Mastering Korean Particles: From 은/는 vs 이/가 to 을/를, 에/에서, 도 and 만, with Example Sentences

Many people learning Korean pick up Hangul quickly and memorise basic vocabulary fast. But once they start building sentences, they hit a wall: particles. What's the difference between "저는 학생이에요" and "제가 학생이에요"? Why is it 에 in "학교에 가요" but 에서 in "학교에서 공부해요"?

Particles are small words attached after nouns that show what role the word plays in the sentence. English has nothing quite like them, so they feel hard, but once you understand the logic, Korean sentences start to look much clearer. In this guide we work through the most common particles step by step, with example sentences.

What are particles?

Korean marks the roles of words in a sentence with particles rather than word order. That's why its word order is relatively flexible.

• 민수가 사과를 먹어요. (Minsu = the eater, apple = the thing eaten)
• 사과를 민수가 먹어요. (Same meaning, with slight emphasis on "apple")

The two sentences differ in word order but mean the same thing, because the particles tell you that Minsu, marked with 가, is the one eating and the apple, marked with 를, is what's eaten. That's unlike English, where swapping the order reverses the meaning.

Forms that depend on the final consonant

Many particles change form depending on whether the preceding word ends in a consonant (has a batchim).

Role	After a consonant	After a vowel	Example
Topic	은	는	책은 / 친구는
Subject	이	가	책이 / 친구가
Object	을	를	책을 / 친구를
"And/with"	과	와	책과 / 친구와
Direction/means	으로	로	집으로 / 학교로

The rule exists to make pronunciation smooth: after a consonant, a form beginning with a vowel (은, 이, 을) follows so the sounds link naturally. One exception: 으로/로 uses 로 after a final ㄹ too (e.g. 지하철로 "by subway", 연필로 "with a pencil").

The most confusing pair: 은/는 and 이/가

This is one of the hardest questions for Korean learners. Both look like subjects when translated into English, but their roles differ. The core idea:

• 은/는 marks the topic of the conversation — "as for…". It's used for known information and for contrast.
• 이/가 marks the grammatical subject and is used for new information or to single out a specific thing.

1. Introducing something vs talking about it again

옛날 옛적에 한 소녀가 살았어요. 그 소녀는 아주 착했어요. ("Once upon a time there lived a girl. The girl was very kind.")

The girl appearing for the first time is new information, so she takes 가; when we talk about the now-known girl, she becomes the topic and takes 는.

2. Questions and answers

A: 누가 왔어요? ("Who came?") B: 민수가 왔어요. ("Minsu came.")

When a question word such as 누가 ("who") is the subject, use 이/가, and the answer also attaches 가 to the new information, Minsu. You never say "누는 왔어요?".

3. Contrast

저는 커피는 좋아하지만, 차는 안 좋아해요. ("I like coffee, but I don't like tea.")

은/는 is often used to compare or contrast two things. Saying 커피는 carries the nuance of "coffee, at least, if nothing else".

4. Self-introductions and general facts

저는 학생이에요. ("I'm a student.") 지구는 둥글어요. ("The earth is round.")

In sentences that describe a topic, such as self-introductions and general truths, 은/는 sounds natural.

5. So when do you say "제가 학생이에요"?

When answering "Who's the student?" — emphasising that it's me, out of several people. That's why "제가 학생이에요" sounds odd in an ordinary self-introduction.

6. Expressions that take 이/가

있다/없다 ("to exist/not exist", "to have/not have"), 되다 ("to become"), 아니다 ("to not be") and some expressions of feeling or state often take 이/가.

• 시간이 없어요. ("I don't have time.")
• 저는 의사가 아니에요. ("I'm not a doctor.")
• 저는 고양이가 좋아요. ("I like cats.")
• 머리가 아파요. ("My head hurts.")

As these examples show, 은/는 and 이/가 often appear together in one sentence: "저는 ~가 ~해요". 저는 is the topic ("as for me") and 머리가 is the thing that hurts.

The object marker 을/를

Marks the target of an action — the object.

• 밥을 먹어요. ("I eat a meal.")
• 영화를 봐요. ("I watch a film.")
• 한국어를 공부해요. ("I study Korean.")

Watch out: 좋아하다 ("to like") takes 을/를, but 좋다 ("to be good/liked") takes 이/가. "저는 고양이를 좋아해요" and "저는 고양이가 좋아요" mean much the same but use different particles. Some verbs also take particles you might not expect from English: 만나다 ("to meet") and 타다 ("to ride") take 을/를, as in 친구를 만나요 and 버스를 타요.

Places: 에 and 에서

Both attach to places but are used differently.

Particle	Use	Example
에	Location of existence (있다/없다)	책상 위에 책이 있어요. ("There's a book on the desk.")
에	Destination (가다/오다)	학교에 가요. ("I go to school.")
에	Time	세 시에 만나요. ("Let's meet at three.")
에서	Place where an action happens	도서관에서 공부해요. ("I study at the library.")
에서	Starting point ("from")	서울에서 왔어요. ("I came from Seoul.")

A simple rule of thumb: with verbs like 있다, 없다, 가다 and 오다, use 에; for an action you do at a place, use 에서.

• 카페에 가요. ("I go to a café" — destination)
• 카페에서 커피를 마셔요. ("I drink coffee at a café" — place of action)

To people: 에게, 한테, 께

Used when giving something to, or speaking to, a person or animal. 에게 appears in writing and formal speech, 한테 in everyday conversation, and 께 is the honorific form for elders.

• 친구에게 편지를 써요. ("I write a letter to a friend.")
• 동생한테 전화했어요. ("I called my younger sibling.")
• 할머니께 선물을 드렸어요. ("I gave a present to my grandmother.")

For things and places, use 에 — e.g. 회사에 전화했어요 ("I called the office").

Possession: 의

의 is similar to "of" or the possessive "'s". It's usually pronounced [에].

• 친구의 책 ("a friend's book")
• 한국의 수도 ("the capital of Korea")

In everyday speech 의 is often dropped: 친구 책, 우리 엄마 ("my mum") sound perfectly natural. 나의, 너의 and 저의 shorten to 내, 네 and 제.

도 and 만

도: "also, too"

저도 학생이에요. ("I'm a student too.") 사과도 사고 배도 샀어요. ("I bought apples and pears too.")

도 replaces 은/는, 이/가 or 을/를 rather than being added to them. You don't say "저는도" or "사과를도".

만: "only"

저는 물만 마셔요. ("I only drink water.") 한 번만 도와주세요. ("Please help me just once.")

Other particles can follow 만, as in 너만을 사랑해 ("I love only you").

"And/with": 와/과, 하고, (이)랑

These connect two nouns or mean "together with". The meaning is the same, but the register differs.

Particle	Register	Example
와/과	Writing, formal	빵과 우유를 샀다.
하고	Everyday speech	빵하고 우유를 샀어요.
(이)랑	Casual speech	빵이랑 우유 샀어.

(All three mean "I bought bread and milk.")

Direction and means: 으로/로

• Direction: 오른쪽으로 가세요. ("Go to the right.") 부산으로 떠나요. ("I'm leaving for Busan.")
• Means/tool: 지하철로 가요. ("I go by subway.") 젓가락으로 먹어요. ("I eat with chopsticks.")
• Material: 쌀로 떡을 만들어요. ("Rice cakes are made from rice.")
• Change: 물이 얼음으로 변했어요. ("The water turned into ice.")

Range: 부터 and 까지

아홉 시부터 여섯 시까지 일해요. ("I work from nine to six.") 서울에서 부산까지 기차로 가요. ("I go from Seoul to Busan by train.")

For the start of a time, use 부터; for a starting place, usually 에서; for the end of either, 까지.

Dropping particles in speech

In real Korean conversation, particles are often dropped — especially 은/는, 이/가 and 을/를 when the meaning is clear from context.

• 너 밥 먹었어? (너는 밥을 먹었어? "Have you eaten?")
• 나 이거 좋아. (나는 이것이 좋아. "I like this.")

That's why you often can't hear particles in dramas. Early on, though, it's best to practise putting them in correctly; you'll pick up dropping them naturally once you understand the logic. Particles that change meaning — 에, 에서, 에게, 도, 만 — are not dropped.

Common mistakes

Incorrect	Correct	Why
학교에서 가요.	학교에 가요.	Destinations take 에
도서관에 공부해요.	도서관에서 공부해요.	Places of action take 에서
누는 왔어요?	누가 왔어요?	Question-word subjects take 이/가
저는도 가요.	저도 가요.	도 replaces 는
친구에 전화했어요.	친구한테 전화했어요.	People take 에게/한테
책이 읽어요.	책을 읽어요.	The object of an action takes 을/를

How to absorb particles naturally

• Memorise whole sentences: rather than learning particles in isolation, memorise chunks such as 학교에 가요 and 도서관에서 공부해요.
• Transcribe drama lines: write out the dialogue from short scenes and mark the particles. You'll see how they're really used and when they're dropped.
• Write sentences about yourself: write a few sentences every day such as "저는 ~예요", "저는 ~를 좋아해요" and "저는 ~에서 일해요".
• Mistakes are fine: even with the wrong particle, your meaning usually gets across. Speaking a lot without fear is the fastest way to improve.

Final thoughts

Particles feel like small obstacles at first, but once you're used to them they become a powerful tool for expressing the subtle nuances of Korean. If you've started to sense the difference between 커피는 좋아해요 and 커피를 좋아해요, your Korean has already moved up a level.

Try writing five sentences about yourself using today's particles. Small particles, one by one, add up to natural Korean.
