Korean Honorifics Explained: Speech Levels, Suffixes, and Titles
Korean honorifics are less a grammar rule and more a social reflex. You're reading the room — who's older, who's your boss, who's a stranger — and adjusting your verbs. Here's the practical version, starting with one sentence that shows every layer at once.

Korean honorifics are less a grammar rule and more a social reflex. You're reading the room — who's older, who's your boss, who's a stranger — and adjusting your verbs. Here's the practical version, starting with one sentence that shows every layer at once.
Let me start with one sentence, and I'll unpack it backward.
선생님께서 점심을 드세요.seonsaengnimkkeseo jeomsimeul deuseyo.
That's "The teacher is having lunch." And it has three honorific layers stacked into it — the title 선생님, the subject-marking particle 께서 (a respectful version of 이/가), and the verb 드세요 (the honorific form of "eat"). Three choices, one sentence. If I said the same thing to a friend about my brother, it'd be 형이 점심 먹어.hyeoi jeomsim meogeo. Same meaning, zero honorifics.
That's really what this is. Korean honorifics aren't one "feature" — they're a set of small decisions you make in every sentence based on who you're talking to and who you're talking about. Once you see it that way, the system stops feeling like grammar and starts feeling like social awareness.
I started learning honorifics by getting them wrong in front of my Korean teacher in Busan, 2021. I kept using polite-but-not-honorific verbs about her. It's not rude exactly — just tone-deaf, like calling your CEO by their first name at a formal meeting. She was patient. I was embarrassed. That's when I started thinking of honorifics less as rules and more as tuning forks.
Layer 1 — the speech level you end the sentence with
The easy layer. Korean verbs change ending based on who you're speaking to.
- 하십시오-체 — very formal. News anchors, announcements, military.
- 해요-체 — polite everyday. Strangers, coworkers, anyone you don't know well.
- 해-체 (반말) — casual. Friends, younger siblings, kids.
"I'm going" in each:
갑니다.gapnida. — very formal가요.gayo. — polite, your default가.ga. — casual
For everyday life as a foreigner, you want 해요-체 as your baseline. You'll use it with strangers, servers, cab drivers, coworkers you don't know yet. Switching to casual with someone you just met is the single fastest way to be perceived as rude. The rule I give friends: stay polite until the other person invites you to drop down. That's a real Korean ritual — there's even a phrase for it, 말 놓으세요mal noheuseyo ("you can speak casually to me").
Layer 2 — the honorific infix -(으)시- for elevated subjects
This is the layer most learners miss.
When the PERSON YOU'RE TALKING ABOUT — not the person you're talking to — deserves respect, you bump their verb up with -(으)시-.
가다gada →가시다gasida — to go (honorific)먹다meokda →드시다deusida — to eat (a special honorific form)자다jada →주무시다jumusida — to sleep (another special form)
So if I'm telling my friend that my boss is going on vacation, the verb for my boss is honorific even though I'm speaking casually to my friend.
사장님이 휴가 가세요.sajangnimi hyuga gaseyo. — "The 사장님 (sajangnim), the boss, is going on vacation."
The "about whom" is the boss. The "to whom" is my friend. Two different people, two different adjustments.
Beginners mix up these two layers constantly. I did. You'll say 가요gayo when you mean 가세요gaseyo and it won't sound wrong to your ear, but a Korean listener will hear the missing respect immediately. The fix takes a few months of listening — once you tune in, you'll start hearing -세요-seyo, -시--si-, 드세요deuseyo, 주무세요jumuseyo everywhere.
Layer 3 — titles, not names
Koreans do not use first names casually. This is maybe the biggest cultural adjustment in the whole system.
Instead, you use the person's role plus -님 (-nim):
- 선생님 (seonsaengnim) — teacher, or Mr./Ms. as a polite default for any older professional
- 사장님 (sajangnim) — boss, president of a company, or shop owner
- 과장님 — manager (section chief)
- 교수님 — professor
- 기사님 — driver / technician (you'll use this for taxi drivers)
Family is its own system based on the speaker's gender:
- 형 (hyeong) — older brother, male speaker
- 누나 — older sister, male speaker
- 오빠 — older brother, female speaker
- 언니 — older sister, female speaker
And the big one: these extend beyond actual family. A guy's slightly older male friend is his 형. His older female friend is his 누나. This might be the piece of Korean culture that takes foreigners the longest to feel natural with — calling a guy you met at work "older brother."
Unpacking that opening sentence
Back to 선생님께서 점심을 드세요.seonsaengnimkkeseo jeomsimeul deuseyo.
Four honorific moves in seven syllables:
- 선생님 — title (not the teacher's name)
- -님 — suffix of respect on the title
- 께서 — honorific subject particle (replacing 이/가)
- 드세요 — honorific verb for "eat" plus the polite sentence ending
Say the same thing about my younger brother to a friend: 동생이 점심 먹어.dongsaei jeomsim meogeo. No title. No infix. Casual ending. Different universe.
The words for the system itself
When Koreans talk about this system, they use these three words:
- 존댓말 (jondaetmal) — honorific speech in general
- 반말 (banmal) — flat / casual speech
- 높임말 (nopimmal) — "raised" language, same idea as 존댓말
If someone says 반말 해도 돼요?banmal haedo dwaeyo? — "Is it okay if I speak casually?" — they're asking permission to drop honorifics. That's the green light to do the same back.
FAQ
Do Koreans judge foreigners for honorific mistakes?
Almost never for missing a -시--si-. They'll notice, but they'll also know you're learning. The thing to avoid is calling someone by their first name without permission — that's where it stings.
When can I use 반말 with someone? When they invite you, or when you're clearly, unambiguously older (10+ years) and they're a child or a very close junior. When in doubt, stay polite.
Is -세요 the same as -(으)시-?
Closely related. -세요-seyo is the polite-ending version of the honorific. -(으)시--(eu)si- is the honorific infix itself. You'll almost always see them fused together in speech.
Why do Koreans call servers by titles?
사장님sajangnim, 이모imo, 여기요yeogiyo — these are respectful fills for "excuse me." Using a title even for a stranger is the baseline level of politeness.
