When it comes to fancy yet useful words, the English language has tons to offer. Here are 25 examples of smart words that you can use in daily conversation. 

As an English learner, one of the best feelings in the world is creating better English sentences. There’s just something very satisfying in knowing some smart words to use in a conversation and using them. We all had that “Yes, I did it!” moment after using something we learned in real life. 

Adding beautiful words in your vocabulary has some benefits as well. Some of the advantages of learning powerful words are improving English pronunciation, better-articulated speeches, and better reading and listening comprehension. Besides, it makes you feel and sound smart, which you can use to your advantage professionally.

Why Sounding Smart Is A Good Thing? 

Did you know that there’s a benefit when you sound fluent like a native speaker? According to a Harvard Business Review study, an applicant’s voice and sound can affect the employer’s impression during interviews. The more confident and smart-sounding your voice is, the better you can fare in job interviews. 

Using big words can be frowned upon and even ridiculed by some English speakers. After all, there are times that these complicated words can be frustrating and irritating to the listener. If misused, they make you sound incoherent instead of smart. Make sure that you understand the word you’re going to use in a sentence. Here are other tips to sound smarter and more confident when speaking in English. 

• Check and fix your posture (stand straight, but remain relaxed)
• Speak loud and clear
• Use matching body language 
• Use appropriate words based on the audience.
• Always practice your English daily.
