Object Particle 을/를: The Target Marker
을/를 as a target sticker you place on the thing receiving the action (pizza, movie, homework).
Grammar Rule in 30 Seconds
Use 을 or 를 after a noun to show it is the object being acted upon by the verb.
- Use 을 after a noun ending in a consonant (e.g., 책을).
- Use 를 after a noun ending in a vowel (e.g., 사과를).
- The particle attaches directly to the noun without a space.
Overview
In Korean, the grammatical function of a noun is not dictated by its position within a sentence, but by the particles attached to it. This fundamental difference from languages like English, which relies heavily on word order, is a cornerstone of Korean grammar. The Object Particle 을/를 (eul/reul) serves a singular, unambiguous purpose: to mark the direct object of a transitive verb.
It directly signals which noun is receiving the action expressed by the verb.
Understanding 을/를 is essential for constructing clear, grammatically sound sentences. Without this particle, the intended meaning can become ambiguous or lost, as the sentence lacks a clear indicator of the action's target. For instance, in English, "I eat an apple" inherently places "apple" as the object.
In Korean, while context or word order might provide clues, 을/를 provides the definitive marker. Mastering this particle empowers you to express precisely what or whom your verb's action is affecting, forming the bedrock for more complex sentence structures.
How This Grammar Works
을/를 functions as a grammatical suffix, attaching directly to a noun. Its primary role is to identify that noun as the direct object of a transitive verb. A transitive verb is an action verb that requires a direct object to complete its meaning; it describes an action that is performed on something or someone.먹다 (to eat), 보다 (to see/watch), 마시다 (to drink), and 만들다 (to make) are prime examples of transitive verbs in Korean.을/를 is affixed to a noun, it explicitly communicates that this noun is the entity undergoing the verb's action. This mechanism ensures that the grammatical role of the noun remains unambiguous, even in cases of flexible Korean word order. Consider expressing "I eat bread." Here, 빵 (bread) is the object of the eating action.을/를 must be attached to 빵, forming 빵을 먹어요 (ppang-eul meogeoyo). The particle acts as a linguistic anchor, clearly designating the target of the action.Formation Pattern
을 (eul) and 를 (reul) is systematically determined by the final sound of the preceding noun. This phonetic rule, prevalent across many Korean particles, ensures smoother and more natural pronunciation. The choice hinges on whether the noun ends in a vowel (no final consonant) or a consonant (has a final consonant, known as 받침 batchim).
를. This combination facilitates a seamless phonetic flow. For example, 커피 (keopi, coffee) ends in the vowel sound /i/, thus becoming 커피를 (keopireul). Similarly, 사과 (sagwa, apple) concludes with a vowel sound /a/, resulting in 사과를 (sagwareul).
batchim), you attach 을. The ㅇ (ieung) in 을 serves as a crucial placeholder. It allows the final consonant of the preceding noun to link (or 'carry over') into the particle, easing pronunciation. For instance, 밥 (bap, rice/meal) ends in the consonant /p/, correctly becoming 밥을 (babeul). The /p/ sound effectively merges with 을 for a natural transition. Another example, 책 (chaek, book) ends in the consonant /k/, and thus transforms into 책을 (chaegeul).
를 | 친구 (friend) | 친구를 | chingureul (친구-를) |
피자 (pizza) | 피자를 | pijareul (피자-를) |
주스 (juice) | 주스를 | juseureul (주스-를) |
을 | 음악 (music) | 음악을 | eumageul (으마-글) |
연필 (pencil) | 연필을 | yeonpileul (연피-를) |
집 (house/home)| 집을 | jibeul (지-블) |
yeon-eum):
을, the final consonant of the noun invariably "links" or "carries over" to the initial vowel sound of the particle. This is a natural and mandatory phonetic phenomenon in Korean, vital for smooth and fluent speech. For example, 밥 (bap) + 을 (eul) combines to form 밥을, pronounced babeul. The ㅂ (b) sound from 밥 effectively moves to fill the empty ㅇ in 을. Similarly, 음악 (eumak) + 을 (eul) becomes 음악을, pronounced eumageul, with the ㄱ (k) sound linking into the particle.
yeon-eum is crucial. It is not an optional rule, but an intrinsic aspect of how these combinations are articulated by native speakers. Incorporating this linkage will significantly enhance the naturalness and comprehensibility of your Korean pronunciation.
When To Use It
을/를 is consistently employed whenever a noun functions as the direct recipient of an action performed by a transitive verb. Its usage is fundamental for grammatical correctness, ensuring clarity, and maintaining appropriate formality in communication.- 1Marking the Direct Object of Transitive Verbs: This is the particle's primary and most frequent application. Any noun that directly receives the action of a transitive verb must be marked with
을/를. This is a non-negotiable rule for forming grammatically correct sentences.
저는 한국어를 공부해요.(Jeoneun hangugeo-reul gongbuhaeyo.) - I study Korean. (한국어(Korean) is the direct object of공부하다(to study).)선생님이 질문을 하세요.(Seonsaengnim-i jilmun-eul haseyo.) - The teacher asks a question. (질문(question) is the direct object of하다(to do/ask).)민수 씨는 영화를 정말 좋아해요.(Minsu ssineun yeonghwa-reul jeongmal joahaeyo.) - Minsu really likes movies. (영화(movie) is the direct object of좋아하다(to like).)
- 1For Clarity in Complex Sentences: In sentences containing multiple clauses, adjectival phrases, or potentially ambiguous elements,
을/를becomes indispensable. It precisely isolates which noun is the direct recipient of a specific verb's action, preventing misinterpretation. This is particularly relevant given Korean's flexible word order.
저는 어제 친구와 함께 산 책을 읽었어요.(Jeoneun eoje chinguwa hamkke san chaeg-eul ilgeosseoyo.) - Yesterday, I read the book I bought with my friend. (Here,책(book) is clearly the object of읽었어요(read), disambiguating it from친구(friend), which is related via와 함께(with).)
- 1For Emphasis or Contrast: While
을/를is often omitted in informal speech, its explicit use can subtly emphasize the object. This draws attention to what is being acted upon, especially when there is an implicit selection or contrast. This is a common rhetorical device in natural Korean communication.
이 책을 읽으세요.(I chaeg-eul ilgeuseyo.) - Please read THIS book. (The particle emphasizes이 책(this book), perhaps contrasting it with other books.)저는 밥은 안 먹고 빵을 먹었어요.(Jeoneun bab-eun an meokgo ppang-eul meogeosseoyo.) - I didn't eat rice; I ate bread instead. (Here,빵을highlights the specific object that was eaten, contrasting it with밥은(rice, as for the topic).)
- 1In Formal Contexts and Writing: In formal settings, academic discourse, official documents, or when addressing elders or superiors, strict adherence to particle usage, including
을/를, is expected. Omitting particles in such contexts can be perceived as overly casual or even impolite, demonstrating a lack of grammatical precision. Maintaining을/를signifies respect and grammatical proficiency.
- Formal:
본 연구는 새로운 이론을 제시합니다.(Bon yeon-gu-neun saeroun iron-eul jesihapnida.) - This study presents a new theory. (Particle retained for formal, academic tone.) - Polite:
손님, 주문을 도와드릴까요?(Son-nim, jumun-eul dowadeurilkkayo?) - Customer, may I help you with your order? (Particle usage maintains polite, respectful address.)
을/를 is Often Omitted (in Casual Speech):을/를 is frequently omitted. This occurs when the meaning is unequivocally clear from the context or the verb itself strongly implies the object. This omission streamlines speech, contributing to a more natural, faster pace of conversation.- Formal/Textbook:
저는 김치를 좋아해요.(Jeoneun gimchireul joahaeyo.) - I like kimchi. - Casual Spoken:
나 김치 좋아해.(Na gimchi joahae.) - I like kimchi. (을/를is dropped,나is casual for저.)
- The object is already established or obvious to both participants in the conversation.
- The conversation is highly informal and fast-paced, where economy of speech is prioritized.
- The speaker aims for a more natural, less stilted sound. However, as an A1 learner, your priority should be correct usage, only considering omission once you have fully mastered the rule.
When Not To Use It
을/를 is fundamental for marking direct objects, its misapplication is a common source of grammatical error. Understanding when not to use it is as critical as knowing when to apply it, as incorrect usage can render a sentence ungrammatical or nonsensical.- 1With Descriptive Verbs (Adjectives): Korean grammar fundamentally distinguishes between action verbs (
동사dongsa) and descriptive verbs (형용사hyeongyongsa), which function much like adjectives. Descriptive verbs express states, qualities, or conditions rather than actions performed on an object. Consequently, they cannot take a direct object marked by을/를. Instead, the noun being described typically takes the Subject Particle이/가(i/ga).
- ❌
저는 음악을 좋아요.(Incorrect.좋다(to be good/likeable) is a descriptive verb. You cannot "good" music.) - ✅
저는 음악이 좋아요.(Jeoneun eumag-i joayo.) - I like music (literally, "Music is good to me.") - ❌
고양이를 귀여워요.(Incorrect.귀엽다(to be cute) is a descriptive verb.) - ✅
고양이가 귀여워요.(Goyang-iga gwiyeowoyo.) - The cat is cute.
좋아하다 (joahada, to like), is an action verb derived from 좋다. Because it expresses an active "liking" of something, it does correctly take 을/를.- ✅
저는 음악을 좋아해요.(Jeoneun eumag-eul joahaeyo.) - I like music.
- 1With Intransitive Verbs: Intransitive verbs describe actions that do not require a direct object; their action is not performed upon something or someone. These verbs often denote states of being, movement, or internal processes. Common examples include
가다(to go),오다(to come),자다(to sleep),앉다(to sit), and서다(to stand).
- ❌
저는 학교를 가요.(Incorrect.가다(to go) is intransitive.학교(school) is a destination, not an object being "gone.") - ✅
저는 학교에 가요.(Jeoneun hakgyoe gayo.) - I go to school. (Here,학교utilizes the locative particle에(e) to indicate destination.) - ❌
아기가 집을 자요.(Incorrect.자다(to sleep) is intransitive; you cannot "sleep" a house.) - ✅
아기가 집에서 자요.(Agiga jib-eseo jayo.) - The baby sleeps at home. (Here,집uses에서(eseo) to indicate the location where an action occurs.)
- 1When Other Particles Are Required: Certain verbs or grammatical constructions inherently demand specific particles other than
을/를to accurately convey their meaning. For example, verbs of giving or receiving typically use에게/한테(ege/hante) to mark the recipient, while verbs indicating direction or destination often use에(e) or으로/로(euro/ro).
- Recipient (에게/한테):
저는 친구에게 선물을 줘요.(Jeoneun chingu-ege seonmureul jwoyo.) - I give a gift to my friend. (Here,선물(gift) is the direct object taking을/를, but친구(friend) is the recipient, marked with에게.) - Location/Destination (에/으로):
저는 도서관에 가요.(Jeoneun doseogwan-e gayo.) - I go to the library. (The library is a destination, not an object.) - Instrument/Means (으로/로):
버스로 학교에 가요.(Beoseu-ro hakgyoe gayo.) - I go to school by bus. (The bus is the means, not a direct object.)
을/를 in these contexts is a common early-stage error. Always confirm whether the verb is truly transitive and requires a direct object, or if it is descriptive/intransitive and necessitates a different, more appropriate particle to express the intended grammatical relationship.Common Mistakes
을/를, often stemming from the grammatical interference of their native language or an incomplete understanding of Korean verb categorization. Identifying and actively correcting these prevalent errors is crucial for developing fluency and accuracy.- 1The Adjective Trap (Using
을/를with Descriptive Verbs): This is arguably the most common and persistent error. Learners mistakenly apply을/를to nouns preceding descriptive verbs (adjectives) because they attempt a direct translation of English object concepts. However, descriptive verbs do not describe an action performed on an object; they describe a state or quality inherent to a subject.
- Error:
저는 커피를 뜨거워요.(Incorrect.뜨겁다(to be hot) is an adjective. You cannot "hot" coffee.) - Correction:
저는 커피가 뜨거워요.(Jeoneun keopiga tteugeowoyo.) - The coffee is hot (to me). (Here,커피is the subject of the descriptive verb뜨겁다.) - Why it's wrong:
을/를signals that an action is directly applied to the noun. Descriptive verbs, by definition, describe inherent qualities or states, not actions that can be performed on something. Confusing them fundamentally misrepresents the grammatical relationship.
- 1Misapplying
을/를with Intransitive Verbs of Movement: Another frequent error involves using을/를with intransitive verbs like가다(to go) or오다(to come) when specifying a destination. These verbs describe movement, not an action performed on a location. Destinations are typically marked with the locative particle에(e).
- Error:
저는 도서관을 가요.(Incorrect.도서관(library) is a destination, not an object being "gone.") - Correction:
저는 도서관에 가요.(Jeoneun doseogwan-e gayo.) - I go to the library. - Why it's wrong: These verbs indicate movement towards or from a place. The
에particle specifically conveys destination, whereas을/를incorrectly implies the location is being acted upon as a direct object.
- 1Confusing
을/를when the Noun is the Subject of a State/Feeling: Sometimes, a noun that would appear as a direct object in English (e.g., "I hate cold weather") functions as the subject in a Korean sentence, especially when expressing feelings or states of being related to it. This often involves descriptive verbs or specific constructions.
- Error:
저는 수학을 어려워요.(Incorrect.어렵다(to be difficult) is an adjective.) - Correction:
저는 수학이 어려워요.(Jeoneun suhag-i eoryeowoyo.) - Math is difficult for me (literally, "As for me, math is difficult.") - Why it's wrong: In this construction,
수학(math) is the subject of the descriptive verb어렵다. The sentence describes the inherent difficulty of math, not an action being performed on math.
- 1Incorrect Pronunciation Linkage (
yeon-eum): While not a grammatical error per se, failing to apply theyeon-eumrule for nouns ending inbatchimfollowed by을can severely impact the naturalness and intelligibility of your spoken Korean. It often results in choppy or accented speech.
- Error (pronunciation): Articulating
책을as책-을(with a distinct pause or break between책and을). - Correction (pronunciation): Articulating
책을as채글(chaegeul), smoothly linking theㄱ(k) sound from책to을. - Why it's important: Natural
yeon-eumis a hallmark of native-like pronunciation and comprehension. It is a fundamental phonetic rule that makes Korean flow rhythmically, and ignoring it can make your speech sound unnatural or even lead to misinterpretation.

을/를 in practical application and provides readily usable expressions for daily communication.Contrast With Similar Patterns
을/를 due to their function of attaching to nouns. However, each particle possesses a distinct and specific grammatical role. Confusing these particles is a common pitfall for A1 learners.을/를, the Subject Particle 이/가, and the Topic Particle 은/는 is absolutely foundational for constructing accurate and naturally sounding Korean sentences.- 1
을/를(Object Marker):
- Function: Unambiguously marks the direct object of a transitive verb. It identifies the noun that is directly acted upon or affected by the verb's action.
- Focus: The specific target or recipient of the action.
- When to use: Always use with a noun that is the direct recipient of an action performed by a transitive verb.
- Example:
저는 물은 마셔요.(Jeoneun mur-eun masyeoyo.) - I drink water. (물(water) is the object being drunk.) - Example:
엄마가 옷을 만들어요.(Eommaga os-eul mandeureoyo.) - Mom makes clothes. (옷(clothes) is the object being made.)
- 1
이/가(Subject Marker):
- Function: Identifies the subject of a verb or a descriptive verb (adjective). It highlights who or what is performing the action or who or what is in a particular state or quality.
이/가typically introduces new information. - Focus: Emphasizes the subject itself, often in response to a question of identification ("Who is it?" or "What is it?") or to mark the subject of a descriptive verb.
- When to use:
- To introduce new information about the subject.
- To answer a "who?" or "what?" question, specifically identifying the agent.
- To mark the subject of a descriptive verb (
형용사), as they do not take objects. - Example:
눈이 와요.(Nun-i wayo.) - Snow is falling/It's snowing. (눈(snow) is the subject performing the action오다(to come/fall).) - Example:
저것이 버스예요.(Jeogeosi beoseuyeyo.) - That is a bus. (버스(bus) is the subject identified.) - Example:
날씨가 추워요.(Nalssiga chuwoyo.) - The weather is cold. (날씨(weather) is the subject of the descriptive verb춥다(to be cold).)
- 1
은/는(Topic Marker):
- Function: Marks the topic of the sentence. It sets the broader context or establishes what the sentence will be about, often implying a contrast or highlighting previously known information.
은/는can attach to subjects, objects, or even adverbs if they are the topic. - Focus: The overarching subject of discussion, established information, or for drawing a comparison/contrast.
- When to use:
- To introduce a general topic or established context, particularly at the beginning of a conversation or paragraph.
- To compare or contrast one element with another. When contrasting,
은/는takes on a strong "as for..." nuance. - Example:
저는 학생이에요.(Jeoneun haksaeng-ieyo.) - As for me, I am a student. (Establishes "I" as the topic of discussion.) - Example:
한국어는 어려워요.(Hangugeoneun eoryeowoyo.) - As for Korean, it is difficult. (Introduces Korean as the topic, potentially contrasting its difficulty with other subjects.) - Example (contrast):
사과는 맛있지만, 배는 맛없어요.(Sagwaneun masitjjiman, baeneun maseopseoyo.) - Apples are delicious, but pears are not. (Directly contrasts "apples" with "pears.")
책 - book) | Example (날씨 - weather) |을/를 | Direct Object | Target of action | 책을 읽어요. (Read a book.) | (Cannot be used; 날씨 not an object) |이/가 | Subject | New information; specific identifier; subject of descriptive verb | 책이 좋아요. (The book is good.) | 날씨가 좋아요. (The weather is good.) |은/는 | Topic | Established information; general topic; contrast | 책은 매일 읽어요. (As for books, I read them daily.) | 날씨는 춥지만 좋아요. (As for the weather, it's cold but good.) |이/가 and 은/는 can both mark subjects, their emphasis—new information for 이/가 versus established topics/contrast for 은/는—is distinct. 을/를, however, maintains a single, clear function: marking the direct object.을/를.Quick FAQ
을/를 particles in one sentence?In a single clause, generally no. A simple Korean sentence is designed to have one direct object that receives the action of its main transitive verb, hence one 을/를 particle. If an English sentence contains both a direct object and an indirect object (e.g., "I gave him a gift"), Korean uses different particles for the indirect object. The recipient of an action (indirect object) is typically marked with 에게 (ege) or 한테 (hante). For instance, "I gave my friend a gift" translates to 저는 친구에게 선물을 줬어요. (Jeoneun chingu-ege seonmureul jwosseoyo.) Here, 선물 (gift) is the direct object (taking 을/를), while 친구 (friend) is the indirect object (taking 에게). Attempting to use two 을/를 in a single clause is almost always grammatically incorrect and will sound unnatural.
을 or 를? Is there a safe way to guess?In very casual, rapid spoken Korean, native speakers do occasionally omit the object particle entirely if the meaning is perfectly clear from context. For example, 밥 먹어 (bap meogeo) instead of 밥을 먹어 (babeul meogeo). If you are genuinely unsure in a spoken context and the meaning remains unambiguous, omitting the particle is generally a "safer" conversational choice than selecting the wrong one (e.g., 친구을 or 밥를), which sounds distinctly unnatural and incorrect to a native ear. However, for written Korean, formal speech, or any situation where ambiguity might arise, always prioritize using the correct particle (을 for consonants, 를 for vowels). At your A1 level, focusing on correct usage is far more important than attempting advanced native-like omission, which can lead to miscommunication if not applied precisely.
을 always for consonants and 를 always for vowels?Yes, this rule for the object particle 을/를 is absolute and consistent. There are no exceptions where a noun ending in a vowel takes 을, or a noun ending in a consonant takes 를. This consistent pattern is a fundamental phonetic rule within Korean, specifically designed to facilitate smoother and more natural pronunciation. The ㅇ (ieung) in 을 functions as a phonological bridge, allowing the preceding consonant sound to link into the particle. Conversely, 를 directly follows a vowel sound without obstruction. This phonetic rule applies uniformly across all nouns and verbs when 을/를 functions as the object particle.
을/를 relate to Korean word order, which is often described as flexible?The existence and consistent use of particles like 을/를 are precisely what enable Korean's renowned word order flexibility. Because 을/를 explicitly marks the direct object, its grammatical role remains unchanged even if its position within the sentence shifts. For example, 저는 밥을 먹어요. (I eat rice.) can also be reordered as 밥을 저는 먹어요. or even 저는 먹어요 밥을. (though the latter is less common and might carry emphasis). The meaning "I eat rice" persists because 밥 is unequivocally marked as the object by 을. This highlights the crucial role of particles in Korean: they provide the structural clarity and semantic stability that word order provides in less inflected languages. Without 을/를, the flexibility of word order would indeed lead to complete grammatical chaos.
을/를 should be used?Yes, some verbs can be particularly challenging for learners, especially those that translate to English phrases involving prepositions but function as transitive verbs taking a direct object in Korean. A prime example is 듣다 (deutda, to listen). In English, we say "listen to music," which implies an indirect relationship. However, in Korean, 듣다 is a transitive verb, and the thing being listened to is its direct object.
- Correct:
저는 음악을 들어요.(Jeoneun eumag-eul deureoyo.) - I listen to music.
만나다 (mannada, to meet) also takes 을/를 for the person or thing being met, despite English often using "meet with" or "meet a person."- Correct:
저는 친구를 만나요.(Jeoneun chingu-reul mannayo.) - I meet a friend.

Memorize It
Mnemonic
Remember '을' has a consonant (like a block) and '를' is open like a vowel.
Visual Association
Imagine a magnet (the particle) snapping onto a metal ball (the noun). If the ball is flat (consonant), it needs the '을' magnet. If it's round (vowel), it needs the '를' magnet.
Rhyme
Consonant ends in 을, vowel ends in 를, that's the rule for you!
Story
Min-su is hungry. He sees an apple. He says '사과를' (apple-object) and then '먹어요' (eats). He is happy because he used the right particle.
