When speaking Korean, knowing the appropriate times to use casual (반말) versus formal (존댓말) language is important to avoid sounding rude. Here are some tips to ensure you don’t accidentally sound rude when speaking Korean:
💬 1. Add “-요” or “-예요” to retain respect
When you speak to someone older or someone you’ve just met, end your sentence politely.
If you have a coffee and someone asks you, “What are you drinking?”, responding simply with “커피” is so blunt that it sounds abrasive and rude.
❌ “커피.” - sounds too blunt
✅ “커피요.” or “커피예요.” - polite and friendly
Even short answers should end politely.

🙋♀️ 2. Don’t Just Say “You”
Korean hierarchy is deeply ingrained in the culture and language. Something as simple as saying “you” can come across as rude and uneducated if you use the wrong term.
Words like 너, 당신, or 그대 exist in Korean, but if you do not know the correct settings in which to use these, it can be quite rude.
Instead, try this safer option:
👉 Use the person’s name + 씨 (e.g., 민수씨)
👉 Or their title (e.g., 선생님, 팀장님)


For more details on the different words for “you,” we have more extensive descriptions in other lessons available on our YouTube channel.
To Sum Up
It is important to become familiar with how to interact with others when speaking Korean to avoid sounding rude.
For our first tip, remember to end your sentence with “-요” or “-예요”.
Finally, become familiar with the different forms of “you,” or when in doubt, rely on honorifics.
