How can you assure yourself that you can work to ensure your English commitments are met?


A very common confusion amongst my students is the difference between ASSURE and ENSURE. Let's go down the rabbit hole and clarify the exact difference and how to use them correctly.

Firstly: The definitions:

Given the fact that English is one of the languages with the widest range of vocabulary, it has a huge amount of words that, when translated from other languages, have similar meanings but different language uses. When studying English, it is important to understand the key differences between similar sounding words in order to use them correctly.


Ensure and assure are 2 verbs with the same root but different prefixes, which have related meanings in other languages. Understanding their differences will help you determine which one to use depending on the context.


Differences between ENSURE and ASSURE.


ENSURE (verb): to make something certain, to make certain of something/guarantee something is done.


I ensured that we wouldn't run out of paper for the printer by ordering twice as much as last time.

How can we ensure that the construction noise won't disturb our employees?



ASSURE + SOMEONE (verb): to tell someone in a firm way or promise someone that something will happen or that something is certain and remove their doubts or fears.
