Mastering Korean verb conjugation is one of the most essential steps in becoming fluent in Korean. Unlike English, where verbs don’t change much, Korean verbs can take on different forms depending on the subject, tense, level of politeness, and more. In this post, we’ll explore the basics of Korean verb conjugation and provide tips on how to master this important aspect of the language.
1. Understanding Korean Verb Stems
Before we dive into conjugation, it’s important to understand verb stems. In Korean, verbs end in either -다 or -하다, and the root part of the verb is what you modify to conjugate. The verb stem is the part that remains after removing -다.
Example:
- 하다 (hada) → 하 (ha)
- 먹다 (meokda) → 먹 (meok)
2. The Three Tenses: Present, Past, and Future
Korean verbs change according to the tense. Understanding how to conjugate verbs in different tenses is key to mastering verb conjugation.
- Present Tense:
- Regular verbs: Add -아요/어요 to the stem (depending on the vowel).
- 먹다 (meokda) → 먹어요 (meogeoyo) = “I eat.”
- Future Tense:
- Add -겠어요 to the stem.
- 먹다 (meokda) → 먹겠어요 (meokgesseoyo) = “I will eat.”
- Past Tense:
- Add -았/었어요 to the stem.
- 먹다 (meokda) → 먹었어요 (meogeosseoyo) = “I ate.”
- Regular verbs: Add -아요/어요 to the stem (depending on the vowel).

3. Polite and Formal Conjugations
Korean uses honorifics to show respect, and conjugating verbs correctly according to the level of politeness is crucial. There are different forms of politeness, but for most beginners, focusing on -요 (polite form) and -습니다/ㅂ니다 (formal form) will be enough.
Example:
- Casual: 먹어 (meogeo) = “Eat”
- Polite: 먹어요 (meogeoyo) = “Please eat”
- Formal: 먹습니다 (meogseumnida) = “I eat” (used in formal settings)
4. Negative Forms of Verbs
To make a verb negative, you add -지 않다 to the verb stem.
- Present Negative: 먹지 않아요 (meokji anayo) = “I don’t eat.”
- Past Negative: 먹지 않았어요 (meokji anasseoyo) = “I didn’t eat.”
5. Conjugating with Various Verb Endings
Korean verbs also conjugate with different endings based on context. For example:
- -고 싶다 (want to do)
- 먹고 싶어요 (meokgo sipeoyo) = “I want to eat.”
- -지 않다 (negative form)
- 먹지 않아요 (meokji anayo) = “I don’t eat.”
6. Practice, Practice, Practice!
The key to mastering verb conjugation is consistent practice. Start by learning common verbs and conjugating them in different tenses and levels of politeness. Use resources like language apps, textbooks, or speaking with native speakers to reinforce your learning.
Example Verbs to Practice:
- 가다 (gada) – to go
- 하다 (hada) – to do
- 오다 (oda) – to come
- 보다 (boda) – to see
- 자다 (jada) – to sleep
7. Conclusion: Stay Consistent and Keep Learning
