The most reassuring discovery English speakers make about Korean honorifics is that they are compositional — they are built from small, reusable pieces that snap together predictably, not memorized whole. This page assembles two such pieces. First, the suffix 님 turns a bare role or title into a respectful noun. Second, the honorific subject particle 께서 combines with the topic particle 는 to give 께서는, the honorific version of 은/는. Put them together and you can say 선생님께서는… — "as for the teacher…" — with the topic-vs-subject contrast preserved intact at the honorific tier.
Building block 1: 님 makes a role into a respectful noun
Many Korean nouns for people are bare roles: 선생 ("teacher"), 사장 ("company president"), 교수 ("professor"). On their own they are not how you address or refer to such a person respectfully. Add 님 and the word becomes honorific — and only then does it comfortably take honorific marking like 께서.
| Bare role |
|
|
|---|---|---|
| 선생 (teacher) | 선생님 | 선생님께서 |
| 사장 (company head) | 사장님 | 사장님께서 |
| 교수 (professor) | 교수님 | 교수님께서 |
| 부장 (department head) | 부장님 | 부장님께서 |
사장님께서 회의를 시작하셨어요.

교수님께서 논문을 읽으세요.
gyosunimkkeseo nonmuneul ilgeuseyo
The professor is reading the paper (article).
Skipping 님 makes the respect collapse: to write ✗선생께서 is odd, because 선생 without 님 is not honorific enough to carry 께서. The suffix and the particle sit at the same register, and they belong together.
씨 vs 님 vs 선생님 — a quick orientation
님 is the strong, high-respect suffix. It is worth placing next to its weaker cousin 씨 and the catch-all 선생님, because learners mix them up:
- 씨 attaches to a name (full name 김민수 씨, or given name 민수 씨) and is politely neutral — good for colleagues and acquaintances of roughly your own standing. Do not attach it to a bare surname (✗김 씨 sounds dismissive), and it is not respectful enough for a clear senior.
- 님 attaches to titles and roles (사장님, 부장님, 고객님 "valued customer") and conveys real deference. In online and service contexts it now attaches to names too (민수님).
- 선생님 literally means "teacher," but functions as an all-purpose respectful term for an adult whose title you don't know.
민수 씨, 이거 확인해 주세요.
Min-su ssi, igeo hwaginhae juseyo
Min-su, please check this. (name + ssi — polite, peer-level)
고객님, 잠시만 기다려 주세요.
gogaengnim, jamsiman gidaryeo juseyo
Please wait a moment, ma'am/sir. (title + nim — service deference)
This is only an orientation; the full treatment of address terms — including kinship and fictive-kin terms like 이모, 언니, 오빠, and name + 아/야 — lives on 씨 · 님 · 선생님 and titles & kinship address.
Building block 2: 께서 + 는 = 께서는, the honorific topic
In the plain system you already distinguish the subject particle 이/가 from the topic particle 은/는. The honorific system preserves that very contrast — it just uses honorific parts. The honorific subject is 께서; to make the honorific topic, you attach the topic particle 는 directly onto 께서, giving 께서는.
| Function | Plain particle | Honorific particle |
|---|---|---|
| subject | 이 / 가 | 께서 |
| topic | 은 / 는 | 께서는 |
| also (too) | 도 | 께서도 |
| only | 만 | 께서만 |
The logic is pure addition: 께서 (honorific subject) + 는/도/만 (the particle you want) = the honorific version of that particle. Nothing new to memorize — you already know 는, 도, 만.
아버지께서는 회사에 다니세요.

Only the boss knows.
The topic-vs-subject contrast survives at the honorific tier
Because 께서는 is a real topic marker, it does the same discourse work 은/는 does: it sets up a theme and licenses contrast. Watch two honored subjects play off each other — each takes 께서는, and the sentence reads as a balanced comparison, just as 은/는 would in plain speech.
아버지께서는 신문을 보시고, 어머니께서는 책을 읽으세요.
abeojikkeseoneun sinmuneul bosigo, eomeonikkeseoneun chaegeul ilgeuseyo
My father reads the newspaper, and my mother reads a book. (contrastive topics)
And the subject-vs-topic nuance is preserved too. Use bare 께서 to present new information or answer "who?"; use 께서는 to mark an already-established theme or draw a contrast — the same division of labor as 이/가 vs 은/는.
선생님께서 오셨어요.

Common Mistakes
1. Reversing the order — putting the topic particle before 께서. The case particle 께서 comes first; the topic 는 attaches after it.
❌ 아버지는께서 회사에 다니세요.
Wrong order — 께서 comes first, then 는. It's 아버지께서는.
✅ 아버지께서는 회사에 다니세요.
abeojikkeseoneun hoesa-e daniseyo
As for my father, he works at a company.
2. Using 은 instead of 는 after 께서. 께서 ends in the vowel 어, so the topic particle is 는, never 은.
❌ 아버지께서은 시골에 사세요.
Wrong — after the vowel of 께서 the topic particle is 는, not 은: 아버지께서는.
✅ 아버지께서는 시골에 사세요.

3. Double-marking the topic. 께서는 already contains the topic 는; don't add another 은/는.
❌ 할머니께서는은 편찮으세요.
Wrong — 께서는 already has the topic particle. Don't stack another: 할머니께서는 편찮으세요.
✅ 할머니께서는 편찮으세요.
halmeonikkeseoneun pyeonchaneuseyo
Grandma is unwell. (honorific of 아프다)
4. Marking an honored subject but leaving the verb plain. Like 께서, the honorific topic 께서는 needs -(으)시- on the verb.
❌ 아버지께서는 회사에 다녀요.
Mismatch — 께서는 raises the subject but 다녀요 stayed plain. Add -(으)시-: 아버지께서는 회사에 다니세요.
✅ 아버지께서는 회사에 다니세요.

My father works at a company.
5. Adding 님 to your own parent, or to a name it doesn't fit. 님 attaches to titles/roles (선생님, 사장님); your own father in reference is 아버지, and its honorific is 아버님 — not ✗아버지님.
❌ 우리 아버지님께서 오셨어요.
Wrong — there is no 아버지님. The honorific of 아버지 is 아버님: 우리 아버님께서 오셨어요 (or simply 아버지께서).
✅ 우리 아버지께서 오셨어요.

Key Takeaways
- 님 turns a bare role/title into a respectful noun (선생 → 선생님, 사장 → 사장님) that can then take honorific marking; ✗선생께서 without 님 is off-register.
- Honorific marking is compositional: 께서 (honorific 이/가) + 는 = 께서는 (honorific 은/는); likewise 께서도 ("also"), 께서만 ("only").
- The subject-vs-topic contrast survives: 께서 presents new info; 께서는 marks a theme and licenses contrast.
- Order is fixed — case particle 께서 first, then topic 는 (께서는, never ✗는께서); and don't double-mark (✗께서는은).
- 씨 (peer, on names) < 님 (deference, on titles) — and there is no ✗아버지님; the honorific of 아버지 is 아버님.
