Understanding the past tense in Korean grammar can be a challenging but rewarding endeavor for language learners. Unlike English, Korean employs a different set of rules and nuances to convey actions that have occurred in the past. This article aims to demystify the past tense in Korean, providing you with a solid foundation to understand and use it correctly.
The Basics of Korean Verbs
Before diving into the past tense, it’s essential to understand how Korean verbs function in general. Korean verbs consist of a verb stem and various endings that indicate tense, politeness level, and mood. The verb stem is the core meaning of the verb, while the endings modify this meaning to give additional context.
For instance, the verb “to eat” is 먹다 (meokda). Here, 먹 (meok) is the verb stem, and 다 (da) is the infinitive ending. To use this verb in different tenses, you’ll modify the ending.
Forming the Past Tense
Forming the past tense in Korean involves a few straightforward steps. The general rule is to take the verb stem and add a past tense marker along with a polite or casual ending.
Step-by-Step Guide:
1. **Identify the Verb Stem:**
Remove 다 (da) from the dictionary form of the verb. For example, 먹다 (meokda) becomes 먹 (meok).
2. **Add the Past Tense Marker:**
The past tense marker is 았/었/였 (at/eot/yeot). The choice of marker depends on the vowel in the verb stem:
– If the last vowel of the verb stem is ㅏ (a) or ㅗ (o), use 았 (at).
– If the last vowel is not ㅏ or ㅗ, use 었 (eot).
– For 하다 (hada) verbs, use 였 (yeot).
3. **Attach the Appropriate Ending:**
Depending on the level of politeness you want to convey, you can choose between various endings. For standard polite speech, you would typically use 어요/아요 (eoyo/ayo).
Let’s look at some examples:
– 먹다 (meokda) – to eat
– Verb stem: 먹 (meok)
– Past tense marker: 었 (eot)
– Ending: 어요 (eoyo)
– Past tense form: 먹었어요 (meogeosseoyo) – “ate”
– 가다 (gada) – to go
– Verb stem: 가 (ga)
– Past tense marker: 았 (at)
– Ending: 어요 (eoyo)
– Past tense form: 갔어요 (gasseoyo) – “went”
– 공부하다 (gongbuhada) – to study
– Verb stem: 공부하 (gongbuha)
– Past tense marker: 였 (yeot)
– Ending: 어요 (eoyo)
– Past tense form: 공부했어요 (gongbuhaesseoyo) – “studied”
Politeness Levels
Korean is a language rich in politeness levels, and the way you conjugate verbs can change based on the formality of the situation. Here’s how to form the past tense in different levels of politeness:

– 가다 (gada) – 갔어 (gasseo)
Informal High (해요체):
– 먹다 (meokda) – 먹었어요 (meogeosseoyo)
– 가다 (gada) – 갔어요 (gasseoyo)
Formal (하십시오체):
– 먹다 (meokda) – 먹었습니다 (meogeosseumnida)
– 가다 (gada) – 갔습니다 (gasseumnida)
Irregular Verbs
While many Korean verbs follow the regular pattern for forming the past tense, some verbs are irregular. Here are a few common irregular verbs and how they change in the past tense:
ㅂ Irregular Verbs:
– 돕다 (dobda) – to help

2. Incorrect Politeness Levels:
