Guaranteed to get it right: Insure vs. ensure

Thanks to insure and ensure being so similar in the way they’re pronounced, they’re often confused. They do share similar word origins, and a few grammar pontiffs say they’re interchangeable. Such an opinion is in the minority, however.

Ensure means to guarantee a situation. For example: By bringing an umbrella, Jane ensured they would not get wet during their walk.

Insure means to limit one’s financial liability. For example: Sophia decided that despite the expense and her limited funds, she needed to insure her car.

Hopefully this entry will ensure you now know how to use insure so that you can garner an income from writing.
