Common Mistakes To Avoid
When it comes to using the words “assure” and “ensure,” people often make the mistake of using them interchangeably, when in fact, they have different meanings and uses. Here are some common mistakes to avoid:
Mistake 1: Using “Assure” When “Ensure” Is The Correct Word
One of the most common mistakes people make is using “assure” when “ensure” is the correct word to use. “Assure” means to promise or guarantee, while “ensure” means to make sure something happens or to guarantee the outcome of something.
For example, if you want to make sure that a package is delivered on time, you would use “ensure,” not “assure.” Saying “I assure you that the package will be delivered on time” implies that you are making a promise or guarantee, which may not be within your control.
Mistake 2: Using “Ensure” When “Insure” Is The Correct Word
Another common mistake is using “ensure” when “insure” is the correct word to use. “Insure” means to protect against loss or damage, usually by purchasing insurance.
For example, if you want to protect your car against theft or damage, you would “insure” it, not “ensure” it. Saying “I will ensure my car against theft” is incorrect, as “ensure” does not have the same meaning as “insure.”
Tips To Avoid These Mistakes
- Double-check the definition of the word before using it to make sure it is the correct one.
- Use a thesaurus to find synonyms for the word you want to use to make sure it has the right meaning.
- Read your writing out loud to make sure it sounds correct and makes sense.

| Logistics | “I can assure you that your package will be delivered on time.” | “We need to ensure that all packages are delivered on time.” |
As you can see from these examples, the choice between “assure” and “ensure” can depend on the specific context in which they are used. In general, “assure” tends to be used more in situations where someone is giving a guarantee or making a promise, while “ensure” is used more in situations where someone is taking action to make sure something happens.
