Korean Grammar: 문법
Korean grammar is logical and consistent once you learn the core rules. The biggest shift from English is the word order: Korean is SOV (Subject–Object–Verb), meaning the verb always comes at the end. Particles (조사) attach to nouns to show their grammatical role — no need to memorize rigid word positions!
1 Word Order — SOV Structure (어순)
Unlike English (Subject-Verb-Object), Korean follows Subject → Object → Verb order. The verb (동사) always comes at the END of the sentence.
| English (SVO) | Korean (SOV) | Literal Korean |
|---|---|---|
| I eat rice. | 나는 밥을 먹어요. | I (topic) rice (object) eat. |
| She loves Korea. | 그녀는 한국을 사랑해요. | She (topic) Korea (object) loves. |
| They study Korean. | 그들은 한국어를 공부해요. | They (topic) Korean (object) study. |
| I go to Seoul. | 나는 서울에 가요. | I (topic) Seoul (to) go. |
2 Korean Particles (조사)
Particles are suffixes attached to nouns that indicate grammatical function. They are the backbone of Korean sentence structure — once you master particles, grammar becomes much clearer!
| Particle | Function | Rule | Example | Listen |
|---|---|---|---|---|
| 은/는 | Topic marker | 은 after consonant, 는 after vowel | 나는 학생이에요 I am a student (topic) |
|
| 이/가 | Subject marker | 이 after consonant, 가 after vowel | 비가 와요 Rain is coming (rain = subject) |
|
| 을/를 | Object marker | 을 after consonant, 를 after vowel | 밥을 먹어요 I eat rice (rice = object) |
|
| 에 | Location / Direction | Destination or static location | 학교에 가요 I go to school |
|
| 에서 | Location of action | Where an action takes place | 학교에서 공부해요 I study at school |
|
| 의 | Possessive | Like "of" or "'s" | 나의 친구 My friend (friend of me) |
|
| 와/과 | And (with nouns) | 와 after vowel, 과 after consonant | 사과와 바나나 Apple and banana |
|
| 도 | Also / Too | Replaces 은/는 or 이/가 | 저도 좋아요 I like it too |
|
| 만 | Only | Exclusive focus | 물만 마셔요 I only drink water |

3 Verb Conjugation (동사 변화)
Korean verbs always end in 다 (da) in their dictionary form. To use them in sentences, replace 다 and add the appropriate ending based on formality level and tense.
Speech Levels (존댓말 vs 반말)
| Level | When to Use | "To eat" (먹다) | Translation |
|---|---|---|---|
| Formal 격식체 |
Official settings, strangers, broadcast | 먹습니다 | I eat (formal) |
| Polite 존댓말 |
Most daily use, adults, strangers | 먹어요 | I eat (polite) |
| Casual 반말 |
Close friends, younger people, informal | 먹어 | I eat (casual) |
Present Tense (-아요/-어요)
The most common form is the polite present tense. Add -아요 after stems with ㅏ or ㅗ vowels, and -어요 for all other vowels.
| Dictionary Form | Stem | Conjugated | English |
|---|---|---|---|
| 가다 | 가- | 가요 | goes/I go |
| 오다 | 오- | 와요 | comes/I come |
| 먹다 | 먹- | 먹어요 | eats/I eat |
| 마시다 | 마시- | 마셔요 | drinks/I drink |
| 자다 | 자- | 자요 | sleeps/I sleep |
| 공부하다 | 공부하- | 공부해요 | studies/I study |
| 좋아하다 | 좋아하- | 좋아해요 | likes/I like |
| 배우다 | 배우- | 배워요 | learns/I learn |
| 보다 | 보- | 봐요 | sees/I see |
| 하다 | 하- | 해요 | does/I do |
Past Tense (-았어요/-었어요)
Add -았어요 (after ㅏ/ㅗ stems) or -었어요 (all others) to form past tense.
Future Tense (-을 거예요/-ㄹ 거예요)
4 Making Sentences Negative (부정문)
There are two ways to negate in Korean:
| Method | Pattern | Example | Translation |
|---|---|---|---|
| Short negation | 안 + verb | 안 먹어요 | I don't eat |
| Long negation | verb stem + 지 않아요 | 먹지 않아요 | I don't eat |
| Cannot | 못 + verb | 못 먹어요 | I can't eat |
| Is not | noun + 이/가 아니에요 | 학생이 아니에요 | I'm not a student |
5 Forming Questions (의문문)
In Korean, questions are formed simply by changing the intonation (rising) or adding a question mark. The word order does NOT change unlike English!

| ~고 싶어요 | want to ~ | 한국에 가고 싶어요 — I want to go to Korea |
| ~해 주세요 | Please do ~ | 천천히 말해 주세요 — Please speak slowly |
| ~ㄹ/을 수 있어요 | can / be able to | 한국어를 할 수 있어요 — I can speak Korean |

7 Connectors: 그리고, 그래서, 그렇지만, 그런데
Connectors (접속사) are conjunctions placed at the beginning of a new clause or sentence to link ideas together. These four are the most essential for flowing Korean speech.
| Korean | Romanization | Meaning | When to Use |
|---|---|---|---|
| 그리고 | geurigo | And / And then | Adds information; lists items or sequential actions |
| 그래서 | geuraeseo | So / Therefore | Cause → result; the result follows logically |
| 그렇지만 | geureochiman | But / However | Strong contrast; more formal than 그런데 |
| 그런데 | geureonde | But / By the way | Soft contrast or topic shift; very common in conversation |
8 And, With: -하고, -(이)랑
While 그리고 connects sentences, Korean uses specific particles to say "and/with" between nouns. The two most common casual particles are -하고 and -(이)랑.
| Particle | Rule | Register | Example |
|---|---|---|---|
| 하고 | After any noun (no variation) | Neutral / casual | 친구하고 갔어요 Went with a friend |
| 이랑 / 랑 | 이랑 after consonant, 랑 after vowel | Casual / colloquial | 오빠랑 밥 먹었어요 Ate with my older brother |
| 와 / 과 | 와 after vowel, 과 after consonant | Formal / written | 선생님과 상담했어요 Consulted with the teacher |
9 To/From Someone: -한테, -한테서
When saying you gave something to a person or received something from a person, Korean uses specific particles. These are different from the location particles 에 and 에서.
| Particle | Meaning | Used with | Formal equivalent |
|---|---|---|---|
| -한테 | to (a person) | People, animals | -에게 |
| -한테서 | from (a person) | People, animals | -에게서 |
| -에 | to (a place/object) | Places, things | -에 |
| -에서 | from (a place) | Places | -에서 |
10 Telling Time (시간 말하기)
Korean uses a mix of two number systems for time: Sino-Korean numbers for minutes (분) and Native Korean numbers for hours (시). Mastering this distinction is essential!
| Time | Korean | Romanization |
|---|---|---|
| 1:00 | 한 시 | han si |
| 2:00 | 두 시 | du si |
| 3:00 | 세 시 | se si |
| 4:00 | 네 시 | ne si |
| 5:00 | 다섯 시 | daseot si |
| 6:00 | 여섯 시 | yeoseot si |
| 7:00 | 일곱 시 | ilgop si |
| 8:00 | 여덟 시 | yeodeol si |
| 9:00 | 아홉 시 | ahop si |
| 10:00 | 열 시 | yeol si |
| 11:00 | 열한 시 | yeolhan si |
| 12:00 | 열두 시 | yeoldu si |
11 Counters (단위 명사)
Korean uses specific counting words (counters or classifiers) depending on what is being counted. The counter follows the number, and Native Korean numbers are used with most counters.
| Counter | Used for | Example | Translation |
|---|---|---|---|
| 개 | General objects / things | 사과 세 개 | Three apples |
| 명 | People (neutral) | 학생 다섯 명 | Five students |
| 분 | People (honorific) | 손님 두 분 | Two guests |
| 마리 | Animals | 고양이 한 마리 | One cat |
| 권 | Books, bound volumes | 책 세 권 | Three books |
| 장 | Flat sheets (paper, tickets) | 종이 두 장 | Two sheets of paper |
| 잔 | Cups, glasses of liquid | 커피 두 잔 | Two cups of coffee |
| 병 | Bottles | 물 한 병 | One bottle of water |
| 번 | Times / turns / occurrences | 세 번 봤어요 | Saw it three times |
| 살 | Age (years old) | 스물다섯 살 | 25 years old |
| 층 | Floors of a building | 삼 층 | Third floor |
| 대 | Vehicles, machines | 자동차 두 대 | Two cars |
12 Present Progressive: -고 있어요
To say someone is currently doing something, attach -고 있어요 to the verb stem. This is equivalent to the English "-ing" continuous form.
| Dictionary Form | Present Progressive | English |
|---|---|---|
| 먹다 | 먹고 있어요 | is eating |
| 가다 | 가고 있어요 | is going |
| 자다 | 자고 있어요 | is sleeping |
| 공부하다 | 공부하고 있어요 | is studying |
| 읽다 | 읽고 있어요 | is reading |
| 일하다 | 일하고 있어요 | is working |
13 Self Introduction (자기소개)
Knowing how to introduce yourself is one of the most practical Korean skills. Here is the vocabulary you need and a complete template to follow.
| Korean | Romanization | English |
|---|---|---|
| 이름 | ireum | Name |
| 나이 | nai | Age |
| 나라 | nara | Country |
| 직업 | jigeop | Job / Occupation |
| 취미 | chwimi | Hobby |
| 전공 | jeongong | Major (in school) |
| 고향 | gohyang | Hometown |
14 Dates and Months (날짜)
Korean dates use Sino-Korean numbers throughout — for years (년), months (월), and days (일). The order is: Year → Month → Day.
| Month | Korean | Romanization |
|---|---|---|
| January | 일월 | irwol |
| February | 이월 | iwol |
| March | 삼월 | samwol |
| April | 사월 | sawol |
| May | 오월 | owol |
| June | 유월 | yuwol |
| July | 칠월 | chirwol |
| August | 팔월 | parwol |
| September | 구월 | guwol |
| October | 시월 | siwol |
| November | 십일월 | sibirwol |
| December | 십이월 | sibiwol |
15 Degree Adverbs (정도 부사)
Degree adverbs modify adjectives and verbs to express how much. They are placed directly before the word they modify.
| Korean | Romanization | Meaning | Example Sentence |
|---|---|---|---|
| 조금 | jogeum | A little / slightly | 조금 매워요 — It's a little spicy |
| 좀 | jom | A little (softer/casual) | 좀 도와주세요 — Please help me a bit |
| 정말 | jeongmal | Really / truly | 정말 맛있어요 — It's really delicious |
| 진짜 | jinjja | Really / genuinely (casual) | 진짜 멋있다 — That's genuinely cool |
| 아주 | aju | Very | 아주 좋아요 — Very good |
| 많이 | mani | A lot / much | 많이 먹었어요 — I ate a lot |
| 별로 | byeolro | Not really (+ negative verb) | 별로 안 좋아요 — I don't really like it |
| 전혀 | jeonhyeo | Not at all (+ negative verb) | 전혀 모르겠어요 — I have no idea at all |
16 Making Verbs Into Nouns: -는 것
Adding -는 것 to a verb stem turns the verb into a noun phrase — the act of doing something. This is called nominalization and is extremely common in Korean.
| Tense | Pattern | Example | Meaning |
|---|---|---|---|
| Present / Habitual | -는 것 | 먹는 것 | the act of eating |
| Past | -(으)ㄴ 것 | 먹은 것 | the thing (that was) eaten |
| Future / Planned | -(으)ㄹ 것 | 먹을 것 | the thing to eat / will eat |
17 More … Than …: -보다 더
To compare two things in Korean, use the structure: [A]가/이 [B]보다 더 [adjective] — meaning "A is more [adjective] than B."
18 To Like: 좋다 vs 좋아하다
Two words that learners often confuse: 좋다 (to be good / feel good) is an adjective, while 좋아하다 (to like) is a verb. They take different particles!
| Word | Type | Particle Used | Example | Translation |
|---|---|---|---|---|
| 좋다 | Adjective (to be good) | Subject: 이/가 | 한국이 좋아요 | Korea is good / I feel good about Korea |
| 좋아하다 | Verb (to like) | Object: 을/를 | 한국을 좋아해요 | I like Korea |
| 싫다 | Adjective (to feel bad/averse) | Subject: 이/가 | 이 음식이 싫어요 | I don't like this food / feel averse to it |
| 싫어하다 | Verb (to dislike) | Object: 을/를 | 이 음식을 싫어해요 | I dislike this food |
19 Still, Already: 아직, 벌써
These two time adverbs are essential for expressing whether something has happened yet or is still ongoing.
20 Someone, Something, Somewhere: 누군가, 무언가, 어딘가, 언젠가
Korean has specific words for indefinite references (someone, something, somewhere) and their negative counterparts used with negative verbs.
| Korean | Romanization | Meaning | Example |
|---|---|---|---|
| 누군가 | nugunga | Someone | 누군가 왔어요 Someone came |
| 무언가 / 뭔가 | mueonga / mwonga | Something | 뭔가 이상해요 Something is strange |
| 어딘가 | eodinga | Somewhere | 어딘가 가고 싶어요 I want to go somewhere |
| 언젠가 | eonjenga | Someday / sometime | 언젠가 만나요 Let's meet someday |
| 아무도 | amudo | Nobody (+ negative verb) | 아무도 없어요 Nobody is here |
| 아무것도 | amugeotdo | Nothing (+ negative verb) | 아무것도 안 먹었어요 I ate nothing |
| 아무데도 | amudedo | Nowhere (+ negative verb) | 아무데도 안 갔어요 I went nowhere |
21 Imperative: -(으)세요
To make a polite request or command ("Please do..."), attach -(으)세요 to the verb stem. This is the standard polite imperative used with adults and in public situations.
| Dictionary Form | Rule | Imperative | Meaning |
|---|---|---|---|
| 오다 | vowel stem → 세요 | 오세요 | Please come |
| 앉다 | consonant stem → 으세요 | 앉으세요 | Please sit |
| 드시다 | honorific for 먹다 | 드세요 | Please eat (honorific) |
| 보다 | vowel stem → 세요 | 보세요 | Please look / watch |
| 기다리다 | vowel stem → 세요 | 기다리세요 | Please wait |
| 말하다 | 하다 → 하세요 | 말하세요 | Please speak |
22 Don't Do It: -지 마세요
To tell someone politely not to do something, use [verb stem] + 지 마세요. This pattern works with any verb.
23 Method, Way, Direction: -(으)로
The particle -(으)로 is versatile: it marks direction toward somewhere, the means or method of doing something, and the material something is made of.
| Use | Meaning | Korean Example | Translation |
|---|---|---|---|
| 1. Direction | toward / in the direction of | 서울로 가요 | Going toward Seoul |
| 2. Means / Method | by / using / in (language) | 버스로 가요 | Going by bus |
| 2. Method cont. | in (a language) | 한국어로 말해요 | Speaking in Korean |
| 2. Method cont. | with (a tool) | 젓가락으로 먹어요 | Eating with chopsticks |
| 3. Material | made of / from | 나무로 만들었어요 | Made of wood |
24 To be Good/Poor at: 잘하다, 못하다
Use 잘하다 to say someone does something well, and 못하다 or 잘 못하다 to say they do it poorly or cannot do it.
| Korean | Romanization | Meaning | Example |
|---|---|---|---|
| 잘하다 | jalhada | To do well / be good at | 한국어를 잘해요 I am good at Korean |
| 못하다 | mothada | To be unable to / do poorly | 수영을 못해요 I can't swim / am bad at swimming |
| 잘 못하다 | jal mothada | To not be good at | 노래를 잘 못해요 I'm not good at singing |
| 잘 + verb | jal + verb | To do [verb] well | 잘 자요 Sleep well |
25 All, More: 다, 더
다 means "all" or "entirely" (completion), while 더 means "more" (addition). Both are simple but extremely frequent in everyday Korean.
26 Also, Too: -도 (Advanced Uses)
Beyond the basic "also/too" meaning covered in Section 2, the particle -도 has several advanced uses that give your Korean a more natural, native-like feel.
| Use | Meaning | Korean Example | Translation |
|---|---|---|---|
| 1. Even | Emphasizes inclusion of unexpected subject | 아이도 알아요 | Even children know (it) |
| 2. Both…and | -기도 하고 -기도 하다 | 좋기도 하고 나쁘기도 해요 | It's both good and bad |
| 3. Not even | Emphatic negation with quantity | 하나도 없어요 | There isn't even one |
| 4. Also/Sometimes | verb + 기도 하다 = also does / sometimes does | 먹기도 해요 | I also eat it / I sometimes eat it |
