45 Cool English Words You Need to Know

Of the thousands and thousands of existing English words, there are some cool words that have such a unique sound or meaning that you’ve just got to learn them. Including these cool-sounding words in your communication adds depth to your descriptions and makes your language more interesting. And they can break up the repetitiveness of always using the same words.

If you’re still a beginning English learner, you’ll probably want to stick to the most common words in English. You’ve likely heard many of these two or three thousand common words in everyday conversation. But if you’re further along your journey, you can start adding some more unique words to your vocabulary.

A word of warning, though. When it comes to unique words, less is more. Don’t use them too much, or your meaning will become unclear, and people might think you’re a show-off.

In this article, you'll discover 45 cool English words you might not have seen or heard before.

Cool words to impress your friends and engage your audience

Be careful not to overuse them, though. These aren’t super common words. You can sprinkle them in when it feels right to add uniqueness to your English. The important word here is ‘sprinkle.’ Less is more with these words. Your goal when communicating is to always be clear and easy to understand.

Use these words rarely but in the right places, and you’ll interest and engage your audience. Use them too much, and you’ll have the opposite effect. People will switch off, thinking you're showing off your vocabulary knowledge.

In short, prioritize speaking clearly over everything else (even sounding cool). But above all else, keep learning more vocabulary, and your English skills will continue to improve!
