If you’ve been learning Korean for a while, you’ve probably noticed four small words that appear everywhere: 은, 는, 이, and 가.
These are among the most important Korean particles, but they can also be confusing.
Why do Korean speakers sometimes say:
저는 학생이에요.
“I am a student.”
🔊 Listen: 저는 학생이에요.
But in another situation say:
제가 학생이에요.
“I’m the student.” / “I am the one who is a student.”
🔊 Listen: 제가 학생이에요.
Both sentences are grammatically correct. They can even describe the same person, but they don’t always communicate the same information.
The difference involves how Korean speakers organize conversations, introduce information, identify people, and express contrast.
In this complete guide to Korean particles 은/는 vs 이/가, you’ll learn the basic rules, understand when each particle sounds natural, compare similar sentences, and practice with everyday conversations and listening exercises.
Level: Beginner–Lower Intermediate (A1–A2)
Study time: Approximately 20–30 minutes
What you’ll learn: Topic markers, subject markers, consonant and vowel rules, information focus, contrast, common mistakes, pronunciation, and real-life usage.
How to study: Read the paired examples, listen to each Korean sentence separately, and consider the situation before choosing a particle. Do not memorize a single English translation for each particle.

1. What Are Korean Particles?
Korean particles are short grammatical elements attached to words to show their roles or relationships within a sentence.
Unlike English, Korean often marks grammatical and conversational information directly after nouns.
For example:
저는 한국어를 공부해요.
“I study Korean.”
🔊 Listen: 저는 한국어를 공부해요.
Let’s break down the sentence.
| Korean | Function | English |
|---|---|---|
| 저 | Pronoun | I / me (humble) |
| 는 | Topic marker | Marks what the sentence is about |
| 한국어 | Noun | Korean language |
| 를 | Object marker | Marks the object of studying |
| 공부해요 | Verb | Study |
The topic marker 는 tells the listener that the speaker is talking about themselves.
Why Particles Matter
Consider these sentences:
저는 학생이에요.
“I am a student.”
제가 학생이에요.
“I’m the student.”
Without context, their English translations can look almost identical.
But Korean particles give additional information about what is being discussed and what is being identified.
You can think of it this way:
- 은/는: “As for…” or “Speaking of…”
- 이/가: Often identifies the subject or highlights who or what a statement concerns
These are helpful learning shortcuts, not exact translations that work in every sentence.
The Basic Difference
| 은/는 | 이/가 |
|---|---|
| Topic markers | Subject markers |
| Establish or maintain a topic | Mark a grammatical subject |
| Often used for comparison or contrast | Often identify a specific person or thing |
| Frequently appear with familiar topics | Frequently appear in answers introducing focused information |
| Can mark topics that aren’t grammatical subjects | Mark subjects within clauses |
Important: Topic and subject are different grammatical functions. They are not simply two ways to express English “I” or “the.”
2. How to Use 은 and 는: Korean Topic Particles
The particles 은 and 는 are topic markers.
They tell the listener what the speaker wants to talk about.
The choice between 은 and 는 depends on the final sound of the preceding word.
Rule 1: Consonant-Ending Nouns + 은
If the word ends in a consonant (받침), attach 은.
| Noun | With particle | Meaning |
|---|---|---|
| 학생 | 학생은 | As for the student |
| 책 | 책은 | As for the book |
| 한국 | 한국은 | As for Korea |
| 오늘 | 오늘은 | As for today |
| 이름 | 이름은 | As for the name |
| 물 | 물은 | As for water |
Listen to these examples.
🔊 Listen: 학생은
🔊 Listen: 책은
🔊 Listen: 한국은
🔊 Listen: 오늘은
🔊 Listen: 이름은
🔊 Listen: 물은
Rule 2: Vowel-Ending Nouns + 는
If the word ends in a vowel, attach 는.
| Noun | With particle | Meaning |
|---|---|---|
| 저 | 저는 | As for me |
| 나 | 나는 | As for me (casual) |
| 친구 | 친구는 | As for my friend |
| 학교 | 학교는 | As for the school |
| 커피 | 커피는 | As for coffee |
| 사과 | 사과는 | As for apples |
Practice each expression.
🔊 Listen: 저는
🔊 Listen: 나는
🔊 Listen: 친구는
🔊 Listen: 학교는
🔊 Listen: 커피는
🔊 Listen: 사과는
Making Complete Sentences with 은/는
저는 한국 사람이에요.
“I’m Korean.”
🔊 Listen: 저는 한국 사람이에요.
제 친구는 대학생이에요.
“My friend is a university student.”
🔊 Listen: 제 친구는 대학생이에요.
이 책은 재미있어요.
“This book is interesting.”
🔊 Listen: 이 책은 재미있어요.
오늘은 날씨가 좋아요.
“The weather is nice today.”
🔊 Listen: 오늘은 날씨가 좋아요.
The topic may be a person, object, place, day, or something else relevant to the conversation.
Think of 은/는 as a Conversation Signpost
Imagine beginning a conversation about your family.
우리 아버지는 선생님이에요.
“My father is a teacher.”
🔊 Listen: 우리 아버지는 선생님이에요.
You’ve established your father as the topic.
You can then continue talking about him without repeating the topic in every sentence.
학교에서 일하세요.
“He works at a school.”
🔊 Listen: 학교에서 일하세요.
Korean frequently omits information that is already clear from context.
This is one reason learning topic markers is so useful.
3. How to Use 이 and 가: Korean Subject Particles
The particles 이 and 가 mark grammatical subjects.
They are particularly useful when identifying who did something, what exists, or what has a particular quality.
Rule 1: Consonant-Ending Nouns + 이
| Noun | With particle | English |
|---|---|---|
| 학생 | 학생이 | Student (subject) |
| 책 | 책이 | Book (subject) |
| 사람 | 사람이 | Person (subject) |
| 물 | 물이 | Water (subject) |
| 이름 | 이름이 | Name (subject) |
| 집 | 집이 | House (subject) |
Listen and repeat.
🔊 Listen: 학생이
🔊 Listen: 책이
🔊 Listen: 사람이
🔊 Listen: 물이
🔊 Listen: 이름이
🔊 Listen: 집이
Rule 2: Vowel-Ending Nouns + 가
| Noun | With particle | English |
|---|---|---|
| 친구 | 친구가 | Friend (subject) |
| 고양이 | 고양이가 | Cat (subject) |
| 커피 | 커피가 | Coffee (subject) |
| 사과 | 사과가 | Apple (subject) |
| 학교 | 학교가 | School (subject) |
| 날씨 | 날씨가 | Weather (subject) |
Listen to the correct combinations.
🔊 Listen: 친구가
🔊 Listen: 고양이가
🔊 Listen: 커피가
🔊 Listen: 사과가
🔊 Listen: 학교가
🔊 Listen: 날씨가
Important Exception: 저 → 제가, 나 → 내가
Two extremely common pronouns have special forms with 가.
| Basic pronoun | With topic marker | With subject marker |
|---|---|---|
| 저 (polite/humble I) | 저는 | 제가 |
| 나 (casual I) | 나는 | 내가 |
Do not write 저가 or 나가 when you mean “I” with the subject particle.
Practice the forms.
🔊 Listen: 저는
🔊 Listen: 제가
🔊 Listen: 나는
🔊 Listen: 내가
Complete Sentences with 이/가
비가 와요.
“It’s raining.”
🔊 Listen: 비가 와요.
고양이가 자요.
“The cat is sleeping.”
🔊 Listen: 고양이가 자요.
친구가 왔어요.
“My friend came.”
🔊 Listen: 친구가 왔어요.
책이 있어요.
“There’s a book.”
🔊 Listen: 책이 있어요.
날씨가 추워요.
“The weather is cold.”
🔊 Listen: 날씨가 추워요.
These sentences describe something about their subjects. Depending on the context, 이/가 can also help identify or focus attention on the subject.
4. 은/는 vs 이/가: The Most Important Difference
You’ve learned how to attach the particles. Now comes the part that often takes longer to master: choosing the right particle for the situation.
There is no perfect one-line English translation that explains every use.
However, three practical distinctions will help you understand most beginner conversations.
Difference 1: Talking About a Topic vs. Identifying a Subject
Compare these two sentences.
저는 학생이에요.
“I am a student.”
🔊 Listen: 저는 학생이에요.
제가 학생이에요.
“I’m the student.”
🔊 Listen: 제가 학생이에요.
The first sentence makes “me” the topic of the conversation.
It’s a natural way to introduce yourself.
The second can identify the speaker as the particular person who is a student.
For example, imagine a teacher asks which person in a group is the student.
누가 학생이에요?
“Who is the student?”
🔊 Listen: 누가 학생이에요?
A natural answer is:
제가 학생이에요.
“I’m the student.”
🔊 Listen: 제가 학생이에요.
The particle 가 helps identify the answer to “who?”
Remember: This is a tendency based on conversational context. 제가 학생이에요 is not restricted to answering that exact question, and 저는 학생이에요 is not restricted to self-introductions.
Difference 2: Familiar Topics vs. Newly Introduced Information
Consider a short story.
어제 친구가 왔어요.
“My friend came yesterday.”
🔊 Listen: 어제 친구가 왔어요.
The speaker introduces their friend as part of the event.
Then the speaker continues:
그 친구는 미국 사람이에요.
“That friend is American.”
🔊 Listen: 그 친구는 미국 사람이에요.
Now the friend has become the topic of the conversation.
The pattern is:
Introduce information → Continue talking about it
You may often see 이/가 in the introduction and 은/는 in later statements.
But this is not an absolute rule. Topic markers can introduce topics, and subject markers can appear with familiar information too.
Difference 3: Neutral Description vs. Contrast
Compare these sentences.
커피가 맛있어요.
“The coffee is delicious.”
🔊 Listen: 커피가 맛있어요.
커피는 맛있어요.
“The coffee is good, though.” / “As for the coffee, it’s delicious.”
🔊 Listen: 커피는 맛있어요.
The first sentence can be a straightforward description.
The second may establish coffee as a topic or contrast it with something else.
For example:
음식은 별로예요. 그런데 커피는 맛있어요.
“The food isn’t very good. But the coffee is delicious.”
🔊 Listen: 음식은 별로예요. 그런데 커피는 맛있어요.
Here, 는 clearly helps create a contrast.
The same particle can have a neutral topic meaning in another context. You should not automatically translate every 는 as “but.”
5. Listening Comparison: 저는 vs 제가
This is one of the most useful listening exercises for understanding Korean particles.
Read the situation first, then listen to each sentence.
Pair 1: Introducing Yourself
저는 민수예요.
“I’m Minsu.”
🔊 Listen: 저는 민수예요.
제가 민수예요.
“I’m Minsu.” / “I’m the one named Minsu.”
🔊 Listen: 제가 민수예요.
The first is a natural general introduction.
The second is useful when identifying yourself as the person someone is looking for.
For example:
민수 씨가 누구예요?
“Who is Minsu?”
🔊 Listen: 민수 씨가 누구예요?
제가 민수예요.
“I’m Minsu.”
Pair 2: Talking About Work
저는 여기서 일해요.
“I work here.”
🔊 Listen: 저는 여기서 일해요.
제가 여기서 일해요.
“I’m the one who works here.”
🔊 Listen: 제가 여기서 일해요.
The second version may emphasize or identify the person doing the work.
Pair 3: Taking Responsibility
저는 할게요.
“I’ll do it.”
🔊 Listen: 저는 할게요.
제가 할게요.
“I’ll do it.” / “Let me do it.”
🔊 Listen: 제가 할게요.
Both are grammatical. In many situations where you volunteer to take responsibility, 제가 할게요 sounds especially natural.
Pair 4: Talking About Preferences
저는 커피를 좋아해요.
“I like coffee.”
🔊 Listen: 저는 커피를 좋아해요.
제가 커피를 좋아해요.
“I’m the one who likes coffee.”
🔊 Listen: 제가 커피를 좋아해요.
The second can be used when identifying the person who likes coffee.
It is not the default choice for an ordinary statement about your preferences.
What to Listen For
The particles are not necessarily distinguished by a special pronunciation in these sentences. The important differences are grammatical and contextual.
Listen to the complete sentences and imagine why someone would say them.
Your goal: Learn to associate each sentence with a realistic situation, not simply memorize a translated definition.
6. Korean Topic Markers for Contrast: 은/는
Contrast is one of the most important functions of 은/는.
You can use these particles to compare people, objects, activities, or situations.
Comparing Two People
저는 학생이에요. 제 친구는 회사원이에요.
“I’m a student. My friend is an office worker.”
🔊 Listen: 저는 학생이에요.
🔊 Listen: 제 친구는 회사원이에요.
The topic markers help establish the two people being discussed.
Comparing Two Foods
사과는 좋아해요. 그런데 바나나는 안 좋아해요.
“I like apples, but I don’t like bananas.”
🔊 Listen: 사과는 좋아해요.
🔊 Listen: 그런데 바나나는 안 좋아해요.
Notice how the two foods are contrasted.
Comparing Two Days
오늘은 바빠요. 내일은 괜찮아요.
“I’m busy today. Tomorrow is fine.”
🔊 Listen: 오늘은 바빠요.
🔊 Listen: 내일은 괜찮아요.
This is a natural use of the topic marker when discussing different days.
Comparing Two Languages
한국어는 재미있어요. 하지만 발음은 어려워요.
“Korean is interesting, but the pronunciation is difficult.”
🔊 Listen: 한국어는 재미있어요.
🔊 Listen: 하지만 발음은 어려워요.
Here, the speaker contrasts their evaluation of Korean in general with the difficulty of pronunciation.
Does 는 Always Mean Contrast?
No.
저는 학생이에요 can simply introduce the speaker as a topic.
커피는 맛있어요 can either make coffee the topic or imply contrast, depending on the surrounding conversation.
Learning principle: A particle’s meaning becomes clearer when you look at the sentence before it and the sentence after it.
7. Choosing Particles in Korean Question-and-Answer Conversations
Questions are an excellent way to understand the difference between topic and subject markers.
Instead of studying isolated sentences, focus on what the conversation is asking.
Conversation 1: Who Came?
A: 누가 왔어요?
“Who came?”
🔊 Listen: 누가 왔어요?
B: 민수가 왔어요.
“Minsu came.”
🔊 Listen: 민수가 왔어요.
The question asks for the identity of the person who came.
The answer provides that person using 가.
Now imagine a different conversation:
A: 민수는 왔어요?
“Did Minsu come?”
🔊 Listen: 민수는 왔어요?
B: 네, 민수는 왔어요.
“Yes, Minsu came.”
🔊 Listen: 네, 민수는 왔어요.
Minsu is already the person under discussion, and 는 can also suggest a contrast with other people.
Conversation 2: Who Is the Teacher?
A: 누가 선생님이에요?
“Who is the teacher?”
🔊 Listen: 누가 선생님이에요?
B: 저분이 선생님이에요.
“That person is the teacher.”
🔊 Listen: 저분이 선생님이에요.
The answer identifies the teacher.
Now compare:
A: 저분은 누구예요?
“Who is that person?”
🔊 Listen: 저분은 누구예요?
B: 저분은 선생님이에요.
“That person is a teacher.”
🔊 Listen: 저분은 선생님이에요.
Both conversations refer to a teacher, but they organize the information differently.
Conversation 3: Talking About Your Family
A: 가족은 어디에 살아요?
“Where does your family live?”
🔊 Listen: 가족은 어디에 살아요?
B: 가족은 부산에 살아요.
“My family lives in Busan.”
🔊 Listen: 가족은 부산에 살아요.
The conversation has already established “family” as its topic.
Conversation 4: Finding an Object
A: 열쇠가 어디 있어요?
“Where is the key?”
🔊 Listen: 열쇠가 어디 있어요?
B: 열쇠는 책상 위에 있어요.
“The key is on the desk.”
🔊 Listen: 열쇠는 책상 위에 있어요.
This shows an important point: a question may contain 가 and its answer may use 는.
The topic of the answer and the grammatical subject of the question do not have to use identical particles.
8. Korean Particles with 있다/없다 and Descriptive Verbs
Many beginner sentences use 이/가 with existence expressions and descriptive predicates.
Understanding this will help you recognize patterns in ordinary Korean conversations.
Using 이/가 with 있어요 and 없어요
책이 있어요.
“There is a book.”
🔊 Listen: 책이 있어요.
시간이 없어요.
“I don’t have time.”
🔊 Listen: 시간이 없어요.
고양이가 있어요.
“There is a cat.” / “I have a cat.”
🔊 Listen: 고양이가 있어요.
These are straightforward statements involving existence or availability.
But 은/는 is possible when establishing or contrasting a topic.
Compare:
시간이 있어요.
“I have time.”
🔊 Listen: 시간이 있어요.
시간은 있어요.
“I do have time.” / “As for time, I have some.”
🔊 Listen: 시간은 있어요.
The second may suggest that time is available, even if something else isn’t.
Using 이/가 with Descriptions
날씨가 좋아요.
“The weather is nice.”
🔊 Listen: 날씨가 좋아요.
음식이 맛있어요.
“The food is delicious.”
🔊 Listen: 음식이 맛있어요.
한국어가 재미있어요.
“Korean is interesting.”
🔊 Listen: 한국어가 재미있어요.
These statements are common in everyday Korean.
Now compare:
오늘은 날씨가 좋아요.
“The weather is nice today.”
🔊 Listen: 오늘은 날씨가 좋아요.
Here, 오늘은 is the topic, while 날씨가 marks the grammatical subject of the description.
One sentence can contain both a topic marker and a subject marker.
This is essential for understanding more complex Korean sentences.
To explore this structure further, read our related beginner lesson:
Learn Korean Grammar: 있어요 and 없어요
9. Can 은/는 and 이/가 Appear in the Same Sentence?
Yes. This is a very important feature of Korean sentence structure.
A topic does not have to be the grammatical subject.
Consider the following sentence:
저는 한국어가 재미있어요.
“As for me, Korean is interesting.” / “I find Korean interesting.”
🔊 Listen: 저는 한국어가 재미있어요.
Let’s break it down.
| Part | Function |
|---|---|
| 저 | Me / I |
| 는 | Topic marker |
| 한국어 | Korean language |
| 가 | Subject marker |
| 재미있어요 | Is interesting |
The topic is the speaker.
The subject of the description is the Korean language.
Another Example: Family
저는 동생이 있어요.
“I have a younger sibling.”
🔊 Listen: 저는 동생이 있어요.
This sentence contains:
- 저는 — “As for me”
- 동생이 — “A younger sibling” as the subject of 있어요
- 있어요 — “Exists / have”
The sentence expresses possession in a natural Korean structure.
Another Example: My Friend
제 친구는 키가 커요.
“My friend is tall.”
🔊 Listen: 제 친구는 키가 커요.
Literally, you can think of it as:
“As for my friend, their height is big.”
You don’t need to translate it this way in natural English, but the underlying structure explains why both 는 and 가 appear.
Another Example: The Restaurant
이 식당은 음식이 맛있어요.
“The food at this restaurant is delicious.”
🔊 Listen: 이 식당은 음식이 맛있어요.
Here:
- 이 식당은 establishes the restaurant as the topic.
- 음식이 is the subject of 맛있어요.
Key takeaway: Do not assume that every Korean sentence must contain only one of these particles. 은/는 and 이/가 can serve different functions in the same sentence.
10. Do Korean Speakers Always Use These Particles?
No. In everyday speech, Korean speakers frequently omit particles when the context is clear.
This is especially common in short questions and casual conversations.
Complete vs. Conversational Sentences
시간이 있어요?
“Do you have time?”
🔊 Listen: 시간이 있어요?
시간 있어요?
“Do you have time?”
🔊 Listen: 시간 있어요?
Both are natural.
Similarly:
커피가 있어요?
“Is there coffee?”
🔊 Listen: 커피가 있어요?
커피 있어요?
“Is there coffee?”
🔊 Listen: 커피 있어요?
The shorter versions are common in conversations.
Does That Mean Particles Are Optional Everywhere?
No.
Some omissions sound natural, while others may change the structure, emphasis, or clarity of a sentence.
Formal writing also tends to preserve grammatical marking more consistently than casual speech.
Beginner advice: Learn to build complete sentences first. Once you’re comfortable with the grammar, pay attention to how native speakers shorten expressions in real conversations.
11. Real-Life Korean Conversations with 은/는 and 이/가
Let’s bring the grammar together with natural dialogues.
Conversation 1: First Meeting
A: 안녕하세요. 저는 엠마예요.
“Hello. I’m Emma.”
🔊 Listen: 안녕하세요. 저는 엠마예요.
B: 안녕하세요. 저는 민수예요.
“Hello. I’m Minsu.”
🔊 Listen: 안녕하세요. 저는 민수예요.
A: 민수 씨는 학생이에요?
“Minsu, are you a student?”
🔊 Listen: 민수 씨는 학생이에요?
B: 아니요, 저는 회사원이에요.
“No, I’m an office worker.”
🔊 Listen: 아니요, 저는 회사원이에요.
Here, 는 is natural because the speakers are introducing themselves and asking about the other person’s background.
If you want more practice introducing yourself, use this lesson:

Conversation 2: At a Café
A: 이 카페는 커피가 맛있어요.
“The coffee at this café is delicious.”
🔊 Listen: 이 카페는 커피가 맛있어요.
B: 맞아요. 케이크도 맛있어요.
“That’s right. The cake is delicious too.”
🔊 Listen: 맞아요. 케이크도 맛있어요.
A: 그런데 가격은 조금 비싸요.
“But the prices are a little high.”
🔊 Listen: 그런데 가격은 조금 비싸요.
The first sentence uses topic and subject markers together. The final sentence uses 은 to contrast the price with the positive comments.
Conversation 3: Finding the Person Responsible
A: 누가 이 일을 할 거예요?
“Who will do this job?”
🔊 Listen: 누가 이 일을 할 거예요?
B: 제가 할게요.
“I’ll do it.”
🔊 Listen: 제가 할게요.
A: 정말요? 감사합니다.
“Really? Thank you.”
🔊 Listen: 정말요? 감사합니다.
This is an especially practical use of 제가.
The speaker volunteers as the person who will perform the action.
Conversation 4: Comparing Schedules
A: 오늘은 시간 있어요?
“Do you have time today?”
🔊 Listen: 오늘은 시간 있어요?
B: 오늘은 바빠요. 그런데 내일은 괜찮아요.
“I’m busy today. But tomorrow is fine.”
🔊 Listen: 오늘은 바빠요. 그런데 내일은 괜찮아요.
A: 그럼 내일 만나요.
“Then let’s meet tomorrow.”
🔊 Listen: 그럼 내일 만나요.
The topic marker contrasts today and tomorrow.
Conversation 5: Describing a Friend
A: 새로 온 친구는 어때요?
“What’s the new friend like?”
🔊 Listen: 새로 온 친구는 어때요?
B: 그 친구는 성격이 좋아요.
“That friend has a nice personality.”
🔊 Listen: 그 친구는 성격이 좋아요.
A: 한국어도 잘해요?
“Are they also good at Korean?”
🔊 Listen: 한국어도 잘해요?
B: 네, 한국어를 정말 잘해요.
“Yes, they speak Korean very well.”
🔊 Listen: 네, 한국어를 정말 잘해요.
Again, notice that a noun marked with 는 can establish the topic while another noun marked with 이/가 functions as the subject of a description.
12. Common Mistakes with Korean Particles
Understanding what learners commonly get wrong will help you avoid unnatural sentences.
Mistake 1: Choosing the Wrong Particle Form
Incorrect:
학생는
Correct:
학생은
🔊 Listen: 학생은
학생 ends in the consonant ㄱ, so use 은.
Incorrect:
친구은
Correct:
친구는
🔊 Listen: 친구는
친구 ends in a vowel, so use 는.
Mistake 2: Using 저가 Instead of 제가
Incorrect:
저가 할게요.
Correct:
제가 할게요.
🔊 Listen: 제가 할게요.
When the subject marker 가 attaches to 저, the resulting form is 제가.
Mistake 3: Assuming 은/는 Always Means Contrast
저는 학생이에요.
“I’m a student.”
🔊 Listen: 저는 학생이에요.
This can simply introduce the speaker’s background without contrasting them with another person.
Mistake 4: Assuming 이/가 Always Means New Information
고양이가 자고 있어요.
“The cat is sleeping.”
🔊 Listen: 고양이가 자고 있어요.
The speaker can use 가 even when the listener already knows which cat is being discussed.
The subject particle’s function is broader than introducing something new.
Mistake 5: Using 는 as the Only Possible Marker with a Person
Incorrect assumption:
“I should always use 는 when talking about myself or another person.”
But compare:
저는 민수예요.
“I’m Minsu.”
🔊 Listen: 저는 민수예요.
제가 민수예요.
“I’m Minsu.” / “I’m the one named Minsu.”
🔊 Listen: 제가 민수예요.
Both are grammatical, but their most natural situations differ.
Mistake 6: Ignoring Context
The biggest mistake is memorizing one fixed rule such as:
“은/는 is old information, and 이/가 is new information.”
This can be a useful introductory tendency, but it is not a universal rule.
A better question is:
What is the speaker doing in this conversation?
Are they establishing a topic, identifying someone, describing an event, or making a contrast?
Context helps explain the particle choice.
13. Korean Particles Listening Practice: Guess the Meaning
Now test your understanding by listening to paired sentences.
Instead of focusing only on the grammar, imagine which situation each sentence would naturally fit.
Listening Challenge 1: An Introduction
Listen to these two sentences separately.
🔊 Listen: 저는 선생님이에요.
🔊 Listen: 제가 선생님이에요.
Which sounds especially natural when someone asks, “Who is the teacher?”
Answer: 제가 선생님이에요.
The subject marker helps identify the person.
The other sentence is also grammatical but is more typical of a general introduction or a topic-based description.
Listening Challenge 2: Talking About Coffee
🔊 Listen: 커피가 맛있어요.
🔊 Listen: 커피는 맛있어요.
Imagine the speaker previously complained that the food was disappointing.
Which sentence more readily suggests “At least the coffee tastes good”?
Answer: 커피는 맛있어요.
The topic marker can highlight coffee in contrast to the food.
Listening Challenge 3: Who Came?
🔊 Listen: 민수가 왔어요.
🔊 Listen: 민수는 왔어요.
Someone asks, “Who came?”
Which answer most directly identifies the person?
Answer: 민수가 왔어요.
The particle 가 can focus the answer on the person’s identity.
Listening Challenge 4: Two Different Days
🔊 Listen: 오늘은 바빠요.
🔊 Listen: 내일은 괜찮아요.
What relationship do the two sentences express?
Answer: A contrast between today and tomorrow.
The topic marker helps organize the two days as contrasting topics.
Listening Challenge 5: Two Roles in One Sentence
🔊 Listen: 저는 한국어가 좋아요.
Which is the topic, and which is the subject?
Answer:
- 저는 — Topic: me
- 한국어가 — Subject: Korean language
- 좋아요 — Is good / liked
The sentence naturally expresses “I like Korean.”
A Useful Listening Strategy
When listening to Korean conversations:
- Identify the noun before the particle.
- Ask whether the speaker is establishing a topic or marking the subject.
- Consider what question the sentence is answering.
- Look for comparisons or contrasts.
- Listen again to the full sentence.
The best way to understand these particles is to connect grammar with conversation rather than only memorizing isolated sentences.

Answer Key and Explanations
1. A — 저는 학생이에요.
저는 establishes the speaker as the topic. It is a natural way to introduce yourself.
2. B — 민수가 왔어요.
민수가 directly identifies the person who came. 민수는 왔어요 is also grammatical, but it may establish or contrast Minsu as the topic instead of giving the most neutral focused answer to “Who came?”
3. C — 은
책 ends in the consonant ㄱ. The correct topic-marker form is 책은.
4. B — 가
친구 ends in a vowel. The correct subject-marker form is 친구가.
5. C — 제가 할게요.
제가 is a natural form for identifying yourself as the person volunteering. 저는 할게요 is also possible, but it can introduce or contrast your own action as a topic.
6. A — A comparison between food and coffee
The speaker contrasts the disappointing food with the delicious coffee.
7. A — 저는 한국어가 재미있어요.
저는 establishes the speaker as the topic, while 한국어가 is the grammatical subject of 재미있어요.
8. B — Topic vs. subject
Topic markers and subject markers have different grammatical functions. Information structure and context influence how they are interpreted.

15. How to Practice Korean Particles More Naturally
It’s easy to memorize the four particles in a few minutes. Using them naturally requires repeated exposure to real Korean sentences.
Here’s a study method you can practice.
Step 1: Master the Attachment Rules
First, memorize the simple spelling rules:
- Consonant + 은
- Vowel + 는
- Consonant + 이
- Vowel + 가
These rules are straightforward and should become automatic.
Step 2: Compare Sentence Pairs
Practice pairs such as:
저는 학생이에요.
🔊 Listen: 저는 학생이에요.
제가 학생이에요.
🔊 Listen: 제가 학생이에요.
Instead of asking which is correct, ask when each would be natural.
Step 3: Learn with Questions
Create a question such as:
누가 왔어요?
“Who came?”
🔊 Listen: 누가 왔어요?
Then practice an answer:
친구가 왔어요.
“My friend came.”
🔊 Listen: 친구가 왔어요.
Next, turn that person into the topic of a new sentence:
그 친구는 미국 사람이에요.
“That friend is American.”
🔊 Listen: 그 친구는 미국 사람이에요.
This trains you to recognize how a conversation develops.
Step 4: Practice Natural Korean Sentences
Keep a small notebook containing useful sentence patterns.
For example:
저는 ______이에요/예요.
“I’m…”
______이/가 왔어요.
“Someone/something came.”
______은/는 ______이/가 좋아요.
“As for someone or something, another thing is good or liked.”
Use nouns that are meaningful to your life.
Step 5: Review the Whole Sentence
Listening to just 은, 는, 이, or 가 isn’t enough to understand why a particle appears.
Always review the particle together with the noun and the complete sentence.

16. Frequently Asked Questions About Korean Particles
What is the difference between 은/는 and 이/가?
은/는 marks a topic, while 이/가 marks a grammatical subject. 은/는 is commonly used to establish a topic or create contrast. 이/가 is commonly used to identify a subject or present focused information. However, the precise meaning depends on context.
Is 저는 or 제가 correct?
Both are correct.
저는 is a topic-marked form, often used when talking about yourself.
제가 is a subject-marked form, often useful when identifying yourself as the person performing an action or answering a “who” question.
Does 은/는 always mean old information?
No. It can introduce a new topic. Its function is not limited to information already known by the listener.
Does 이/가 always introduce new information?
No. 이/가 can mark subjects that have already been mentioned or are familiar to everyone in the conversation.
Can a Korean sentence contain both 은/는 and 이/가?
Yes.
For example:
저는 한국어가 재미있어요.
“I find Korean interesting.”
🔊 Listen: 저는 한국어가 재미있어요.
저는 establishes the topic, and 한국어가 marks the subject of 재미있어요.
Why do Koreans sometimes omit particles?
Korean frequently omits information that can be understood from context. In casual conversation, particles may be omitted without making the sentence difficult to understand.
Should beginners memorize strict particle rules?
Memorize the basic consonant and vowel attachment rules, but avoid treating topic and subject usage as a rigid translation formula. Natural usage depends on what information the speaker wants to communicate.
How can I become better at using Korean particles?
Study short conversations, compare different particle choices, listen to complete sentences, and practice responding to realistic questions.
Final Review: Master Korean Particles 은/는 vs 이/가
You’ve now learned one of the most important distinctions in beginner Korean grammar.
Let’s review the basic rules.
| Particle | Used after | Main function |
|---|---|---|
| 은 | Consonant | Topic |
| 는 | Vowel | Topic |
| 이 | Consonant | Subject |
| 가 | Vowel | Subject |
Remember these key points:
1. 은/는 identifies the topic of conversation.
It can establish what the speaker wants to talk about or highlight a contrast.
2. 이/가 marks the grammatical subject.
It can also help identify the person or thing that answers a question.
3. Both can be natural with the same noun.
Their meaning and appropriateness depend on the conversational situation.
4. One sentence can contain both.
For example:
저는 한국어가 좋아요.
“I like Korean.”
🔊 Listen: 저는 한국어가 좋아요.
Final Listening Review: Five Essential Comparisons
Pair 1 — Self-introduction vs. identification
🔊 Listen: 저는 학생이에요.
🔊 Listen: 제가 학생이에요.
Pair 2 — General description vs. contrast
🔊 Listen: 커피가 맛있어요.
🔊 Listen: 커피는 맛있어요.
Pair 3 — Identifying a person vs. discussing that person
🔊 Listen: 민수가 왔어요.
🔊 Listen: 민수는 왔어요.
Pair 4 — Introducing and continuing information
🔊 Listen: 친구가 왔어요.
🔊 Listen: 그 친구는 미국 사람이에요.
Pair 5 — Topic and subject together
🔊 Listen: 저는 한국어가 재미있어요.
Your Final Challenge
Write a short Korean conversation containing at least five sentences.
Use:
- One sentence with 저는
- One sentence with 제가
- One sentence using 은 or 는 to make a contrast
- One sentence using 이 or 가 to identify the answer to a question
- One sentence containing both a topic marker and a subject marker
Then read each sentence aloud and listen to the matching examples from this lesson.
The goal is not to choose a particle by mechanically translating English. It’s to understand what your Korean sentence is doing in the conversation.
With regular listening and speaking practice, these particles will gradually begin to feel much more natural.
