Korean Particles: The 8 Most Common Markers Explained
Particles are the part of Korean grammar that stops most adult learners cold. English doesn't have them, so the rules don't translate directly. The good news: there are about eight particles you really need, the choice between consonant-attached and vowel-attached forms is mechanical, and once the patterns click, they click for everything you read and hear. This guide walks through each particle in the order Korean teachers typically introduce them, with 40+ example sentences pulled from everyday Korean and K-content.

What is a Korean particle?
A particle (조사, josa) is a short suffix that attaches to a noun to mark its role in the sentence: subject, object, topic, location, time, possession, inclusion, exclusion. Korean is an SOV (subject-object-verb) language with relatively free word order. The verb almost always sits at the end, but the other parts of the sentence can rearrange. The particles tell you who's doing what, even when the order changes.
Compare these two English sentences: The cat chased the dog, and The dog chased the cat. Same words, opposite meanings — English relies on word order. Korean would mark the cat-noun and dog-noun with particles, and you could swap the order without changing who chased whom. The cost of that flexibility: you have to learn the particles. The benefit: once you do, Korean stops feeling like rearranged English and starts feeling like its own grammar.
Most particles change form depending on whether the noun ends in a consonant or a vowel. 은/는, 이/가, 을/를, 와/과 are all the same particle written two ways: pick the version that flows better off the previous sound. The single-form particles (에, 에서, 도, 만, 의, 부터, 까지) attach to any noun without changing.
1. Topic markers: 은 / 는
The topic marker introduces what the sentence is about. The closest English paraphrase is 'as for X' or 'speaking of X'. 은 attaches to nouns ending in a consonant; 는 attaches to nouns ending in a vowel. 은/는 is the particle that signals 'old information' — what we're already talking about — and it's the first particle most textbooks introduce.
| Particle | After consonant | After vowel | Use |
|---|---|---|---|
| 은 / 는 | 은 | 는 | Topic marker. Marks 'as for X' — what the sentence is about. |
Examples
Jeoneun haksaeng-ieyo.
I'm a student. (As for me, [I'm] a student.)
Oneureun nalssi-ga joa-yo.
The weather is nice today. (As for today, the weather is nice.)
한국 음식은 맛있어요.
Hanguk eumsig-eun masisseoyo.
Korean food is delicious. (As for Korean food, [it's] delicious.)
영화는 재미있어요.
Yeonghwa-neun jaemiisseoyo.
The movie is fun. (As for the movie, [it's] fun.)
저는 미국 사람이에요.
Jeoneun Miguk saram-ieyo.
I'm American.
Note: 은/는 also marks contrast: 저는 가요. 친구는 안 가요. (I'm going. My friend isn't.)
2. Subject markers: 이 / 가
The subject marker identifies the doer or the new piece of information. 이 attaches to consonant-final nouns; 가 attaches to vowel-final nouns. The big confusion adult learners hit is that BOTH 은/는 and 이/가 can sit on the subject of a sentence — but they communicate different things. 은/는 says 'about this'. 이/가 says 'this is the one'.
| Particle | After consonant | After vowel | Use |
|---|---|---|---|
| 이 / 가 | 이 | 가 | Subject marker. Marks the new information / who or what is doing the action. |
Examples
비가 와요.
Bi-ga wa-yo.
It's raining. (Rain is coming.)
Chingu-ga wasseoyo.
A friend came. (A friend, specifically.)
I chaek-i jaemiisseoyo.
This book is fun. (This book, specifically.)
Seonsaengnim-i Hanguk saram-ieyo.
The teacher is Korean. (The teacher specifically.)
Mul-i chagawoyo.
The water is cold.
Note: 이/가 typically introduces something new. 은/는 typically continues a known topic. The difference is the heart of Korean particle grammar.
은/는 vs 이/가 — the most-asked question in Korean grammar
If you've made it to particle Wikipedia rabbit holes, this is the corner you keep returning to. Here's the cleanest way to think about it.
| Use 은/는 when… | Use 이/가 when… |
|---|---|
| The noun is what the sentence is ABOUT (topic). | The noun is the new or specific information (subject focus). |
| You're contrasting two things. | You're answering 'who?' or 'what?'. |
| The noun is already known to both speakers. | The noun is being introduced for the first time. |
| You're stating a general fact. | You're describing a specific event happening now. |
Side-by-side examples
A: 누가 학생이에요? — Who is the student?
B: 제가 학생이에요. — I am the student.
제가 (이/가): identifying which person.
A: 자기 소개 좀 해주세요. — Please introduce yourself.
B: 저는 학생이에요. — I'm a student.
저는 (은/는): general topic — talking about myself.
비가 와요. — It's raining.
비가 (이/가): a new event happening; rain is the new info.
비는 한국에서 7월에 많이 와요. — As for rain, it falls a lot in Korea in July.
비는 (은/는): generalizing about rain as a topic.
저는 김치를 좋아하지만 친구는 안 좋아해요. — I like kimchi, but my friend doesn't.
은/는 used twice for explicit contrast.
3. Object markers: 을 / 를
The object marker tags the noun being acted on. 을 follows consonant-final nouns; 를 follows vowel-final nouns. Object marking is more grammatical and less discourse-loaded than the topic/subject distinction, and it's the particle that's most freely dropped in casual speech.
| Particle | After consonant | After vowel | Use |
|---|---|---|---|
| 을 / 를 | 을 | 를 | Object marker. Marks what is being acted on by the verb. |
Examples
Jeoneun kimchi-reul joahae-yo.
I like kimchi.
Chaeg-eul ilgeoyo.
I read a book.
Mul-eul masyeo-yo.
I drink water.
Hangugeo-reul gongbu-hae-yo.
I study Korean.
Chingu-reul manna-yo.
I meet a friend.
Note: In casual spoken Korean, 을/를 is often dropped: 김치 좋아해. (I like kimchi.) The drop is allowed when the object is obvious from context.
4. Location particles: 에 vs 에서
Korean splits 'at/in/to' into two particles based on whether your sentence is about being SOMEWHERE or DOING SOMETHING somewhere. 에 marks static location, destination, or time. 에서 marks the location where an action takes place, or the origin point.
에 (location: where you are or where you're going)
에 attaches to time and place nouns. Three common uses: where you are right now (있어요, 살아요), where you're going (가요, 와요), and when something happens (몇 시에, 몇 월에). 에 doesn't change form.
| Particle | After consonant | After vowel | Use |
|---|---|---|---|
| 에 | 에 | 에 | Location: destination, time, or static existence (where something IS). |
Examples
Hakgyo-e ga-yo.
I go to school. (Destination)
집에 있어요.
Jib-e isseoyo.
I'm at home. (Static location)
세 시에 만나요.
Se si-e manna-yo.
Let's meet at 3 o'clock. (Time)
서울에 살아요.
Seoul-e sara-yo.
I live in Seoul.
한국에 갈 거예요.
Hanguk-e gal geoyeyo.
I'll go to Korea.
에서 (location: where the action happens, or where it's from)
에서 marks the place where a verb's action takes place — studying at school, working at a cafe, watching a movie at home. It also marks origin: 한국에서 왔어요 means 'I came from Korea'. The shorthand is: with stative verbs use 에, with action verbs use 에서.
| Particle | After consonant | After vowel | Use |
|---|---|---|---|
| 에서 | 에서 | 에서 | Location: where an action happens, or origin (from where). |
Examples
Hakgyo-eseo gongbu-hae-yo.
I study at school. (Action happens there)
집에서 영화를 봐요.
Jib-eseo yeonghwa-reul bwa-yo.
I watch a movie at home.
한국에서 왔어요.
Hanguk-eseo wasseoyo.
I came from Korea.
카페에서 친구를 만나요.
Kape-eseo chingu-reul manna-yo.
I meet a friend at a cafe.
어디에서 일해요?
Eodi-eseo ilhae-yo?
Where do you work?
5–8. Other essential particles
Beyond the topic/subject/object/location set, four more particles cover most of what you need for everyday speech: 와/과 (with/and), 도 (also), 만 (only), and 부터/까지 (from/to). Together they cover inclusion, exclusion, and ranges.
5. 와 / 과
And / with. Connects nouns or marks 'with whom'.
| Particle | After consonant | After vowel | Use |
|---|---|---|---|
| 와 / 과 | 과 | 와 | And / with. Connects nouns or marks 'with whom'. |
Examples
친구와 영화를 봐요.
Chingu-wa yeonghwa-reul bwa-yo.
I watch a movie with a friend.
빵과 우유.
Ppang-gwa uyu.
Bread and milk.
엄마와 아빠.
Eomma-wa appa.
Mom and dad.
Note: Spoken Korean often uses 하고 (-hago) or 랑/이랑 (-rang/-irang) instead. 친구하고 / 친구랑 are more casual than 친구와.
6. 도
Also / too. Replaces the topic or subject particle.
| Particle | After consonant | After vowel | Use |
|---|---|---|---|
| 도 | 도 | 도 | Also / too. Replaces the topic or subject particle. |
Examples
저도 한국 사람이에요.
Jeo-do Hanguk saram-ieyo.
I'm also Korean.
Kimchi-do joahae-yo.
I like kimchi too.
Oneul-do gongbu-hae-yo.
I'm studying today too.
Note: 도 attaches directly to the noun and replaces 은/는 or 이/가. Don't stack them: write 저도, not 저는도 or 저가도.
7. 만
Only / just.
| Particle | After consonant | After vowel | Use |
|---|---|---|---|
| 만 | 만 | 만 | Only / just. |
Examples
Mul-man juseyo.
Just water, please.
저만 알아요.
Jeo-man arayo.
Only I know.
주말에만 만나요.
Jumal-e-man manna-yo.
We meet only on weekends.
Note: 만 can stack with 에 (에만 = 'only at/in') and other particles for nuance. With 만, the verb often follows directly without 을/를.
8. 부터 / 까지
From / to (time and place range).
| Particle | After consonant | After vowel | Use |
|---|---|---|---|
| 부터 / 까지 | 부터 / 까지 | 부터 / 까지 | From / to (time and place range). |
Examples
9시부터 5시까지 일해요.
Ahop-si-buteo daseot-si-kkaji ilhae-yo.
I work from 9 to 5.
Wolyoil-buteo geumyoil-kkaji hakgyo-e ga-yo.
I go to school from Monday to Friday.
여기부터 저기까지.
Yeogi-buteo jeogi-kkaji.
From here to there.
Note: 부터 = starting point. 까지 = end point. Use them in pairs for ranges, or separately when only one boundary matters.
9. 의
Possessive / 'of'. Often dropped in spoken Korean.
| Particle | After consonant | After vowel | Use |
|---|---|---|---|
| 의 | 의 | 의 | Possessive / 'of'. Often dropped in spoken Korean. |
Examples
Jeo-ui chingu.
My friend.
한국의 수도는 서울이에요.
Hanguk-ui sudo-neun Seoul-ieyo.
Korea's capital is Seoul.
엄마의 사진.
Eomma-ui sajin.
Mom's photo.
Note: 의 is often dropped: 저 친구 = 저의 친구. When kept, 의 is usually pronounced 'e' (에) in modern Seoul speech, not 'ui'.
Common particle confusions
These five mix-ups are the ones Korean teachers hear from international students every semester. None of them are unfixable; all of them benefit from seeing the same contrast across multiple sentences.
은/는 vs 이/가 — the most common pain point
Use 은/는 when you're talking ABOUT something already known: 저는 학생이에요 (As for me, I'm a student). Use 이/가 when you're introducing NEW information or specifying which one: 누가 학생이에요? — 제가 학생이에요. (Who is the student? — I am.) The same noun can take either particle in different contexts. A native Korean teacher often summarizes the rule as: 은/는 is for old information or contrast, 이/가 is for new information or focus.
에 vs 에서
에 marks where something IS or where you are GOING. 에서 marks where an ACTION is taking place or where something is FROM. 학교에 가요 (go to school) but 학교에서 공부해요 (study AT school). 한국에 살아요 (live in Korea, static) but 한국에서 왔어요 (came FROM Korea, origin).
Can you drop 을/를?
In casual spoken Korean, yes — 김치 좋아해 instead of 김치를 좋아해. The drop is fine when the object is obvious. In writing or formal speech, keep 을/를. The same goes for the subject particle 이/가: it's frequently dropped in casual speech but kept in formal writing.
도 vs 까지 (also vs even)
도 means 'also/too' — 저도 가요 (I'm also going). 까지 in this nuance means 'even, going as far as' — 그 사람까지 왔어요? (Even THAT person came?). Both replace the topic/subject particle, but 까지 carries surprise or emphasis. Confusing them is a sign that a learner has memorized particles as standalone words rather than as discourse markers.
부터 vs 에서 (from + time vs from + place)
Both can translate as 'from', but they're not interchangeable. For time, use 부터: 9시부터 (from 9 o'clock). For place of origin, use 에서: 한국에서 왔어요 (I came from Korea). Korean grammar treats time and place differently here, even though English collapses them into 'from'.
Particles in K-drama and K-pop
Real Korean drops, stacks, and emphasizes particles in ways no textbook can cover comprehensively. The lines below show patterns you'll hear in actual dialogue and lyrics.
Common K-drama line
내가 좋아해.
It's me who likes [you]. / I'm the one who likes [you].
내가 (subject + emphasis) instead of 나는 — the speaker is identifying THEMSELVES as the one who likes the other person. With 나는, the same line would feel softer: 'Speaking of me, I like [you].'
Common K-drama line
왜 저한테만 그래요?
Why are you only [doing that] to me?
한테만: 한테 (to / toward a person) + 만 (only). Stacked particles are common in real Korean speech.
Common K-pop lyric pattern
너는 내 사랑이야.
You are my love.
너는 (topic) — the song is now about 'you'. Switching to 네가 (subject) would shift focus to identifying which person, less romantic.
Casual conversation
나도 그거 좋아해!
I like that too!
나도 (also-me): 도 replaces what would otherwise be 나는. You don't say 나는도.

Common questions
Why does Korean need particles when English doesn't?
Korean is a head-final SOV (subject-object-verb) language with relatively free word order. English fixes meaning through position — 'The cat chased the dog' and 'The dog chased the cat' mean different things. Korean fixes meaning through particles attached to each noun, so the order can rearrange without changing who did what. The price you pay for that flexibility is that every noun needs a marker. The benefit is that emphasis and topicality can be expressed structurally instead of through stress or extra words. Particles aren't a strange add-on; they're the load-bearing wall of Korean grammar.
Can I drop particles in casual speech?
Yes, and Koreans do it constantly. The most droppable particles in casual speech are the subject 이/가 and the object 을/를: 너 어디 가? (Where are you going?) instead of 너는 어디에 가? — both are correct, the second is more careful. The topic 은/는 is dropped less often because it carries discourse emphasis. Location 에/에서 is kept because dropping it would make the sentence ambiguous. Honorific particles (께서, 께) are never dropped in respectful speech because dropping them is the rude part. Rule of thumb: drop particles in casual conversation, keep them in writing or when speaking to someone older or higher-status.
What's the easiest way to remember 은/는 vs 이/가?
Two heuristics that hold up: (1) If you can paraphrase the noun with 'as for…' or 'speaking of…', use 은/는. If you can paraphrase as 'it is X who…' or 'the one who…', use 이/가. (2) When the noun is the topic of the conversation already (you've mentioned it, or it's about your own routine), 은/는. When you're identifying or introducing something new — answering 'who?' or 'what?' — 이/가. The same Korean sentence frequently works with either particle, and the meaning shifts subtly. Reading K-dramas with subtitles and noticing which particle the writer chose is one of the fastest ways to internalize the difference.
Are particles different in formal vs casual Korean?
The basic markers (은/는, 이/가, 을/를, 에, 에서) are the same. What changes is the honorific layer. In respectful speech, the subject particle 이/가 is replaced by 께서: 선생님께서 오셨어요 (The teacher came). The dative 한테 (to a person) is replaced by 께: 부모님께 드렸어요 (I gave it to my parents). Casual speech uses 한테 and 한테는 freely. The choice is socially loaded: using 께서 toward someone Korean culture treats as a peer can feel sarcastic; failing to use it toward an elder can feel rude.
Do K-pop songs use proper particles or skip them?
Both. K-pop lyrics regularly drop subject and object particles for rhythm and conciseness, especially in chorus lines. They keep particles when the line needs structural clarity — 'as for me' framing, contrast, or location. Lyrics also play with particle pairing: 너는 vs 네가 in the same song can shift the emotional center between 'about you' and 'it's you who'. Studying lyric particles next to a translation is a productive way to feel the discourse layer. Just don't take dropped particles as the standard — songs compress everything; written and spoken Korean don't.
How long does it take to feel comfortable with particles?
Most adult learners can recite the rules within a week and produce simple correct sentences within a month. Feeling them — picking the right particle without translating from English first — usually takes six months to a year of consistent input, much of which should be Korean media you actually enjoy. K-dramas, podcasts, and webtoons drill the particle reflex in a way textbooks can't. The plateau between 'I know the rule' and 'I pick the right one without thinking' is where most learners give up. The fix isn't more grammar; it's more time at the input.
