Korean Particles Explained: 은/는, 이/가, 을/를, and More

If you have ever tried reading a Korean sentence and wondered why tiny syllables like 은, 가, or 를 appear after every noun, you have encountered Korean particles. These small but mighty grammatical markers are the glue that holds Korean sentences together. Without them, even a native speaker would struggle to parse meaning from a string of words.

Korean particles — known as 조사 (josa) in Korean — function somewhat like English prepositions, but they come after the noun instead of before it. They tell you whether a noun is the topic, subject, object, location, destination, or something else entirely. Mastering particles is one of the most important steps in learning Korean, and they are tested heavily on every level of the TOPIK exam.

In this guide, you will learn every essential Korean particle from the ground up. We will cover the core markers you need for TOPIK Level 1, work through comparison sections for the trickiest pairs, and provide plenty of example sentences so you can see each particle in action. Whether you are just starting to learn Hangul or preparing for an advanced TOPIK level, this guide has something for you.

How Korean Particles Work: The Consonant and Vowel Rule

Before diving into individual particles, there is one fundamental rule you need to understand. Many Korean particles have two forms: one used after a word ending in a consonant (받침, batchim) and one used after a word ending in a vowel. This exists purely for ease of pronunciation — Korean likes to maintain a smooth flow of sounds.

Here is the pattern at a glance:

• After a consonant (받침): 은, 이, 을, 과, 으로, 이랑
• After a vowel: 는, 가, 를, 와, 로, 랑

For example, the topic marker is 은 after 책 (chaek, "book") because 책 ends in the consonant ㄱ, giving us 책은 (chaekeun). But after 나 (na, "I"), which ends in the vowel ㅏ, we use 는, giving us 나는 (naneun). Once you internalize this rule, choosing the right form becomes automatic.

The Topic Marker: 은/는 (eun/neun)

The topic marker 은/는 is arguably the most fundamental particle in Korean. It marks the topic of the sentence — the thing you are talking about. In English, we often convey the topic through word order or phrases like "as for" or "speaking of."

Use 은 after a consonant and 는 after a vowel:

• 저는 학생이에요 (jeoneun haksaengieyo) — As for me, I am a student
• 한국은 아름다워요 (hangugeun areumdawoyo) — As for Korea, it is beautiful
• 오늘은 날씨가 좋아요 (oneureun nalssiga joayo) — As for today, the weather is good

The topic marker is also used for contrast. When you want to highlight a difference between two things, 은/는 signals that comparison:

• 커피는 좋아해요. 차는 싫어해요. (keopineun joahaeyo. chaneun sireohaeyo.) — I like coffee. As for tea, I dislike it.
• 여름은 더워요. 겨울은 추워요. (yeoreumen deowoyo. gyeoureun chuwoyo.) — Summer is hot. Winter is cold.

The Subject Marker: 이/가 (i/ga)

The subject marker 이/가 identifies who or what performs the action or is being described. Use 이 after a consonant and 가 after a vowel. While the topic marker sets the scene, the subject marker spotlights the actor.

• 비가 와요 (biga wayo) — Rain is coming (it is raining)
• 고양이가 자요 (goyangiga jayo) — The cat is sleeping
• 시간이 없어요 (sigani eopseoyo) — There is no time

이/가 is especially common in the following situations:

• New information: When introducing something for the first time. 남자가 왔어요 (namjaga wasseoyo) — A man came.
• After question words: 누가 했어요? (nuga haesseoyo?) — Who did it?
• Existence and description: 꽃이 예뻐요 (kkochi yeppeoyo) — The flower is pretty.

은/는 vs 이/가: The Great Korean Particle Debate

The distinction between 은/는 and 이/가 is one of the most asked-about topics in Korean grammar. Even intermediate learners sometimes struggle with this. Here is a clear breakdown:

Consider these two sentences:

• 제가 의사예요 (jega uisayeyo) — I am the doctor (emphasizing "I" — answering "who is the doctor?")
• 저는 의사예요 (jeoneun uisayeyo) — As for me, I am a doctor (stating a fact about yourself)

A helpful way to think about it: 은/는 is like a spotlight on the stage — it sets the scene. 이/가 is like a spotlight on a specific actor — it says "this one right here." In practice, most Korean sentences use 은/는 for the main topic and 이/가 for subordinate clauses or new information within that topic.

Understanding this distinction is critical for Korean sentence structure and will be tested repeatedly on the TOPIK exam. Practice by reading Korean texts and identifying why the writer chose 은/는 or 이/가 in each case.

The Object Marker: 을/를 (eul/reul)

The object marker 을/를 identifies the direct object of a verb — the thing being acted upon. Use 을 after a consonant and 를 after a vowel.

• 밥을 먹어요 (babeul meogeoyo) — I eat rice
• 영화를 봐요 (yeonghwareul bwayo) — I watch a movie
• 한국어를 공부해요 (hangugeo-reul gongbuhaeyo) — I study Korean
• 음악을 들어요 (eumageul deureoyo) — I listen to music

In casual spoken Korean, 을/를 is one of the most commonly dropped particles. You will often hear 밥 먹었어? (bap meogeosseo?) instead of the full 밥을 먹었어? (babeul meogeosseo?). However, for the TOPIK exam and formal writing, always include it.

Location Particles: 에 (e) vs 에서 (eseo)

Korean has two location particles that beginners often confuse: 에 and 에서. The difference is straightforward once you understand the underlying logic.

에 (e) — Location of Existence, Destination, and Time

에 marks where something exists, where someone is going, or when something happens:

• Existence: 집에 있어요 (jibe isseoyo) — I am at home
• Destination: 학교에 가요 (hakgyoe gayo) — I go to school
• Time: 세 시에 만나요 (se sie mannayo) — Let's meet at 3 o'clock
• Time: 월요일에 시작해요 (woryoire sijakaeyo) — It starts on Monday

에서 (eseo) — Location of Action and Origin

에서 marks where an action takes place or where something comes from:

• Action location: 도서관에서 공부해요 (doseogwaneseo gongbuhaeyo) — I study at the library
• Action location: 식당에서 먹어요 (sikdangeseo meogeoyo) — I eat at the restaurant
• Origin: 미국에서 왔어요 (migugeseo wasseoyo) — I came from America

Compare these two sentences to see the difference clearly:

• 카페에 있어요 (kapee isseoyo) — I am at the cafe (existence)
• 카페에서 일해요 (kapeeseo ilhaeyo) — I work at the cafe (action)

The verb determines which particle you need. If you are merely existing or arriving somewhere, use 에. If you are doing something there, use 에서.

The Possessive Particle: 의 (ui)

의 (ui, but commonly pronounced "에" in everyday speech) indicates possession or belonging, similar to 's or "of" in English:

• 나의 가방 (naui gabang) — my bag
• 선생님의 이름 (seonsaengnimui ireum) — the teacher's name
• 한국의 역사 (hangugui yeoksa) — the history of Korea
• 우리의 학교 (uriui hakgyo) — our school

In daily conversation, 의 is frequently contracted with pronouns: 나의 → 내 (nae, my), 저의 → 제 (je, my — humble), 너의 → 네 (ne, your — often pronounced 니 to avoid confusion with 내). For the TOPIK exam, recognize both the full and contracted forms.

The "Also" Particle: 도 (do)

도 means "also," "too," or "even." It replaces the topic marker (은/는), subject marker (이/가), or object marker (을/를) — it never stacks on top of them:

• 저는 한국 사람이에요 (jeoneun hanguk saramieyo) — I am Korean → 저도 한국 사람이에요 (jeodo hanguk saramieyo) — I am also Korean
• 커피를 마셔요 (keopireul masyeoyo) — I drink coffee → 차도 마셔요 (chado masyeoyo) — I drink tea too
• 서울에도 가요 (seoure-do gayo) — I also go to Seoul (도 can combine with location particles)

Notice that while 도 replaces 은/는, 이/가, and 을/를, it can be added after other particles like 에, 에서, and 에게. This makes 도 one of the most flexible particles in Korean.

The "And/With" Particles: 와/과, 하고, (이)랑

Korean has several ways to say "and" or "with" when connecting nouns. They all mean roughly the same thing but differ in formality:

• 와/과 (wa/gwa) — Formal/Written: 커피와 차 (keopiwa cha) — coffee and tea. Use 과 after consonants and 와 after vowels.
• 하고 (hago) — Neutral/Spoken: 커피하고 차 (keopi-hago cha) — coffee and tea. No consonant/vowel variation.
• (이)랑 (irang/rang) — Casual/Spoken: 커피랑 차 (keopirang cha) — coffee and tea. Use 이랑 after consonants and 랑 after vowels.

All three can also mean "with":

• 친구와 같이 갔어요 (chinguwa gachi gasseoyo) — I went together with a friend (formal)
• 친구하고 같이 갔어요 (chingu-hago gachi gasseoyo) — I went with a friend (neutral)
• 친구랑 같이 갔어요 (chingurang gachi gasseoyo) — I went with a friend (casual)

For the TOPIK exam, 와/과 appears most frequently because the test uses formal language. In everyday conversation, 하고 and (이)랑 are far more common.

Giving and Telling: 에게/한테/께 (ege/hante/kke)

When you need to indicate a person as the recipient of an action (giving, telling, sending), use these particles:

• 에게 (ege) — Standard/Written: 친구에게 편지를 썼어요 (chinguege pyeonjireul sseosseoyo) — I wrote a letter to a friend
• 한테 (hante) — Casual/Spoken: 친구한테 전화했어요 (chinguhante jeonhwahaesseoyo) — I called a friend
• 께 (kke) — Honorific: 선생님께 여쭤봤어요 (seonsaengnimkke yeojjwobwasseoyo) — I asked the teacher (respectfully)

Important: 에게/한테 are only used for people and animals, not for places or things. For destinations and locations, use 에 instead.

The reverse — receiving from or being affected by someone — uses 에게서 (egeseo) or 한테서 (hanteseo):

• 친구에게서 선물을 받았어요 (chinguegeseo seonmureul badasseoyo) — I received a gift from a friend

Direction and Means: 으로/로 (euro/ro)

으로/로 is one of the most versatile particles in Korean. Use 으로 after consonants (except ㄹ) and 로 after vowels or ㄹ. It covers several meanings:

• Direction: 오른쪽으로 가세요 (oreunjjogeuro gaseyo) — Please go to the right
• Means/Tool: 버스로 가요 (beoseuro gayo) — I go by bus
• Material: 나무로 만들었어요 (namuro mandeureo-sseoyo) — It was made from wood
• Change/Transformation: 의사로 일해요 (uisaro ilhaeyo) — I work as a doctor
• Reason: 감기로 못 갔어요 (gamgiro mot gasseoyo) — I couldn't go because of a cold

Note the special rule: after ㄹ, use 로 (not 으로). For example, 서울로 (seoulo, "to Seoul") not 서울으로, because 울 ends in ㄹ.

Range Particles: 부터/까지 (buteo/kkaji)

부터 means "from" (starting point) and 까지 means "to" or "until" (ending point). They are often used together:

• 월요일부터 금요일까지 일해요 (woryoilbuteo geumyoilkkaji ilhaeyo) — I work from Monday to Friday
• 아침부터 저녁까지 공부했어요 (achimbuteo jeonyeokkkaji gongbuhaesseoyo) — I studied from morning until evening
• 서울에서 부산까지 세 시간 걸려요 (seouleseo busankkaji se sigan geollyeoyo) — It takes three hours from Seoul to Busan
• 1과부터 5과까지 시험이에요 (ilgwabuteo ogwakkaji siheomieyo) — The test covers chapters 1 through 5

까지 can also mean "even" in some contexts: 너까지 그래? (neokkaji geurae?) — Even you are like that?

Limiting Particles: 만 (man) and 밖에 (bakke)

만 means "only" or "just" and can follow any noun or particle:

• 물만 마셔요 (mulman masyeoyo) — I only drink water
• 하나만 주세요 (hanaman juseyo) — Please give me just one
• 주말에만 운동해요 (jumareman undonghaeyo) — I exercise only on weekends

밖에 also means "only" or "nothing but," but it must always be followed by a negative verb:

• 물밖에 없어요 (mulbakke eopseoyo) — There is nothing but water
• 하나밖에 안 남았어요 (hanabakke an namasseoyo) — Only one is left
• 한국어밖에 못 해요 (hangugeobakke mot haeyo) — I can only speak Korean

The difference: 만 is neutral and pairs with positive or negative verbs. 밖에 emphasizes scarcity or limitation and must pair with a negative. Compare: 하나만 있어요 (hanaman isseoyo, "There is only one") versus 하나밖에 없어요 (hanabakke eopseoyo, "There is nothing but one").

Combining Particles: How Korean Stacks Them

One thing that surprises many learners is that Korean particles can be combined. While 은/는, 이/가, and 을/를 generally replace each other, other particles can stack together:

• 에서도 (eseodo) — even at / at ... too: 집에서도 일해요 (jibeseodo ilhaeyo) — I work at home too
• 에서부터 (eseobuteo) — from (a place): 여기에서부터 걸어갔어요 (yeogieseobuteo georeogasseoyo) — I walked from here
• 까지도 (kkajido) — even up to: 밤 12시까지도 공부했어요 (bam yeoldu-sikkajido gongbuhaesseoyo) — I studied even until midnight
• 에게만 (egeman) — only to: 친구에게만 말했어요 (chinguegeman malhaesseoyo) — I told only my friend
• 으로만 (euroman) — only by means of: 지하철로만 다녀요 (jihacheolloman danyeoyo) — I commute only by subway

Understanding particle stacking helps you parse complex sentences that appear at TOPIK Level 3 and above. As your Korean improves, you will start combining particles naturally.

Common Particle Mistakes Korean Learners Make

Here are the most frequent errors and how to avoid them:

1. Confusing 에 and 에서

Remember: 에 is for existence (있다/없다) and destinations (가다/오다). 에서 is for actions happening at a location.

• ✗ 학교에 공부해요 → ✓ 학교에서 공부해요 (hakgyoeseo gongbuhaeyo) — I study at school
• ✗ 집에서 있어요 → ✓ 집에 있어요 (jibe isseoyo) — I am at home

2. Using 은/는 when 이/가 is needed (and vice versa)

After question words like 누구 (nugu, who), 뭐 (mwo, what), and 어디 (eodi, where), always use 이/가 for the answer:

• 누가 했어요? — 제가 했어요. (nuga haesseoyo? — jega haesseoyo.) — Who did it? — I did it.
• ✗ 저는 했어요 (this would mean "As for me, I did it" — different nuance)

3. Stacking 도 on top of 은/는 or 이/가

도 replaces these markers — it does not add onto them:

• ✗ 저는도 → ✓ 저도 (jeodo) — me too
• ✗ 그것이도 → ✓ 그것도 (geugeotdo) — that too

4. Using 에게 for places instead of people

에게/한테 are for people and animals only. For places, use 에:

• ✗ 학교에게 갔어요 → ✓ 학교에 갔어요 (hakgyoe gasseoyo) — I went to school

5. Forgetting the ㄹ exception with 으로/로

After ㄹ, always use 로 (not 으로):

• ✗ 서울으로 → ✓ 서울로 (seoulo) — to Seoul
• ✗ 연필으로 → ✓ 연필로 (yeonpillo) — with a pencil

How to Study Korean Particles Effectively

Particles are best learned in context, not in isolation. Here are proven strategies:

1. Learn particles with full sentences: Instead of memorizing "에 = at," learn 학교에 가요 (hakgyoe gayo, I go to school) as a complete chunk. TOPIKLord's vocabulary cards include example sentences for exactly this reason.
2. Use spaced repetition: Review particle-rich sentences at scientifically optimized intervals. This builds long-term memory far more effectively than cramming.
3. Read Korean texts actively: When reading, pause at each particle and ask yourself why that particular particle was used. This builds intuition over time.
4. Practice minimal pairs: Write the same sentence with different particles and notice how the meaning changes. For example, 학교에 있어요 versus 학교에서 일해요.
5. Master verb conjugation alongside particles: Particles and verb conjugation work hand in hand. Knowing which particles pair with which verb types will accelerate your grammar skills.

Korean Particles by TOPIK Level

Here is a rough guide to which particles you should prioritize based on your target TOPIK level:

TOPIK Level 1-2 (Beginner)

• 은/는 (topic), 이/가 (subject), 을/를 (object)
• 에 (location/time/destination), 에서 (action location)
• 의 (possessive), 도 (also)
• 와/과, 하고 (and/with)
• 에게/한테 (to person), 으로/로 (direction/means)
• 부터/까지 (from/to), 만 (only)

TOPIK Level 3-4 (Intermediate)

• 밖에 (nothing but + negative), 마다 (every)
• (이)나 (or / about / as many as)
• 처럼/같이 (like, similar to)
• 보다 (more than — comparison)
• 대로 (as, according to)
• Particle stacking (에서도, 까지도, etc.)

TOPIK Level 5-6 (Advanced)

• (으)로서 (as, in the capacity of — vs 으로써)
• (으)로써 (by means of — tool or method for abstract actions)
• 에 있어서 (regarding, in terms of)
• 에 의해서 (by — passive agent)
• Subtle 은/는 vs 이/가 distinctions in complex literary contexts

Putting It All Together

Korean particles may seem overwhelming at first, but they follow logical patterns. The consonant/vowel rule governs their forms, their functions map to clear grammatical roles, and with consistent practice they become second nature. Start with the big three — 은/는, 이/가, and 을/를 — then gradually add location particles (에, 에서), connectors (와/과, 하고), and the versatile 으로/로 to your repertoire.

Remember that particles are not just a grammar exercise — they are the key to understanding and being understood in Korean. Every sentence you read, write, or speak is held together by these small but essential markers. The time you invest in mastering them now will pay dividends at every stage of your Korean learning journey, from TOPIK Level 1 all the way to Level 6.
