Understanding the Basics of Korean Verb Conjugation

Before diving into the past tense in Korean, it is crucial to understand how Korean verbs function. Korean verbs are conjugated based on tense, mood, politeness level, and formality. Unlike English, Korean verbs do not change according to the subject’s person or number, which simplifies some aspects of conjugation.

Verb Stem and Endings

Every Korean verb consists of a stem plus endings that indicate tense, mood, or politeness:

– **Verb stem**: The base form obtained by removing 다 (da) from the dictionary form of the verb.
– **Endings**: Added to the stem to indicate tense (past, present, future), mood (declarative, interrogative), and politeness.

Example:
– 가다 (gada) – to go
– Stem: 가 (ga)
– Present tense polite ending: -요 (yo)
– Past tense polite ending: -았어요 or -었어요 (depending on the verb stem vowel)

Forming the Past Tense in Korean

The past tense in Korean is primarily formed by adding specific past tense endings to the verb stem. The most common endings are **-았어요**, **-었어요**, and **-였어요**, which correspond roughly to the English “-ed” or “did” for regular verbs.

How to Choose the Correct Past Tense Ending

The choice between -았어요, -었어요, and -였어요 depends on the vowel of the verb stem:

– Use **-았어요** if the last vowel in the stem is ㅏ (a) or ㅗ (o).
– Use **-었어요** if the last vowel is anything else.
– Use **-였어요** for 하다 (hada) verbs, which are very common and often used to form compound verbs.

Examples:
– 가다 (to go) → 가 + 았어요 = 갔어요 (went)
– 먹다 (to eat) → 먹 + 었어요 = 먹었어요 (ate)
– 공부하다 (to study) → 공부하 + 였어요 = 공부했어요 (studied)

Summary of Past Tense Endings

| Verb Stem Vowel | Past Tense Ending | Example Verb | Past Tense Form | Meaning |
|—————–|——————-|————–|—————–|———|
| ㅏ or ㅗ | -았어요 | 가다 (to go) | 갔어요 | went |
| Others | -었어요 | 먹다 (to eat)| 먹었어요 | ate |
| 하 (하다 verbs) | -였어요 | 공부하다 (to study) | 공부했어요 | studied |

Politeness and Formality in Past Tense Korean

Korean language has various speech levels that affect how verbs are conjugated. The past tense endings can change depending on the level of politeness and formality.

Common Politeness Levels

– **Informal polite** (used with strangers or acquaintances): -았어요 / -었어요 / -였어요
– **Formal polite** (used in formal conversations or with elders): -았습니다 / -었습니다 / -였습니다
– **Informal low** (used with close friends or younger people): -았어 / -었어 / -였어

Examples Across Politeness Levels

| Politeness Level | Verb (가다 – to go) | Past Tense Form | Example Sentence |
|——————|——————–|—————–|————————————-|
| Informal polite | 갔어요 | 갔어요 | 저는 어제 학교에 갔어요. (I went to school yesterday.) |
| Formal polite | 갔습니다 | 갔습니다 | 저는 어제 학교에 갔습니다. (I went to school yesterday.) |
| Informal low | 갔어 | 갔어 | 너 어제 학교에 갔어? (Did you go to school yesterday?) |

Irregular Verbs in the Korean Past Tense

While most Korean verbs follow the regular past tense conjugation rules, some verbs are irregular and undergo changes in their stems when conjugated. Learning these irregularities is important to avoid common mistakes.

Types of Irregular Verbs

– **ㅂ-irregular verbs**: When followed by a vowel, the ㅂ changes to 우 or 오.
– Example: 돕다 (to help) → 도왔어요 (helped)
– **ㄷ-irregular verbs**: ㄷ changes to ㄹ before a vowel.
– Example: 듣다 (to listen) → 들었어요 (listened)
– **르-irregular verbs**: Add an extra ㄹ and change the ending accordingly.
– Example: 모르다 (to not know) → 몰랐어요 (did not know)
– **ㅎ-irregular verbs**: Drop the ㅎ when followed by a vowel.
– Example: 놓다 (to put) → 놓았어요 (put)

Examples of Common Irregular Past Tense Conjugations

| Verb | Stem Change | Past Tense Form | Meaning |
|————|———————|—————–|—————-|
| 돕다 | ㅂ → 우 | 도왔어요 | helped |
| 듣다 | ㄷ → ㄹ | 들었어요 | listened |
| 모르다 | 르 → ㄹ + ㄹ | 몰랐어요 | did not know |
| 놓다 | ㅎ dropped | 놓았어요 | put |

Using the Past Tense in Korean Sentences

Once you understand how to form the past tense, it’s essential to practice constructing full sentences. The past tense can be used in various sentence types: declarative, interrogative, and negative.

Declarative Sentences

These sentences simply state a fact about the past.

– 저는 어제 영화를 봤어요.
(I watched a movie yesterday.)
– 친구가 한국에 갔어요.
(My friend went to Korea.)

Interrogative Sentences

These ask a question about past actions.

– 어제 뭐 했어요?
(What did you do yesterday?)
– 그 사람을 만났어요?
(Did you meet that person?)

Negative Sentences

To negate past tense, use **안** before the verb or conjugate the verb into the negative past tense form.

– 저는 어제 숙제를 안 했어요.
(I did not do homework yesterday.)
– 음식을 먹지 않았어요.
(I did not eat food.)
