Commonly Confused Words

Do you often pause mid-sentence to wonder if the word you want to use is affect or effect? Are you unsure of the difference between the verbs see, watch, and look? Do you regularly find yourself typing out there in a text message or in an email only to realize too late that it should have been their? If any of these concerns sound familiar to you, you’re certainly not alone. Even fluent English speakers are often confused about the same words!

Here is a list of some commonly confused words and how to differentiate between them
