Korean Honorifics: How 시 and 님 Track Who Outranks Whom
Korean has two separate respect systems. 요/습니다 politeness is about your *listener* — how formally you're speaking to whoever's in front of you. 시 honorifics are about your *subject* — the person the sentence describes, who elevates with 가시다, 읽으세요, 오셨어요 even if they're not in the room. A handful of verbs get replaced outright (드시다, 계시다), and 님 extends the same respect to nouns and names.
Every textbook explains honorifics with some version of "시 shows respect." True, and useless, because 요 also "shows respect," and now you've got two grammar points doing the same job in your head. They're not doing the same job. Politeness and honorifics are two dials wired to two different people in the conversation, and once you see the wiring, half of what looked like exceptions turns out to be one rule, applied consistently.
The two systems everyone conflates
요/습니다 is about your listener. It answers "how formally am I speaking to whoever's in front of me right now?" 시 is about your subject — the person the sentence is actually describing, who might not even be in the room. Ask a friend, in full banmal, where their mom is, and you'll still put 시 on 어머니: 엄마 어디 계셔? The listener gets casual speech. The subject — someone's mother — still gets honored. Two dials, two targets, turning independently.
| Register (listener politeness) | Subject not honored | Subject honored (+시) |
|---|---|---|
| 해체 — banmal | 가 (go) | 가셔 (goes) |
| 해요체 — polite | 가요 (go) | 가세요 (goes) |
| 합쇼체 — formal | 갑니다 (go) | 가십니다 (goes) |
Read down either column and the listener-politeness register climbs. Read across either row and only one thing changes: whether 시 is wedged into the word. That's the entire separation, sitting in six syllables. Miss it, and "honorific" just feels like a vague synonym for "polite" — which is exactly the confusion that makes learners guess instead of reason.
The 시 injection: elevating the person you're talking about
Formation is mechanical. Vowel-ending stems take 시 directly: 가다 (go) → 가시다. Consonant-ending stems get a buffer vowel, 으시: 읽다 (read) → 읽으시다. From there it conjugates like any other verb — 시 just becomes part of the stem, so tense and politeness stack on top of it, not instead of it.
사장님이 먼저 가세요.
sa-jang-ni-mi meon-jeo ga-se-yo.
The boss is heading out first.
가다 → 가시다 + 어요 → 가세요; vowel stem, 시 attaches directly
선생님, 여기 앉으세요.
seon-saeng-nim, yeo-gi an-jeu-se-yo.
Teacher, please sit here.
앉다 → 앉으시다; consonant stem needs the 으 buffer
언제 오셨어요?
eon-je o-syeo-sseo-yo?
When did you arrive?
오다 → 오시다 → 오셨어요: honor (시) goes in before past tense (었)
사장님이 자리에 안 계세요.
sa-jang-ni-mi ja-ri-e an gye-se-yo.
The boss isn't at their desk.
있다 (be, for people) is replaced by 계시다, not 있으시다, when the subject IS the person existing somewhere
That last row is the seam where 시 hands off to a different mechanism entirely — some verbs don't take the 시 suffix at all. They get swapped for a different word.
Special honorific vocabulary: the replacement list
A small set of high-frequency words don't play by the 어간+시 rule — Korean just has a separate, older honorific word for them. You can't guess these; you memorize the list once and reuse it forever, which is a much smaller task than it sounds.
| Plain | Honorific replacement | Example |
|---|---|---|
| 먹다/마시다 (eat/drink) | 드시다 | 진지 드셨어요? — Have you eaten? (진지 is honorific for 'meal' too) |
| 자다 (sleep) | 주무시다 | 안녕히 주무세요 — Good night, said upward to an elder |
| 있다 (be/exist, people only) | 계시다 | 할머니께서 거실에 계세요 — Grandma is in the living room |
| 말/말하다 (words/speak) | 말씀(하시다) | 말씀하세요 — Go ahead, I'm listening |
| 나이 (age) | 연세 | 연세가 어떻게 되세요? — May I ask your age? |
The pattern behind the pattern: these are all words you'd use about someone you're respecting — their eating, sleeping, existing, speaking, aging. That's exactly what 시 elevates for regular verbs, too. It's the same job, just with irregular tools for five extremely common jobs.
님: the same respect, glued onto nouns
님 is 시's cousin for nouns and names — a suffix that says "I'm not going to just say this person's bare title." 선생님 (teacher), 사장님 (boss/owner), 고객님 (customer) — drop the 님 and you're either being rude or talking about a category, not a person. Add a name instead of a title and 님 still works, though it reads more formal than casual Korean usually is: 지훈 씨 is the everyday polite version; 지훈님 shows up in emails, announcements, and — this is the part that ate the internet — online, where nobody knows anyone's age.
That's 님's real 2026 job. On forums, fan cafés, work Slack, and group chats, 님 is the default "you" precisely because Korean politeness normally depends on knowing someone's age and rank, and online you often don't. 님 sidesteps the whole hierarchy problem: safe, flat, works on strangers and celebrities alike.

Yes, Sion-nim is scheduled to attend too.
The mistake that gives away a learner
Honorifics point outward, never at yourself. Learners who've just discovered 시 sometimes sprinkle it everywhere out of general politeness — 제가 회의에 가세요 ("I'll go-honored to the meeting") — which lands somewhere between confusing and comically self-important. You honor the people you're describing; you never honor yourself. If the subject is 저 (I, humble), the verb stays plain: 저는 회의에 가요.
This is also the layer where banmal and jondaetmal start interacting with honorifics in real conversations — the listener-politeness dial and the subject-honorific dial run at the same time, and Korean speakers are constantly reading both before they open their mouth.
Frequently asked questions
What's the actual difference between Korean honorifics and politeness?
Politeness (요, 습니다) is about your listener — how formally you're speaking to whoever you're talking to right now. Honorifics (시, 님, and replacement words like 드시다) are about your subject — the person the sentence describes, who can be honored even if they're not part of the conversation at all.
Do I still honor my own parents when talking to a stranger?
Yes — modern Korean generally keeps family honorifics even toward outsiders: 어머니께서 오셨어요 works whether you're talking to a friend or a stranger. Older workplace rules that lowered honorifics for your own team when speaking to someone even higher up (압존법) have mostly fallen out of everyday use; consistent honorifics are the safer, more current default.
Is 님 always sincerely polite, or can it be used sarcastically?
Default use is neutral-polite — the safe option for strangers, customers, and online strangers of unknown age. Among close friends it can flip playful or mocking (지훈님, 조용히 좀 해주시죠) precisely because it's overly formal for people who normally use banmal — the mismatch is the joke.
Can I get away with skipping honorifics as a beginner?
For a while, yes — Koreans generally forgive learners who default to plain polite speech (해요체) without 시. But you'll hear honorifics constantly in service Korean, dramas, and around elders, so recognizing 드세요, 계세요, and 선생님-style 님 early pays off long before you can produce them fluently yourself.
Why does 계세요 sometimes sound like a question and sometimes like 'goodbye'?
Same honorific word, different context. 할머니 계세요? asks whether grandma is home. 안녕히 계세요 is said to someone who's staying behind when you leave — literally wishing them well as they 'remain.' The verb doesn't change meaning; the situation tells you which job it's doing.
