A form like 읽으시겠어요 looks intimidating until you realize it is not one thing to memorize but four small things clicked together in a fixed order. Korean is an agglutinating language: it builds a predicate by stacking meaning-slots onto the stem, each in its own reserved position. Once you know the slot order, you can assemble — and disassemble — honorific verbs of any length without guessing. This page gives you that order.
The slot template
Every finite Korean verb follows the same left-to-right sequence:
STEM + (으)시 + 었/겠 + final ending
| Slot | Carries | Examples |
|---|---|---|
| the lexical meaning | 읽-, 가-, 오- |
| subject honorific (respect) | 읽으시-, 가시- |
| tense / modality (time, conjecture, intention) | 읽으셨-, 가시겠- |
| speech level (who you address) | -어요, -습니다, -어 |
The meanings run in a logical cascade: respect → time → attitude → addressee. Read left to right, 오셨겠어요 decomposes as 오- (come) + 시 (honoring the comer) + 었 (in the past) + 겠 (I conjecture) + 어요 (politely to you) = "(he/she, respected) must have come."
Slot 2 alone: honorific, present
With nothing in the tense slot, you get the plain honorific present.
어디 사세요?
eodi saseyo
Where do you live?
살다 → drops ㄹ before -시- → 사시- → present 사세요. (The -세요 ending is -(으)시- + -어요 contracted; full treatment on the honorific endings page.)
Slots 2 + 3: honorific + past
Feed the honorific stem into the past. Recall that -시었- always contracts to -셨-, so the seam never shows.
어디 사셨어요?
eodi sasyeosseoyo
Where did you (formerly) live?
교수님께서 논문을 발표하셨습니다.
gyosunimkkeseo nonmuneul balpyohasyeotseumnida
The professor presented the paper. (formal)
Slots 2 + 3: honorific + 겠 (conjecture / intention)
The modal -겠- in slot 3 adds conjecture ("must be / probably") or, in questions to the listener, polite intention ("would you…"). Unlike -었-, it does not contract with -시-; the sequence stays -시겠-.
많이 피곤하시겠어요.
mani pigonhasigesseoyo
You must be very tired.
이 기사 읽으시겠어요?
i gisa ilgeusigesseoyo
Would you like to read this article?
All four slots: honorific + past + 겠 + ending
The tense and modal slots can both be filled — -셨겠- — stacking past onto conjecture: "must have (done)."
어제 많이 피곤하셨겠어요.
eoje mani pigonhasyeotgesseoyo
You must have been very tired yesterday.
벌써 도착하셨겠어요.
beolsseo dochakasyeotgesseoyo
They must have already arrived.
A pronunciation reminder that falls straight out of the stacking: the ㅆ of -셨- and the ㅅ of -겠- both neutralize to a [t] sound before a following consonant and do not liaise, so -셨겠어요 reads -syeot-ge-sseoyo (the final 겠 does liaise into the vowel of 어요). This is why the romanization shows -셨습니다 as -syeotseumnida and -셨겠- as -syeotget-, never with a double ss.
The ending slot sets the register
Slots 1–3 are identical across politeness levels; only slot 4 changes. This is the cleanest way to shift register: keep the honorific-tense core and swap the ending.
| Register | Ending | "went (hon.)" |
|---|---|---|
| 합니다체 (formal polite) | -습니다 | 가셨습니다 |
| 해요체 (informal polite) | -어요 | 가셨어요 |
| 한다체 (plain written) | -다 | 가셨다 |
회장님께서 이미 자리를 뜨셨습니다.
hoejangnimkkeseo imi jarireul tteusyeotseumnida
The chairman has already left his seat. (formal)
Honorific vs humble can co-occur
Subject honorific -(으)시- elevates someone else as the subject. The humble benefactive -아/어 드리다 lowers your own action performed toward them. In a single exchange, both directions of the same relationship appear — you raise them with -시-, you lower yourself with 드리다:
제가 도와드릴게요.
jega dowadeurilgeyo
Let me help you. (I lower my own action)
선생님께서 도와주셨어요.
seonsaengnimkkeseo dowajusyeosseoyo
The teacher helped me. (I raise their action with -시-)
These are not contradictory — they are the two halves of Korean's respect system pointing in opposite directions at the same relationship.
How this differs from English
English builds a "complex" verb with separate words in a loose order — "would probably have gone" is four words, and you can even rearrange the adverb ("probably would have gone"). Korean fuses the same meanings into one word with no freedom of order: respect, then tense, then modality, then addressee, locked. That rigidity is actually a gift — because the slots never move, a monster like 오셨겠습니다 is 100% predictable, both to produce and to parse. The trap for English speakers is importing English's flexibility and its instinct to put tense innermost; Korean puts respect innermost (closest to the stem) and addressee outermost (the very last ending).
Common Mistakes
1. Tense before honorific. The archetypal error — past jumps ahead of respect.
❌ 사장님께서 방금 갔으셨어요.
Wrong — tense -았- is before honorific -시-. Rebuild: 가- + 시 + 었 → 가셨어요.
✅ 사장님께서 방금 가셨어요.
sajangnimkkeseo banggeum gasyeosseoyo
The boss just left.
2. Modal before honorific. -겠- must sit in slot 3, after -(으)시-.
❌ 곧 도착하겠으세요.
Wrong — -겠- is before -시-. Correct order is 도착하시겠어요.
✅ 곧 도착하시겠어요.
got dochakasigesseoyo
You'll be arriving soon.
3. Double-marking the honorific. A suppletive stem like 드시- already contains 시; adding another -(으)시- is redundant.
❌ 할아버지께서 진지를 드시으세요.
Wrong — 드시다 already has 시; don't add another. It's simply 드세요.
✅ 할아버지께서 진지를 드세요.
harabeojikkeseo jinjireul deuseyo
Grandfather is eating his meal.
4. Leaving -시었- uncontracted. The contraction to -셨- is obligatory.
❌ 어제 뭐 하시었어요?
Wrong — -시었- must contract to -셨-: 하셨어요.
✅ 어제 뭐 하셨어요?
eoje mwo hasyeosseoyo
What did you do yesterday?
5. Dropping the final ending (slot 4). A verb needs its speech-level cap; a bare -셨- is not a sentence.
❌ 사장님께서 벌써 오셨.
Incomplete — no speech-level ending. Add -어요 or -습니다.
✅ 사장님께서 벌써 오셨어요.

Key Takeaways
- The predicate stacks in a fixed order: STEM + (으)시 + 었/겠 + ending — respect, time, attitude, addressee.
- Honorific always precedes tense. Every ×갔으세요-type error is a slot violation; rebuild from the stem.
- -시었- contracts to -셨- (obligatory); -시겠- stays -시겠-.
- Both tense slots can fill: -셨겠- = "must have (done)."
- Only the final ending changes register (가셨습니다 / 가셨어요 / 가셨다); the core is constant.
- Subject honorific -(으)시- (elevating others) and humble -아/어 드리다 (lowering yourself) can appear side by side.

- Honorific Past -(으)셨-: 가셨어요, 읽으셨습니다TOPIK 2 — The honorific past is not a separate morpheme — it is the honorific stem -(으)시- fed into the ordinary past machinery, where -시었- always contracts to -셨-.
- Subject Honorific -(으)시-: Raising the SubjectTOPIK 1 — -(으)시- is a verbal infix that shows respect toward the grammatical SUBJECT — inserted between stem and ending: 가시다, 읽으시다, 사시다. It honors whoever the sentence is about, never yourself, and is completely independent of the speech level (해요체/합니다체) you address the listener with.
- -아/어 드리다 & -아/어 주시다: The Giving TriadTOPIK 3 — The honorific and humble counterparts of -아/어 주다 — pick the form by mapping the social geometry of a favor: who acts and who benefits.
- -겠-: Intention and ConjectureTOPIK 2 — -겠- is a modal pre-final marker, not a plain future tense: it expresses the speaker's intention/volition (제가 하겠습니다), conjecture about a situation (맛있겠어요, 비가 오겠어요), and survives in frozen phrases (알겠습니다, 모르겠어요) — with the subject largely deciding which reading you get.
- Suppletive Honorific Verbs: 계시다, 드시다, 주무시다, 돌아가시다TOPIK 2 — The small closed set of verbs that don't take -(으)시- but swap to a wholly different honorific stem — Korean's version of go/went, and the ones you simply have to memorize.
