Korean Verb/Adjective Conjugator

Q: What is the ㅂ irregular and how do I recognize it?

When a stem ends in the batchim ㅂ, that ㅂ often changes to 오/우 before a vowel-starting ending. Examples: 춥다 becomes 추워요 (cold), 어렵다 becomes 어려워요 (difficult). Some ㅂ-ending verbs are actually regular, such as 입다 (to wear) becoming 입어요, so each verb needs to be checked individually.

What Is Korean Verb Conjugation?

Korean verbs and adjectives change their endings depending on tense, speech level (how polite you're being), and sentence type — not on the subject's person or number, the way English verbs do. The Korean Verb Conjugator tool above lets you type any dictionary-form verb (e.g. 가다 "to go", 먹다 "to eat", 아프다 "to be sick") and instantly see its full conjugation table: present, past, and future tense, across statements, questions, commands, suggestions, connectives, and noun forms — from casual speech to the most formal register.

Stem and Ending

Every conjugation starts by removing -다 from the dictionary form to get the stem. For example, 가다 → stem 가, and 먹다 → stem 먹. What you attach to that stem determines the speech level and tense:

Speech Level	Present Tense Example (가다 / 먹다)
Informal low (반말)	가 / 먹어
Informal high (해요체)	가요 / 먹어요
Formal low (해라체)	간다 / 먹는다
Formal high (합니다체)	갑니다 / 먹습니다

Frequently Asked Questions

How do verbs ending in 하다 conjugate?

Verbs ending in 하다 replace the whole 하 syllable with 해. For example: 일하다 → 일해요 (to work), 공부하다 → 공부해요 (to study), 사랑하다 → 사랑해요 (to love). Across speech levels this stays regular: informal high is 해요, formal high is 합니다.

What is the ㅂ irregular and how do I recognize it?

When a stem ends in the batchim (final consonant) ㅂ, that ㅂ often changes to 오/우 before a vowel-starting ending. Examples: 춥다 → 추워요 (cold), 어렵다 → 어려워요 (difficult). Note some ㅂ-ending verbs are actually regular (e.g. 입다 "to wear" → 입어요), so it's worth checking each verb individually — the conjugator above does this automatically.

What's the difference between informal (반말) and polite (해요체) speech?

Informal speech (반말) is used with close friends or people younger than you; 해요체 is the everyday polite form used with strangers, coworkers, or in most day-to-day polite conversation. The most common difference is simply whether -요 is attached: 가 (informal) → 가요 (polite).

How do I form the past tense in Korean?

Start from the 아/어 form, then contract in 았/었 with a final ㅆ batchim. For example: 가다 → 가 + 았 → 갔어요 (went), 먹다 → 먹어 + 었 → 먹었어요 (ate).
