There are several words in the English dictionary that often confuse even native English speakers in terms of their usage. One such pair is “assure” and “ensure”.

Although both the words have been derived from the Latin word “securus” which means “safe,” both cannot be used in the same context or in place of each other.

The basic meaning of “assure” is to inform a person confidently about something that is indeed true, in order to prevent the person from worrying about it.

For example, “The CEO assured his employees that their jobs are secure.” It will not be wrong to say that assure is used when you wish to make a kind of promise to another person with regards to something in order to help the other person overcome doubts or anxiety.

On the other hand, ensure means to make sure something will happen.
