Topic Particle 은/는

은/는 marks the topic and often signals contrast — it is not simply a subject marker.

Grammar Rule in 30 Seconds

The topic particle 은/는 marks what you are talking about, setting the stage for the rest of your sentence.

  • Use 은 after a consonant: 책은 (the book).
  • Use 는 after a vowel: 나는 (I).
  • It highlights the topic, not necessarily the subject.
Topic + 은/는 + Comment

Overview

The Korean particle 은/는 (eun/neun) is not a simple translation for a specific English word, but rather a topic marker. Its fundamental role is to introduce or highlight the central theme or focus of a sentence or a conversation. Think of it as a signpost that tells your listener, "This is what I'm talking about right now." This particle is crucial for organizing your thoughts and guiding the flow of information in Korean.

Korean is considered a topic-prominent language. This means that establishing the topic often takes precedence over simply identifying the grammatical subject. 은/는 serves as the primary tool for this function.

Understanding this distinction from English, which is more subject-prominent, is a foundational step for beginners.

When you use 은/는, you're signaling that the information you're about to share relates directly to the marked noun. This marked noun is often something already known, generally understood, or being presented in a comparative light. Mastering 은/는 is essential for clear, natural, and nuanced communication in Korean.

How This Grammar Works

At its core, attaching 은/는 to a noun is like saying, "As for [noun]..." or "Speaking of [noun]...". This grammatical structure immediately draws attention to the noun as the main point of discussion for the upcoming statement. It frames the noun as the context for the information that follows, allowing you to establish a subject for general comment, shift conversational focus, or emphasize a commonly accepted truth.
Crucially, the noun marked by 은/는 does not always have to be the grammatical subject of the sentence. It can be an object, an adverbial phrase, or almost any element you wish to make the central theme. Its flexibility stems from its thematic function rather than a strict grammatical assignment.
For example, in 저는 학생이에요. (jeo-neun hak-saeng-i-e-yo., "I am a student."), (I) is both the topic and the grammatical subject. However, in 커피는 제가 마셨어요. (keo-pi-neun je-ga ma-syeot-sseo-yo., "As for the coffee, I drank it."), 커피 (coffee) is the topic, but (I) is the grammatical subject. This highlights 은/는's ability to direct focus without altering the noun's underlying grammatical role.
This ability to topicalize various sentence elements is a key characteristic of 은/는. It shows how Korean uses thematic structure to convey meaning, allowing for subtle shifts in emphasis that are vital for natural expression. By understanding this, you begin to grasp the inherent information hierarchy in Korean sentences.

Formation Pattern

1
Choosing between and is determined by the final sound of the noun or pronoun it attaches to. This rule ensures smooth pronunciation and is consistent across all applications of the particle. Adhering to this phonetic rule is fundamental for sounding natural in Korean.
2
Use after a noun or pronoun ending in a consonant (받침, batchim).
3
Use after a noun or pronoun ending in a vowel (no batchim).
4
Always check the last syllable of the word to which you are attaching 은/는. This simple rule is applied without exception.
5
| Ending Sound | Particle | Example Noun (English) | Example Noun (Korean) | Combined Form (Korean) | Romanization | Meaning (Literal) |
6
| :----------- | :------- | :--------------------- | :-------------------- | :--------------------- | :----------------- | :--------------------- |
7
| Consonant | | rice | | 밥은 | bap-eun | As for rice |
8
| Consonant | book | | 책은 | chaek-eun | As for the book |
9
| Consonant | Korea | 한국 | 한국은 | han-guk-eun | As for Korea |
10
| Vowel | | I (informal) | | 나는 | na-neun | As for me |
11
| Vowel | friend | 친구 | 친구는 | chin-gu-neun | As for the friend |
12
| Vowel | coffee | 커피 | 커피는 | keo-pi-neun | As for coffee |
13
This rule also applies to personal pronouns. (formal 'I') ends in a vowel, so it becomes 저는 (jeo-neun). (informal 'I') also ends in a vowel, becoming 나는 (na-neun), which often contracts to (nan) in casual speech, such as 난 학생이야. ("I'm a student."). These contractions are common and help Korean sound more fluid.

When To Use It

은/는 serves several key functions in Korean, primarily centered around establishing context, making general statements, and highlighting distinctions. Understanding these uses is fundamental for building comprehensive sentences.
  1. 1Introducing a General Topic or Making a First Mention (Context Setting):
You use 은/는 to introduce a subject for the first time, establishing it as the main discussion point. This sets the stage for further comments or details about that topic. It's often used when you're starting a new conversational thread.
  • 저는 김민수입니다. (jeo-neun Kim Min-su-im-ni-da., "I am Kim Minsu.") Here, you introduce yourself as the topic.
  • 이것은 제 가방이에요. (i-geot-eun je ga-bang-i-e-yo., "This is my bag.") You're introducing "this" as the topic to describe it.
  • 제 취미는 독서예요. (je chwi-mi-neun dok-seo-ye-yo., "My hobby is reading.") Your hobby is introduced as the topic for definition.
  1. 1Making General Statements or Definitions (Universal Truths & Characteristics):
This particle is ideal for discussing something in a broad sense, often stating a definition, a common characteristic, or a generally accepted truth. 은/는 signals that the information presented applies generally to the topicalized noun, rather than a specific instance.
  • 고양이는 귀여워요. (go-yang-i-neun gwi-yeo-wo-yo., "Cats are cute.") This is a general observation about cats.
  • 사과는 맛있어요. (sa-gwa-neun ma-si-sseo-yo., "Apples are delicious.") A general statement of opinion about apples.
  • 지구는 둥글어요. (ji-gu-neun dung-geul-eo-yo., "The Earth is round.") A universal fact about the Earth.
  1. 1Highlighting Contrast or Comparison (Emphasis on Distinction):
This is one of the most powerful and frequent applications of 은/는. It often implies a comparison or a subtle contrast, even if the 'other side' of the comparison is not explicitly stated. The particle draws attention to the topic in distinction to other potential topics or expectations.
It says, "as for this, it's X, but other things might be Y."
  • 저는 커피는 안 마셔요. (jeo-neun keo-pi-neun an ma-syeo-yo., "As for coffee, I don't drink it.") This implies you might drink other beverages, but not coffee.
  • 오늘은 날씨가 좋지만 내일은 비가 올 거예요. (o-neul-eun nal-ssi-ga jot-ji-man nae-il-eun bi-ga ol geo-ye-yo., "Today the weather is good, but tomorrow it will rain.") This is a direct contrast between today's and tomorrow's weather.
  • 김치는 맵지만 비빔밥은 안 매워요. (kim-chi-neun maep-ji-man bi-bim-bap-eun an mae-wo-yo., "Kimchi is spicy, but bibimbap isn't spicy.") Here, 은/는 highlights the differing spice levels of the two dishes.
  1. 1Referring to Existing or Shared Information (Re-establishing a Topic):
Once a topic has been introduced or is mutually understood by both the speaker and listener, 은/는 can be used to re-establish it as the current subject of discussion. This reinforces that the topic is already 'on the table' and continues the conversation about it.
  • A: 민수 씨는 어디 있어요? (Min-su ssi-neun eo-di i-sseo-yo?, "Where is Minsu?")
B: 민수 씨는 지금 회사에 있어요. (Min-su ssi-neun ji-geum hoe-sa-e i-sseo-yo., "Minsu is at the company now.") Minsu was established by the question and is confirmed as the topic for the answer.
  • 그 영화는 정말 재미있어요. (geu yeong-hwa-neun jeong-mal jae-mi-i-sseo-yo., "That movie is really interesting.") This assumes you both know which movie is being discussed.
  1. 1Topicalizing Non-Subjects (Objects, Adverbs, etc.):
A strong indicator of 은/는's function as a topic marker, independent of grammatical role, is its ability to attach to elements other than the subject. This includes direct objects, adverbs of time or place, and other sentence components, shifting the sentence's focus to that particular element.
  • 책은 읽었어요. (chaek-eun ilg-eot-sseo-yo., "As for the book, I read it.") Here, (book), which is the grammatical object, is topicalized. The subject 저/나 is often omitted as it's implied.
  • 오늘은 학교에 안 가요. (o-neul-eun hak-gyo-e an ga-yo., "As for today, I'm not going to school.") The time adverb 오늘 (today) is topicalized, setting the temporal context for the action.
  • 한국 음식은 다 좋아해요. (han-guk eum-sik-eun da jo-a-hae-yo., "As for Korean food, I like it all.") The direct object 한국 음식 is topicalized, emphasizing that specific category of food.

When Not To Use It

While 은/는 is versatile, its misuse can make your Korean sound unnatural or convey unintended meanings. It's especially important for beginners to know when to avoid it, particularly in contrast with 이/가.
  1. 1Identifying New, Specific Information (Requires 이/가):
If you are introducing a new, specific subject into the conversation, or identifying who or what exactly performs an action or possesses a quality for the first time, you should almost always use 이/가. Using 은/는 here would inappropriately imply a contrast or a general statement where none is intended, making the sentence awkward.
  • Q: 누가 왔어요? (nu-ga wa-sseo-yo?, "Who came?")
A: 선생님이 왔어요. (seon-saeng-nim-i wa-sseo-yo., "The teacher came.") 선생님 is the new, specific information identifying who came. Using 선생님은 왔어요. would imply "The teacher came (but perhaps someone else didn't)", which isn't the neutral answer to a "who" question.
  1. 1Subjects of Interrogative Words (Question Words):
When a question word (누구? who?, 무엇? what?, 어느 것? which one?) functions as the grammatical subject of a sentence, it must be marked with 이/가. You are asking for an exhaustive identification of who or what fills that subject role, which is 이/가's function.
  • 무엇이 필요해요? (mu-eot-i pil-yo-hae-yo?, "What is needed?") Not 무엇은 필요해요?
  • 누가 창문을 깼어요? (nu-ga chang-mun-eul kkaet-sseo-yo?, "Who broke the window?") Not 누구는 창문을 깼어요?
  1. 1Subjects within Subordinate (Embedded) Clauses:
This is a strict grammatical rule that applies even at advanced levels. 은/는 cannot mark the subject of a subordinate or embedded clause. These clauses modify nouns or function as part of a larger sentence, and their subjects require 이/가 (or to be omitted if context is perfectly clear).
The identification function of 이/가 is necessary within these modifying structures.
  • Correct: [제가 만든] 음식은 맛있어요. ([je-ga man-deun] eum-sik-eun ma-si-sseo-yo., "The food [that I made] is delicious.") is the subject of the embedded clause 제가 만든.
  • Incorrect: [저는 만든] 음식은 맛있어요.
  1. 1With Existential Verbs 있다 (to be, to exist, to have) and 없다 (to not be, to not exist, to not have) (without explicit contrast):
For simple statements of existence or possession using 있다 and 없다, 이/가 is the natural and default particle to mark the subject. While 은/는 can be used with these verbs, it specifically introduces a strong sense of contrast or comparison, or a general statement. If there's no contrast intended, use 이/가.
  • 시간이 없어요. (si-gan-i eop-seo-yo., "I don't have time.") This is a neutral statement of lack.
  • 강아지가 있어요. (gang-a-ji-ga i-sseo-yo., "There is a puppy / I have a puppy.") A neutral statement of existence or possession.
  • Compare with contrast: 돈은 있지만 시간은 없어요. (don-eun it-ji-man si-gan-eun eop-seo-yo., "I have money, but I don't have time.") Here, 은/는 is correctly used for the explicit contrast between money and time.

Common Mistakes

Understanding where beginners typically stumble with 은/는 will help you avoid these pitfalls and progress more quickly. These errors often arise from applying English grammatical logic to Korean.
  1. 1Overusing 은/는 as a Universal Subject Marker:
A very common mistake is treating 은/는 as the Korean equivalent of "the" or a general subject marker. Remember, 은/는 marks the topic, which often implies a contrast or a general statement. If you use 은/는 when 이/가 is more appropriate, your sentences can sound stiff, formal, or convey an unintended contrasting nuance.
  • Incorrect: 어제는 친구는 만났어요. (eo-je-neun chin-gu-neun man-na-sseo-yo.) This awkwardly topicalizes both 어제 and 친구 in a contrasting way.
  • Correct: 어제 친구를 만났어요. (eo-je chin-gu-reul man-na-sseo-yo., "I met a friend yesterday.") This is a neutral statement; 친구 is simply the object of the verb.
  1. 1Confusing 은/는 with 이/가 for New Information/Identification:
This is perhaps the most critical distinction. If you're introducing a new, specific subject into the conversation, or exhaustively identifying who or what performs an action, 이/가 is the correct choice. Using 은/는 in such a context would incorrectly suggest a contrast or that the information is already known.
  • Incorrect: 창문은 깨졌어요. (chang-mun-eun kkae-jyeo-sseo-yo.) This sounds like you're contrasting the window with something else that didn't break. You're likely just reporting a new event.
  • Correct: 창문이 깨졌어요. (chang-mun-i kkae-jyeo-sseo., "The window broke.") This simply states a new event, identifying the subject of the action.
  1. 1Incorrect Batchim Application:
While it seems basic, mixing up and due to the preceding word's final sound is a frequent error, especially in rapid speech. Always take a moment to confirm whether the noun ends in a consonant (use ) or a vowel (use ).
  • Incorrect: 나은 학생이에요. (na-eun hak-saeng-i-e-yo.) (Incorrectly using after the vowel .)
  • Correct: 나는 학생이에요. (na-neun hak-saeng-i-e-yo., "I am a student.")
  • Incorrect: 밥는 맛있어요. (bap-neun ma-si-sseo-yo.) (Incorrectly using after the consonant .)
  • Correct: 밥은 맛있어요. (bap-eun ma-si-sseo-yo., "Rice is delicious.")

Common Collocations

Certain nouns, pronouns, and phrases are very frequently used with 은/는 to form natural Korean expressions. Learning these common pairings helps you internalize the particle's usage and allows you to communicate more fluently. These aren't rigid rules but rather strong tendencies in everyday speech.
  • Personal Pronouns:
  • 저는 (jeo-neun) / 나는 (na-neun): "I + topic particle" (formal/informal). 나는 often contracts to (nan) in casual contexts, e.g., 난 몰라. (nan mol-la., "I don't know.")
  • 당신은 (dang-sin-eun): "You + topic particle" (often used carefully, not always a direct "you").
  • Demonstrative Pronouns:
  • 이것은 (i-geot-eun) / 이건 (i-geon): "This + topic particle". 이건 is a very common spoken contraction, e.g., 이건 제 핸드폰이에요. (i-geon je haen-deu-pon-i-e-yo., "This is my phone.")
  • 그것은 (geu-geot-eun) / 그건 (geu-geon): "That + topic particle" (for something near the listener or previously mentioned), e.g., 그건 아니에요. (geu-geon a-ni-e-yo., "That's not it.")
  • 저것은 (jeo-geot-eun) / 저건 (jeo-geon): "That + topic particle" (for something far from both speaker and listener).
  • Time Adverbs: These are extremely common for setting the temporal topic of a sentence.
  • 오늘은 (o-neul-eun): "As for today", e.g., 오늘은 날씨가 좋아요. (o-neul-eun nal-ssi-ga jo-a-yo., "Today, the weather is good.")
  • 내일은 (nae-il-eun): "As for tomorrow"
  • 주말은 (ju-mal-eun): "As for the weekend"
  • Adverbs/Phrases Introducing Opinion or Fact:
  • 사실은 (sa-sil-eun): "Actually; as for the truth". Often introduces clarification or a surprising fact, e.g., 사실은 제가 어제 못 갔어요. (sa-sil-eun je-ga eo-je mot ga-sseo-yo., "Actually, I couldn't go yesterday.")
  • 개인적으로는 (gae-in-jeok-eu-ro-neun): "Personally speaking; as for my personal opinion". Used to introduce a personal viewpoint.
  • Generalizing Phrases:
  • 보통은 (bo-tong-eun): "Usually; as a general matter". Sets a general habit or usual condition as the topic, e.g., 보통은 아침에 커피를 마셔요. (bo-tong-eun a-chim-e keo-pi-reul ma-syeo-yo., "Usually, I drink coffee in the morning.")
  • 대부분은 (dae-bu-bun-eun): "Mostly; for the most part".

Contrast With Similar Patterns

Distinguishing 은/는 from 이/가 is the most crucial and often challenging distinction for Korean learners. While both attach to nouns and can sometimes seem to mark a subject, their underlying functions are fundamentally different and dictate the meaning and nuance of your sentences. Grasping this contrast is paramount for natural Korean communication.
은/는 (Topic Particle) vs. 이/가 (Subject Particle)
| Feature | 은/는 (Topic Particle) | 이/가 (Subject Particle) |
| :------------------- | :-------------------------------------------------------------- | :------------------------------------------------------------- |
| Primary Function | Marks the topic or theme of the discourse. Sets the context or general subject of discussion. | Marks the grammatical subject of the verb or adjective. Identifies the actor or entity that performs the action/state. |
| Information Status | Typically refers to old, known, or general information. Assumes the listener knows what you're generally talking about. | Typically refers to new, unknown, or specific information. Introduces a specific entity or exhaustively identifies it. |
| Emphasis | Focuses on the comment about the topic. Often implies contrast or comparison with other possible topics. | Focuses on the subject itself (exhaustive identification). It answers "who?" or "what?" uniquely and exclusively. |
| Scope | Can apply broadly across multiple sentences or a paragraph, setting a sustained topic for an entire discussion. | Applies specifically to the subject of the immediate clause. Its influence is localized to the sentence in which it appears. |
| Answers What? | Answers "What about X?" or "As for X, what do you know/say?" | Answers "Who/What is X?" or "Who/What did it?" (exhaustive). |
| Existence Verbs (있다/없다) | Used to introduce contrast: 돈은 있어요. ("I have money (but not other things)"). | Default for simple existence/possession: 돈이 있어요. ("I have money"). |
| Subordinate Clauses | Cannot mark subjects within subordinate clauses. | Must mark subjects within subordinate clauses (or omit if context is perfectly clear). |
Detailed Examples of 은/는 vs. 이/가:
  1. 1General vs. Specific / Known vs. New Information:
  • 은/는 for a general truth: 한국 음식은 맛있어요. (han-guk eum-sik-eun ma-si-sseo-yo., "Korean food is delicious.") This is a general statement about Korean food as a category.
  • 이/가 for new, specific information: 이 음식이 맛있어요. (i eum-sik-i ma-si-sseo-yo., "This food is delicious.") You're identifying a specific dish that is delicious, perhaps one you just tasted.
  1. 1Contrast vs. Exhaustive Identification:
  • 은/는 for contrast: 저는 한국어를 공부해요. 일본어는 안 해요. (jeo-neun han-guk-eo-reul gong-bu-hae-yo. il-bon-eo-neun an hae-yo., "I study Korean. As for Japanese, I don't.") The clearly contrasts your study of Korean with the non-study of Japanese.
  • 이/가 for exhaustive identification: A: 누가 학생이에요? (nu-ga hak-saeng-i-e-yo?, "Who is the student?") B: 제가 학생이에요. (je-ga hak-saeng-i-e-yo., "I am the student.") This emphasizes that only I am the student, identifying the unique person.
  1. 1Topic of Discussion vs. Grammatical Subject:
  • 은/는 can mark the topic, which may not be the grammatical subject: 커피는 제가 마셨어요. (keo-pi-neun je-ga ma-syeot-sseo-yo., "As for the coffee, I drank it.") 커피 is the topic, but is the grammatical subject.
  • 이/가 strictly marks the grammatical subject: 제가 커피를 마셨어요. (je-ga keo-pi-reul ma-syeot-sseo-yo., "I drank the coffee.") Here, is the subject.
은/는 (Topic Particle) vs. 을/를 (Object Particle)
While both 은/는 and 을/를 attach to nouns, their functions are entirely distinct. Confusing them means confusing thematic focus with grammatical function. 을/를 specifically marks the direct object of a transitive verb, indicating the receiver of an action.
은/는, even when attached to an object, primarily marks it as the sentence's topic, adding nuance of contrast or generalization.
  • 저는 밥을 먹어요. (jeo-neun bap-eul meok-eo-yo., "I eat rice.") is the neutral direct object of 먹다 (to eat).
  • 밥은 먹어요. (bap-eun meok-eo-yo., "As for rice, I eat it.") is topicalized, perhaps implying "I eat rice (but not other things)" or "Speaking of rice, that's what I eat." The subject is usually omitted as understood.

Quick FAQ

These questions address common curiosities and help solidify your understanding of 은/는.
Q: Can 은/는 always be translated as "as for" or "speaking of"?

While these translations effectively capture the essence of 은/는's topical function, they don't always sound natural or necessary in English. The nuance is often subtle and understood from context. It's more accurate to think of 은/는 as a topic indicator that guides the listener's attention, rather than seeking a direct, one-to-one translation.

Q: Why do Koreans sometimes drop 은/는 completely?

Korean is a highly contextual language. Native speakers frequently omit particles and even entire sentence components (like the topic or subject) when the meaning is unambiguous from the situation or previous conversation. For instance, if you're holding a cup of tea and someone asks about it, you might simply say 맛있어요 (ma-si-sseo-yo, "It's delicious") with 차는 (cha-neun) or 이것은 (i-geot-eun) understood. For A1 learners, it is generally advisable to use particles until you develop a strong intuition for when they can be safely omitted.

Q: Does 은/는 always mark the grammatical subject?

No, this is a common misconception and a crucial point to understand. 은/는 marks the topic, which can and often does coincide with the grammatical subject (e.g., 저는 학생이에요. – "I am a student."). However, it can also topicalize the object (e.g., 커피는 좋아해요. – "As for coffee, I like it.") or an adverbial phrase (e.g., 오늘은 쉬는 날이에요. – "As for today, it's a day off."). Its role is thematic and contextual, not strictly limited to the grammatical subject.

Q: Can 은/는 be used in questions?

Yes, 은/는 can be used in questions, especially when making a general inquiry about an established topic or implying a contrast. For example, 민수 씨는 어디에 있어요? (Min-su ssi-neun eo-di-e i-sseo-yo?, "As for Minsu, where is he?") This is a neutral question about an existing topic. However, if you are asking to identify who or what is performing an action (e.g., "Who came?"), then 이/가 is used with the interrogative pronoun (누가 왔어요?).

Q: Can 은/는 be used directly with verbs or adjectives?

No. 은/는 is a particle that attaches to nouns, pronouns, or noun phrases. It cannot directly attach to a verb stem or an adjective stem. If you want to topicalize an action or state, you would first nominalize the verb or adjective (turn it into a noun phrase), then attach 은/는. You'll learn about nominalization at a later stage in your Korean studies.

Q: What is the most important thing for an A1 learner to remember about 은/는?

For an A1 learner, the most important takeaway is to recognize 은/는 as a topic marker that introduces the general subject of your discussion, often implying a general statement or contrast. When you want to state a specific, new fact or identify who/what specifically did something, lean towards 이/가. This fundamental distinction is your biggest guide.
