## Korean Particle Guide: 은/는, 이/가, 을/를 [PDF]

Korean particles are those tiny words attached to nouns that make English speakers want to throw their textbook across the room. 은/는, 이/가, 을/를—they look similar, they seem interchangeable, and every time you think you've figured them out, a new sentence proves you wrong.

But here's the truth: Korean particles aren't random. They follow clear patterns, and once you understand what each one does, Korean sentences suddenly start making sense in a way they didn't before.

This guide covers the three most important particles—the ones you'll use in literally every Korean conversation. And yes, there's a downloadable PDF at the end so you can keep this as a quick reference.

### Why Particles Matter

In English, word order tells you who does what:

- "The dog chased the cat." (dog = chaser, cat = chased)

- "The cat chased the dog." (cat = chaser, dog = chased)

In Korean, **particles** do that job instead. Word order is flexible, so the particle attached to each noun is what tells you its role in the sentence.

- 개가 고양이를 쫓았어요. (The dog chased the cat.)

- 고양이를 개가 쫓았어요. (The dog chased the cat.) ← Same meaning, different order!

Without particles, Korean sentences would be a guessing game. With them, every noun's role is crystal clear.

### Particle 1: 은/는 — The Topic Marker

**Use 은 after a consonant, 는 after a vowel.**

은/는 marks the **topic** of your sentence—what you're talking about. Think of it as shining a spotlight: "Hey everyone, I'm talking about THIS."

| Example | Pronunciation | Meaning |
| --- | --- | --- |
| 저**는** 학생이에요. | jeo**neun** haksaengieyo | As for me, I'm a student. |
| 한국 음식**은** 맛있어요. | hanguk eumsig**eun** masisseoyo | As for Korean food, it's delicious. |
| 오늘**은** 바빠요. | oneul**eun** bappayo | As for today, I'm busy. |
| 이 책**은** 재미있어요. | i chaeg**eun** jaemiisseoyo | As for this book, it's interesting. |

**When to use it:**

**1. Introducing a topic for the first time:**
When you start a new subject in conversation.

- 저**는** 미국에서 왔어요. (As for me, I came from America.)

**2. Comparing or contrasting:**
This is 은/는's superpower. It implies "this one, as opposed to that one."

- 커피**는** 좋아해요. 차**는** 별로예요. (Coffee, I like. Tea, not so much.)

- 어제**는** 비가 왔어요. 오늘**은** 맑아요. (Yesterday it rained. Today it's clear.)

**3. Making general statements:**

- 건강**은** 중요해요. (Health is important.)

- 시간**은** 금이에요. (Time is gold.)

**Real moment:** At a Korean BBQ dinner, your friend asks what everyone wants to order. One person says "저는 삼겹살이요" (as for me, samgyeopsal). Another says "저는 갈비요" (as for me, galbi). That 는 naturally creates a contrast between each person's choice. It's elegant, and it's exactly how Koreans actually talk in this situation.

### Particle 2: 이/가 — The Subject Marker

**Use 이 after a consonant, 가 after a vowel.**

이/가 marks the **subject**—who or what is doing the action or being described. It's especially used for new information, answers to questions, and observations.

| Example | Pronunciation | Meaning |
| --- | --- | --- |
| 비**가** 와요. | bi**ga** wayo | It's raining. (Rain is coming.) |
| 친구**가** 왔어요. | chingu**ga** wasseoyo | A friend came. |
| 시간**이** 없어요. | sigan**i** eopseoyo | There's no time. |
| 뭐**가** 맛있어요? | mwo**ga** masisseoyo? | What's delicious? |

**When to use it:**

**1. Answering "who" or "what" questions:**
When someone asks who did something, your answer identifies the subject.

- 👩 "누가 전화했어요?" (Who called?)

- 👨 "제**가** 전화했어요." (I called.) — I'm the one.

**2. Introducing new information:**
When something appears for the first time—a fresh observation.

- 눈**이** 와요! (It's snowing! — you just noticed)

- 고양이**가** 있어요! (There's a cat! — you just spotted it)

**3. With 있다/없다 (existence verbs):**

- 돈**이** 있어요? (Do you have money?)

- 문제**가** 없어요. (There's no problem.)

### 은/는 vs 이/가: The Real Difference

This is the question that haunts every Korean learner. Here's the clearest way I can explain it:

**은/는** says: "Speaking of X..." (sets the frame, may imply contrast)
**이/가** says: "X is the one that..." (identifies the specific subject)

| Situation | Use | Example |
| --- | --- | --- |
| Introducing yourself | 은/는 | 저**는** 사라예요. (I'm Sarah.) |
| Answering "who?" | 이/가 | 제**가** 했어요. (I did it.) |
| Fresh observation | 이/가 | 비**가** 와요! (It's raining!) |
| Contrasting | 은/는 | 나**는** 좋아. 너**는**? (I like it. You?) |
| With 있다/없다 | 이/가 | 시간**이** 있어요? (Have time?) |
| General statements | 은/는 | 건강**은** 중요해요. (Health is important.) |

**The same sentence, two meanings:**

저**는**학생이에요. → "As for me, I'm a student." (Introducing yourself)

제

**가** 학생이에요. → "I'M the student." (Answering who the student is)

날씨**는**좋아요. → "The weather is nice." (Topic: weather. Maybe implies something else isn't nice.)

날씨

**가** 좋아요. → "The weather is nice!" (Simple observation.)

### Particle 3: 을/를 — The Object Marker

**Use 을 after a consonant, 를 after a vowel.**

을/를 marks the **object**—what receives the action. If someone eats something, the something gets 을/를.

| Example | Pronunciation | Meaning |
| --- | --- | --- |
| 밥**을** 먹어요. | bab**eul** meogeoyo | I eat rice. |
| 커피**를** 마셔요. | keopi**reul** masyeoyo | I drink coffee. |
| 영화**를** 봐요. | yeonghwa**reul** bwayo | I watch a movie. |
| 한국어**를** 공부해요. | hangugeo**reul** gongbuhaeyo | I study Korean. |

This one is more straightforward than 은/는 and 이/가. If there's an action verb and something receives that action, it gets 을/를.

**In conversation:**

- 👩 "점심에 뭐 먹었어요?" (What did you eat for lunch?)

- 👨 "비빔밥**을** 먹었어요." (I ate bibimbap.)

- 👩 "음료**는**요?" (What about a drink?) ← Notice 는 here for "as for drinks?"

- 👨 "커피**를** 마셨어요." (I drank coffee.)

### All Three in One Sentence

Let's see how they work together:

**저는 한국어를 공부해요.**
(jeoneun hangugeoreul gongbuhaeyo)

- 저**는** = As for me (topic)

- 한국어**를** = Korean (object—thing being studied)

- 공부해요 = study

**친구가 김치를 만들었어요.**
(chinguga gimchireul mandeureoesseoyo)

- 친구**가** = A friend (subject—the one who made it)

- 김치**를** = kimchi (object—the thing made)

- 만들었어요 = made

**Real moment:** When I teach particles, I use a restaurant metaphor. The topic marker (은/는) is like saying "at THIS restaurant..." The subject marker (이/가) is like saying "THIS dish is the one that..." The object marker (을/를) is "I'll have THIS." Each one has a clear job, and they often appear in the same sentence without confusion.

### When Koreans Drop Particles

Here's a secret that textbooks won't tell you: in casual spoken Korean, particles get dropped constantly.

- "밥 먹었어?" instead of "밥을 먹었어?" (Did you eat?)

- "나 학생이야" instead of "나는 학생이야" (I'm a student.)

- "커피 마실래?" instead of "커피를 마실래?" (Want coffee?)

In relaxed speech, if the meaning is clear from context, particles are optional. But in these situations, you should use them:

- Writing (essays, messages, formal texts)

- Tests (TOPIK, school exams)

- Polite/formal speech

- When clarity matters (the meaning would be ambiguous without them)

### Beyond the Big Three

Once you master 은/는, 이/가, and 을/를, you'll encounter more particles:

| Particle | Function | Example |
| --- | --- | --- |
| 에 | Location (at, to) / time (at) | 학교**에** 가요. (Going to school.) |
| 에서 | Location (at, in) for actions | 카페**에서** 공부해요. (Studying at a café.) |
| (으)로 | Direction / means | 버스**로** 가요. (Going by bus.) |
| 와/과, 하고 | And, with | 친구**하고** 같이 (With a friend) |
| 도 | Also, too | 저**도** 가요. (I'm going too.) |
| 만 | Only | 물**만** 주세요. (Just water please.) |

These are covered in the full PDF guide below.
