Ensure vs. insure is confusing because both words relate to making something certain or protected. They often appear in similar contexts, especially in formal writing, which makes it easy to mix them up.
The difference comes down to purpose. One word is used when you want to make sure something happens. The other is used when you are protecting something financially, usually through insurance.
