27 Commonly Confused Words in English

The English language has numerous quirks due to regional variations, contributions from other languages, and evolution over time. One of these quirks is that tons of English words sound alike or are spelled differently by one letter, leading to a long list of words often confused by both native and ESL speakers.

Let’s glance through a short selection of the most commonly confused words and their meanings and try to clear up some of the confusion.

The new meaning combines the two words’ definitions into one: amused by something that’s confusing.

Thanks, Autocorrect

Sometimes we write something only to go back later and realize we used the wrong word. In some cases, we find that we use the same misused words every time!

A variety of scientific studies have found that between the late 1980s and about 2010, using the wrong word became a much more common writing error. This time frame coincides with the rise of writing technology like autocorrection and predictive typing. As a result, scientists suspect that we rely on technology to spell words correctly, leading to these errors.

Here are just a few examples of words we often use incorrectly when typing because we expect technology to correct them for us.

Conscious vs. conscience

conscious (adj) = aware
conscience (n) = inner voice or sense of right and wrong
When my conscience is speaking to me, I’m always conscious of it.

Definitely vs. defiantly

definitely (adv) = for sure
defiantly (adv) = in rebellion

Deprecate vs. depreciate

deprecate (v) = to talk negatively about
depreciate (v) = to lose value or lower the value of

Image vs. imagine

image (n) = a picture
imagine (v) = to see a picture or idea in one’s mind

A Better Grammar Checker

Despite finding that we make more errors involving confusing words, scientists have found that we’re not making more errors than ever before—just different kinds of errors. Overall, our spelling has improved, and that’s a fundamental truth. So the solution is not to ditch technology. It’s to develop better technology.

That’s what we’re doing at QuillBot. Our Grammar Checker, Spell Checker and Proofreader are driven by AI, meaning they learn by reviewing thousands upon thousands of high-quality English texts. Using what they learns, they offer you more accurate and helpful suggestions than the standard autocorrection or intelligent typing tools can.
