assure is to promise or say with confidence. It is more about saying than doing. Example: I assure you that you’ll be warm enough. Ensure is to do or have what is necessary for success. Example: These blankets ensure that you’ll be warm enough. Insure is to cover with an insurance policy. Example: I will insure my home with additional fire and flood policies. I hope this helps :)
