불규칙 활용The ten irregular classes
Every irregular Korean verb belongs to one of these, and each class is one rule applied to a whole list of words.

표 보는 법How to read the tables
Every verb page carries these same groups in this same order, so once this is clear it is clear everywhere.
- 현재Present
- The tense that does the most work. 해요체 is the one to learn first — it is polite without being formal, and it is what most conversation is in.
- 과거Past
- Built from the 아/어 form plus ㅆ, which is why an irregular stem's irregularity shows up here and nowhere else in the past tense.
- 미래·추측Future & presumptive
- -겠- is as much a guess as a future: 맛있겠다 means "that must be delicious". For a plan, -을 거예요 is the everyday form.
- 의문Questions
- 해요체 and 해체 mark a question with intonation alone — the form is identical to the statement, and only the question mark and your voice differ.
- 명령Commands
- Korean has no neutral imperative. Every one of these carries a speech level, and 하세요 — grammatically an honorific — is the everyday polite one.
- 부정Negation
- Two negations, and they are not interchangeable in register: 안 is short and spoken, -지 않다 is longer and written. 못 negates ability rather than intention.
- 높임Honorific
- -으시- honours the person doing the action, not the listener, so you use it about your boss and never about yourself.
- 관형사형Modifying a noun
- Korean's relative clause. The whole clause goes in front of the noun, and the tense is carried by this ending rather than by a separate verb.
- 연결Joining clauses
- Korean joins clauses by inflecting the first verb rather than by putting a word between them, which is why these are endings and not conjunctions.
- 진행In progress
- -고 있다 is the true progressive. The plain present covers habitual action, so 먹어요 alone can mean either "I eat" or "I'm eating".

자주 묻는 질문Common questions
How many irregular verbs does Korean have?
Ten classes, and 1,133 of the 3,698 verbs and adjectives here belong to one. That sounds worse than it is: 697 of them are 하다 verbs, which are all one paradigm repeated, and the genuinely awkward classes — ㅂ, 르, ㄷ, ㅅ — come to a few hundred words between them.
What are the four Korean speech levels?
해요체 is the everyday polite form and the one to learn first. 합니다체 is formal — announcements, presentations, the news. 해체 is 반말, used with friends and people younger than you. 한다체 is the plain written style you meet in books and newspapers. Every table here shows all four side by side, because choosing between them is the actual skill.
Do Korean adjectives conjugate?
Yes. 형용사 are stative verbs — 춥다 is closer to "to be cold" than to "cold" — so they take tense and speech-level endings exactly as action verbs do and need no copula. What they do not have is an imperative or a propositive: you cannot order someone to be cold, and the tables here leave those rows out for adjectives.
Are these tables generated or hand-written?
Generated, from the dictionary form, the part of speech and the irregular class — Korean conjugation is fully algorithmic given those three. The engine is checked on every build against the 9,380 conjugated forms the 국립국어원 dictionary itself publishes, and reproduces 99.8% of them; the remainder are archaic speech levels and a handful of dictionary typos.
