Korean grammar for beginners rests on 5 basics: verb-last word order, particles, verb endings, politeness and tense. Learn those and you can build a real sentence on day one, like 저는 커피를 마셔요 (jeoneun keopireul masyeoyo, “I drink coffee”). For English speakers the good news is that Korean grammar is very regular, so one rule usually covers hundreds of verbs.
Key takeaways
- The verb always comes last. 저는 커피를 마셔요 is literally “I coffee drink.”
- Particles depend on the final sound: 은, 이 and 을 follow a consonant, while 는, 가 and 를 follow a vowel.
- Learn the polite -아요/-어요 ending first. It works in shops, taxis and with strangers.
- Past tense adds one syllable: 먹어요 (I eat) becomes 먹었어요 (I ate).
Korean grammar for beginners: the 5 rules in one table
Every sentence you’ll meet in a textbook, a K-drama subtitle or a Seoul subway announcement uses these five mechanisms together. Here they are side by side, with one example each.
| Basic | What it does | Example | Romanization | Meaning |
|---|---|---|---|---|
| Word order | Subject, then object, verb last (SOV) | 저는 밥을 먹어요 | jeoneun babeul meogeoyo | I eat rice |
| Particles | Small tags that show each noun’s role | 친구가 와요 | chinguga wayo | My friend is coming |
| Verb endings | Stem plus ending carries the meaning | 가다 → 가요 | gada → gayo | to go → (I) go |
| Politeness | The ending changes with the listener | 감사합니다 / 고마워 | gamsahamnida / gomawo | Thank you (formal / casual) |
| Tense | A syllable slots in before the ending | 먹었어요 | meogeosseoyo | I ate |
Some things are easier than in English. Korean has no articles (no “a” or “the”), no grammatical gender, and plurals are optional: 책 (chaek) can mean “book” or “books,” and you add -들 (-deul) only to stress that there are several. Verbs don’t change for person. 가요 means “I go,” “you go,” “she goes” and “they go,” and context tells you who.
The hard part is everything that happens at the end of the sentence. Korean stacks its meaning there (tense, negation, politeness, whether it’s a question), so you have to listen to the last word before you know what’s being said.
Why Korean word order puts the verb last
Korean is a subject-object-verb (SOV) language, like Japanese and Turkish. English goes subject-verb-object. So “I study Korean” becomes 저는 한국어를 공부해요 (jeoneun hangugeoreul gongbuhaeyo), word for word “I Korean study.”
What SOV means in a longer sentence
Extra details go between the subject and the verb, usually in this order: who, when, where, what, then the verb.
- 저는 오늘 학교에서 한국어를 공부해요 (jeoneun oneul hakgyoeseo hangugeoreul gongbuhaeyo): “I study Korean at school today.”
Describing words also come before what they describe, every time. A big house is 큰 집 (keun jip), “big house,” and this holds even for long clauses: “the coffee I drank yesterday” comes out as “yesterday I-drank coffee.” If you can accept that the important word arrives last, a lot of Korean starts to make sense.
Can you change Korean word order?
Mostly, yes, as long as the verb stays at the end. Particles show who does what, so 한국어를 저는 공부해요 still means “I study Korean,” just with “Korean” emphasized. In casual speech people sometimes add an afterthought after the verb, but as a beginner, put the verb last.
Koreans also drop whatever is obvious. 어디 가요? (eodi gayo?) means “Where are you going?” though there’s no “you” in it. 먹었어요 (meogeosseoyo) can be a complete answer: “(I) ate.” Leaving out the subject is normal, and your Korean will sound more natural if you do the same.
Korean particles explained: 은/는, 이/가, 을/를 and more
Particles (조사, josa) are short endings stuck onto nouns that tell you what job each noun does. Most come in pairs, and you choose one by checking whether the noun ends in a consonant or a vowel. Hangul (한글, the Korean alphabet) makes this easy to see, because a final consonant sits at the bottom of the syllable block.
| Job | After a consonant | After a vowel | Example |
|---|---|---|---|
| Topic | 은 (eun) | 는 (neun) | 저는 (jeoneun), “as for me” |
| Subject | 이 (i) | 가 (ga) | 친구가 (chinguga), “a friend (does)” |
| Object | 을 (eul) | 를 (reul) | 밥을 (babeul), “rice (as object)” |
| And / with | 과 (gwa) | 와 (wa) | 빵과 우유 (ppanggwa uyu), “bread and milk” |
Topic vs subject: should you use 은/는 or 이/가?
This is the question every learner asks. A rough rule: 은/는 marks what you’re talking about (“as for…”) or sets up a contrast, and 이/가 points at who or what does something, usually as new information.
- 누가 왔어요? 민수가 왔어요. (nuga wasseoyo? minsuga wasseoyo.) “Who came? Minsu came.” Minsu is the new information, so the sentence uses 가.
- 저는 학생이에요 (jeoneun haksaengieyo): “I’m a student.” Here “I” is the topic, so 는.
- 시간이 없어요 (sigani eopseoyo): “I don’t have time.” Verbs of having, lacking and liking usually take 이/가.
Note two irregular forms: 저 (jeo, polite “I”) plus 가 becomes 제가 (jega), and casual 나 (na) becomes 내가 (naega).
Object particle 을/를
This one is simple. It marks what the action is done to: 커피를 마셔요 (keopireul masyeoyo), “drink coffee”; 책을 읽어요 (chaegeul ilgeoyo), “read a book.” In casual speech it often gets dropped, so 커피 마셔요 is fine among friends.
Place and time: 에 vs 에서
Beginners mix these two up more than any other pair. 에 (e) marks where something is, where you’re going, or when something happens. 에서 (eseo) marks where an action takes place, and it can also mean “from.”
- 집에 있어요 (jibe isseoyo): “I’m at home.” This is about being somewhere, so 에.
- 집에서 쉬어요 (jibeseo swieoyo): “I rest at home.” Resting is an action, so 에서.
- 학교에 가요 (hakgyoe gayo): “I go to school.” A destination takes 에.
- 세 시에 만나요 (se sie mannayo): “Let’s meet at three.” For telling the time, see our guide to native and Sino-Korean numbers.
A few more you’ll see constantly: 도 (do, “also”) as in 저도 (jeodo, “me too”); 의 (ui, possessive, often pronounced “e”); 하고 (hago, “and/with,” the spoken favorite); and 한테 (hante, “to a person”), as in 친구한테 줬어요 (chinguhante jwosseoyo), “I gave it to a friend.”
How Korean verbs work: stem plus ending
Each Korean verb has a dictionary form ending in 다 (da): 가다 (gada, to go), 먹다 (meokda, to eat), 하다 (hada, to do). Nobody actually says these forms in conversation. To use a verb, drop 다 to get the stem, then attach an ending.
The 아요/어요 rule that covers most verbs
For the everyday polite form, look at the last vowel of the stem:
- If it’s ㅏ or ㅗ, add 아요: 보다 → 보 + 아요 → 봐요 (bwayo, “see”). With 가다 the two vowels merge: 가요 (gayo).
- If it’s any other vowel, add 어요: 먹다 → 먹어요 (meogeoyo); 마시다 → 마셔요 (masyeoyo).
- If the verb ends in 하다, it becomes 해요: 공부하다 → 공부해요 (gongbuhaeyo, “study”).
The 하다 rule alone gives you hundreds of verbs, since Korean makes many of them by putting 하다 after a noun: 운동하다 (undonghada, exercise), 요리하다 (yorihada, cook), 쇼핑하다 (syopinghada, shop).
Adjectives conjugate like verbs
In Korean, “expensive” and “delicious” behave like verbs. 비싸다 becomes 비싸요 (bissayo, “it’s expensive”), and 맛있다 becomes 맛있어요 (masisseoyo, “it’s delicious”). You don’t need a separate “is.”
There are some irregular verbs, and they change a letter before the ending. 덥다 (hot) becomes 더워요 (deowoyo), and 듣다 (listen) becomes 들어요 (deureoyo). Learn these as you meet them rather than memorizing lists.
How to say “to be” in Korean: 이에요/예요 and 있어요
To say “X is Y” with nouns, add 이에요 after a consonant or 예요 after a vowel: 학생이에요 (haksaengieyo, “I’m a student”), 의사예요 (uisayeyo, “I’m a doctor”). Existence is a separate verb. 있어요 (isseoyo) means “there is” or “I have,” and 없어요 (eopseoyo) means “there isn’t” or “I don’t have.” You’ll use 있어요? at every shop counter to ask whether they have something.
Korean politeness levels: which one to learn first
Grammar books list up to seven speech levels (the endings that show how formal you’re being), but daily life uses three. The same idea can take a different ending depending on who you’re talking to:
| English | Korean | Romanization | When to use it |
|---|---|---|---|
| Thank you (formal polite) | 감사합니다 | gamsahamnida | Shop staff, elders, work, announcements |
| Thank you (polite) | 고마워요 | gomawoyo | People you know, polite but warm |
| Thanks (casual) | 고마워 | gomawo | Close friends, younger people |
| I’m a student (formal polite) | 학생입니다 | haksaengimnida | Self-introductions, interviews, speeches |
| I’m a student (polite) | 학생이에요 | haksaengieyo | Default with strangers |
| I’m a student (casual) | 학생이야 | haksaengiya | Friends your age |
| Please go / Goodbye (polite, honorific) | 가세요 | gaseyo | Showing respect to the person doing the action |
| Are you going? (formal polite) | 갑니까? | gamnikka? | Formal settings, news, service scripts |
해요체, the polite style to start with
The -아요/-어요 form you just learned is called 해요체 (haeyo-che, polite style). It’s polite without being stiff, and you can use it with shopkeepers, taxi drivers, coworkers and anyone you’ve just met. Start here and use it everywhere until someone invites you to speak more casually.
합니다체 and 반말
The formal style, 합니다체 (hamnida-che), is what you hear on the news, in airline announcements and at job interviews. Its rule is simple: a stem ending in a vowel takes ㅂ니다 (가다 → 갑니다, gamnida), and a stem ending in a consonant takes 습니다 (먹다 → 먹습니다, meokseumnida). Questions end in -ㅂ니까/-습니까.
반말 (banmal, casual speech) basically drops the 요: 먹어요 becomes 먹어, and 가요 becomes 가. Use it only with close friends, younger people who are fine with it, or when someone suggests it. Our guide to Korean slang shows how casual texting Korean builds on banmal.
The syllable -시- (-si-) adds respect toward the person you’re talking about, not toward your listener. 가요 means “goes,” while 가세요 shows respect for whoever is going. That’s why shop staff say it to you.
Korean tenses: past, present and future in 3 patterns
Korean tense comes in one piece at a time, and like everything else it goes on the verb.
Present tense
The 해요 form covers the present, habits and often the near future. 내일 가요 (naeil gayo) means “I’m going tomorrow,” with no extra future marker needed.
Past tense: 았/었/했
Use the same vowel logic as before, then add 어요:
- ㅏ/ㅗ stems add 았: 가다 → 갔어요 (gasseoyo, “went”)
- Other stems add 었: 먹다 → 먹었어요 (meogeosseoyo, “ate”); 마시다 → 마셨어요 (masyeosseoyo, “drank”)
- 하다 becomes 했: 공부하다 → 공부했어요 (gongbuhaesseoyo, “studied”)
Future tense: -(으)ㄹ 거예요
Add ㄹ 거예요 to a stem ending in a vowel and 을 거예요 to a stem ending in a consonant. 가다 becomes 갈 거예요 (gal geoyeyo, “will go”), and 먹다 becomes 먹을 거예요 (meogeul geoyeyo, “will eat”). This is the form for plans and predictions.
Progressive: -고 있어요
For an action happening right now, add 고 있어요 to the stem: 먹고 있어요 (meokgo isseoyo), “I’m eating.” It’s the closest match to English “-ing.”
How to make negative sentences and questions in Korean
Korean has two everyday ways to say “not” and a separate word for “can’t.” They’re easy to mix up.
안 vs -지 않아요
Put 안 (an) before the verb: 안 먹어요 (an meogeoyo), “I don’t eat.” Or add -지 않아요 to the stem: 먹지 않아요 (meokji anayo). They mean the same thing. 안 is shorter and more common in speech, and -지 않아요 sounds a bit more careful. With noun-plus-하다 verbs, 안 goes right before 해요: 공부 안 해요 (gongbu an haeyo), “I don’t study.”
못: when you can’t
못 (mot) means you can’t, either because you’re unable or because something stops you. 매운 거 못 먹어요 (maeun geo mot meogeoyo) means “I can’t eat spicy food,” which is a very useful sentence in Korea. Saying 안 먹어요 here would mean you choose not to, which is different.
Negating nouns and “having”
Nouns use 아니에요 (anieyo): 학생이 아니에요 (haksaengi anieyo), “I’m not a student.” For not having something, swap 있어요 for 없어요.
How to ask a question in Korean
In polite style, a question is just the statement with rising intonation. 먹어요 means “I eat,” and 먹어요? means “Do you eat?” In writing, add a question mark. Question words sit where the answer would go: 뭐 먹어요? (mwo meogeoyo?), “What are you eating?” Formal style is the exception and changes the ending to -ㅂ니까/-습니까.
Worked example: building one Korean sentence step by step
Now put all five rules together. Target: “I’m going to eat tteokbokki (떡볶이, spicy rice cakes) with a friend in Myeongdong tomorrow.” Myeongdong (명동) is a shopping district in central Seoul known for street food.
- Topic first: 저는 (jeoneun), “as for me.”
- Time next: 내일 (naeil), “tomorrow.” Words like this don’t need 에.
- Who with: 친구하고 (chinguhago), “with a friend.”
- Where the action happens: 명동에서 (myeongdongeseo). Eating is an action, so the place takes 에서, not 에.
- Object: 떡볶이를 (tteokbokkireul). 떡볶이 ends in a vowel, so it takes 를.
- Verb last, future tense: 먹 + 을 거예요 → 먹을 거예요.
Result: 저는 내일 친구하고 명동에서 떡볶이를 먹을 거예요. (jeoneun naeil chinguhago myeongdongeseo tteokbokkireul meogeul geoyeyo.)
To change the meaning, you only change the end of the sentence:
- Past (“yesterday I ate”): change 내일 to 어제 (eoje) and 먹을 거예요 to 먹었어요.
- Negative: 안 먹을 거예요, “I’m not going to eat.”
- Formal: 먹을 겁니다 (meogeul geomnida).
- Casual with a friend: 나 내일 친구랑 명동에서 떡볶이 먹을 거야. 저 changes to 나, 하고 becomes the chattier 랑, the object particle disappears, and the 요 goes.
Those four variations show how Korean works. You build the core sentence once, and the ending does the rest.
Common Korean grammar mistakes beginners make
- Saying 저는 in every sentence. It’s grammatically correct but sounds robotic. Once the topic is clear, drop it.
- Using the dictionary form in speech. 먹다 is a dictionary entry. In conversation you say 먹어요.
- Swapping 에 and 에서. Ask whether you’re doing something there (에서) or just being or going there (에).
- Putting 은/는 on everything. When you answer “who” or “what” with new information, use 이/가.
- Using English word order. “I eat kimchi” does not become 저는 먹어요 김치. The verb still goes last.
- Switching to banmal too early. Casual speech with someone older or someone you’ve just met can come across as rude. Wait until they suggest it.
- Relying on romanization. Particle choice depends on the final consonant you see in Hangul. Romanization hides it and confuses pronunciation.
FAQ
Is Korean grammar hard for English speakers?
The structure is unfamiliar at first, since the verb comes last, particles replace prepositions and politeness is part of the grammar. The rules themselves are unusually regular, though, and there are no articles, genders or verb changes for person. Most learners say the first few weeks are the hardest, and things speed up once SOV order starts to feel normal.
Should I learn Hangul before Korean grammar?
Yes. Hangul has 24 basic letters (14 consonants and 10 vowels) and was created under King Sejong in the 15th century to be easy to learn. Many people learn to read it within a few days of focused study. You need it for grammar anyway, because particle choice depends on the final consonant of the syllable block.
What is the difference between 은/는 and 이/가?
은/는 marks the topic (“as for…”) or a contrast. 이/가 marks the subject, often as new information or the answer to “who?” Start with 저는 for introductions and 이/가 with 있어요, 없어요 and 좋아요, then refine your sense of it by listening.
Which Korean politeness level should I learn first?
Learn the polite -아요/-어요 style (해요체) first. It works with strangers, shop staff and coworkers, and you can understand the other levels once you know it. Add the formal -ㅂ니다 style for presentations and casual banmal for close friends later.
How do you say “I” and “you” in Korean?
Use 저 (jeo) for the polite “I” and 나 (na) for the casual one. For “you,” Koreans usually say the person’s name with 씨 or their title, or just leave “you” out. 당신 exists, but in conversation it can sound cold or confrontational.
Is there an official Korean grammar test?
Yes. TOPIK (Test of Proficiency in Korean) is the standard test for non-native speakers and is held in many countries. Test dates, levels and registration change, so check the official TOPIK website. The King Sejong Institute (세종학당), a government-backed language school network, also runs classes abroad, and its official site lists locations.
What to study after these Korean grammar basics
Once these five rules feel automatic, learn connectors, which let you join two ideas instead of speaking in short single sentences:
- -고 (and): 싸고 맛있어요 (ssago masisseoyo), “It’s cheap and delicious.”
- -지만 (but): 비싸지만 맛있어요 (bissajiman masisseoyo), “It’s expensive but delicious.”
- -아서/어서 (so, because): 배고파서 먹었어요 (baegopaseo meogeosseoyo), “I was hungry, so I ate.”
- -고 싶어요 (want to): 한국에 가고 싶어요 (hanguge gago sipeoyo), “I want to go to Korea.”
- -(으)ㄹ 수 있어요 (can): 할 수 있어요 (hal su isseoyo), “I can do it.”
After that, learn counters and the two number systems, since you’ll need them to order food or say your age. Turn on Korean subtitles for a show you already know, and watch the last word of each line. That’s where tense, negation and politeness show up, and you’ll start to hear the patterns from this guide.
