존댓말 — Korean Formal Speech for Beginners
Korean has two speech levels — formal and informal — and knowing when to use which is one of the most important social skills in the language. Here's the clearest breakdown for beginners.

You meet someone new in Korea.
Are they older than you? Younger? A colleague? A stranger?
In English, you speak to everyone roughly the same way and let your tone do the work.
In Korean, the grammar itself changes.
This is 존댓말 and 반말 — the two speech levels that every Korean speaker navigates constantly. Understanding them is one of the most important steps in learning Korean.
The two words
The key difference: the -요 ending
The most visible difference between 존댓말 and 반말 is the -요 ending.
존댓말: 어디 가요? (Where are you going?)
반말: 어디 가? (Where are you going?)
Same question. Same meaning. Very different social signal.
Core examples
When to use which
존댓말 vs 반말
Two conversations: one with a new colleague, one with a close friend
When to use 존댓말 vs 반말
Switching to 반말
Koreans don't automatically switch to 반말 just because they become friends. There's often an explicit moment: 말 놓을게요 (I'll drop the formal speech) or 말 편하게 해도 돼 (you can speak casually with me).
Waiting for that moment — or asking for it — is the right approach.
Cultural note
The 존댓말 / 반말 system reflects Korea's deeply hierarchical social structure. Age, position, and closeness all determine how you speak to someone. Using 반말 with a stranger or someone older without permission is a genuine social offense.
As a Korean learner, using 존댓말 with everyone is always the safe choice. No one will ever be offended that you were too respectful. And when someone offers you 반말 — when they say you can speak casually — it's a small but real sign of warmth and acceptance.
That invitation matters. Notice it when it comes.
