Present Tense Modifiers: -는 (The 'who/which/that' for action verbs)
Grammar Rule in 30 Seconds
Use -는 to turn an action verb into a description for a noun, like 'the person who is eating'.
- Attach -는 directly to the verb stem (e.g., 먹다 -> 먹는).
- If the stem ends in ㄹ, drop the ㄹ and add -는 (e.g., 만들다 -> 만드는).
- The modified noun follows the verb (e.g., 책을 읽는 학생).
Overview
When constructing descriptive phrases in Korean, particularly those involving an action verb modifying a noun in the present tense, you utilize the adnominal ending -는 (-neun). This grammatical element functions as a present participial marker, effectively transforming an action verb phrase into a clause that describes a subsequent noun. Think of it as the Korean equivalent of English relative clauses like "who is doing," "which is doing," or "that does/is doing," but with a critical structural difference: the modifying clause precedes the noun it describes.
Unlike English, where the noun often comes first followed by a relative pronoun and verb (e.g., "the person who drinks coffee"), Korean places the entire descriptive action phrase before the noun. For instance, "the person who drinks coffee" becomes 커피를 마시는 사람 (keopireul masineun saram). Here, 마시는 (masineun)—derived from the verb 마시다 (to drink) with -는 attached—modifies 사람 (person).
Mastering -는 is fundamental for progressing beyond basic sentence structures and achieving natural conversational fluency, allowing you to articulate complex ideas and descriptions efficiently.
This pattern reflects a core principle of Korean grammar: modifiers always precede the modified element. The verb 마시다 becomes 마시는, operating syntactically like an adjective for the noun 사람. This allows you to combine multiple simple sentences into a single, cohesive phrase.
For example, instead of saying 그 사람이 커피를 마셔요. 그 사람은 제 친구예요. (That person drinks coffee. That person is my friend.), you can elegantly combine them into 커피를 마시는 사람이 제 친구예요. (The person drinking coffee is my friend.).
This integration of action into description is a cornerstone of B1-level Korean sentence construction.
How This Grammar Works
책을 읽다 (chaegeul ikda – to read a book). If you want to say "the person reading a book," you take the verb stem 읽 (ik), attach -는 to form 읽는 (ingneun), and then place the noun 사람 (saram) after it: 책을 읽는 사람 (chaegeul ingneun saram). The complete phrase 책을 읽는 now modifies 사람.동사, dongsa) and indicates either a present progressive action (what is currently happening) or a habitual/general action (what regularly happens or is generally true). You cannot use -는 with descriptive verbs (형용사, hyeong-yongsa, often translated as adjectives in English), such as 예쁘다 (to be pretty) or 크다 (to be big). For descriptive verbs, a different adnominal ending, -(으)ㄴ (-(eu)n), is used (e.g., 예쁜 사람 – a pretty person).있다 (itda – to exist/have) and 없다 (eopda – to not exist/not have). While these verbs often function descriptively in English (e.g., "There is water," "I have a book"), grammatically in Korean they are classified as action verbs for the purpose of adnominal modification. Therefore, they always take -는.재미있다 (to be interesting/fun) becomes 재미있는 (jaemiittneun) to modify a noun like 영화 (movie), resulting in 재미있는 영화 (an interesting movie). Similarly, 돈이 없는 사람 (don-i eopneun saram) means "a person who doesn't have money." This grammatical classification is a key distinction that often challenges learners, as it diverges from their native language intuition about verbs and adjectives.Formation Pattern
-는 directly to the verb stem, regardless of whether the stem ends in a vowel or a consonant. There are no vowel harmony considerations as seen in some other Korean conjugations, simplifying its application significantly.
다 (da) to get the verb stem.
-는 (-neun) directly to this stem.
-는 | Example Phrase | Meaning | Formal 해요체 / 합니다체 |
가다 (to go) | 가 | 가는 | 가는 길 (ganeun gil) | The road I'm going on | 가는 길이에요 / 가는 길입니다 |
먹다 (to eat) | 먹 | 먹는 | 먹는 음식 (meongneun eum-sik) | The food I'm eating | 먹는 음식이에요 / 먹는 음식입니다 |
있다/없다 | 있다 (to exist) | 있 | 있는 | 있는 시간 (ittneun sigan) | The available time | 있는 시간이에요 / 있는 시간입니다 |
있다/없다 | 재미있다 (to be fun) | 재미있 | 재미있는 | 재미있는 영화 (jaemiittneun yeonghwa) | An interesting movie | 재미있는 영화예요 / 재미있는 영화입니다 |
있다/없다 | 맛없다 (to be tasteless) | 맛없 | 맛없는 | 맛없는 음식 (mas-eopneun eum-sik) | Food that isn't tasty | 맛없는 음식이에요 / 맛없는 음식입니다 |
ㄹ Irregular (리을 불규칙):
ㄹ (rieul), the ㄹ drops when followed by -는. This ㄹ drop occurs because ㄹ cannot be immediately followed by ㄴ (nieun), ㅂ (bieup), or ㅅ (siot) in Korean phonology. This is a common pattern in Korean grammar, so recognizing it here will help you with other conjugations later.
ㄹ Drop (before ㄴ) | + -는 | Example Phrase | Meaning |
만들다 (to make) | 만들 | 만드 | 만드는 | 만드는 방법 (mandeuneun bangbeop) | The method of making (the way to make) |
살다 (to live) | 살 | 사 | 사는 | 서울에 사는 사람 (seoul-e saneun saram) | The person who lives in Seoul |
열다 (to open) | 열 | 여 | 여는 | 문을 여는 사람 (mun-eul yeoneun saram) | The person opening the door |
알다 (to know) | 알 | 아 | 아는 | 제가 아는 사람 (jega aneun saram) | The person I know |
-는. However, there must be a space between -는 and the noun it modifies. For instance, 먹는음식 ❌ is incorrect; it should always be 먹는 음식 ✅.
When To Use It
- Describing Current or Progressive Actions: Use
-는to indicate an action that is presently occurring or in progress. This allows you to identify or specify a noun based on what it is doing right now. 지금 책을 읽는 아이가 제 동생이에요.(jigeum chaegeul ingneun aiga je dongsaeng-ieyo.) – The child reading a book right now is my younger sibling.저기서 춤추는 사람이 누구예요?(jeogiseo chumchuneun saram-i nugu-eyo?) – Who is that person dancing over there?- Indicating Habitual, Regular, or General Actions:
-는is also used to describe an action that occurs habitually, regularly, or as a general truth associated with the noun. This is common when discussing routines, preferences, or characteristics. 매일 운동하는 사람은 건강해요.(mae-il undonghaneun saram-eun geonganghaeyo.) – A person who exercises daily is healthy.제가 자주 가는 카페는 저기예요.(jega jaju ganeun kape-neun jeogi-eyo.) – The cafe I often go to is over there.- Identifying or Specifying Nouns: This modifier is essential for singling out a particular noun from a group based on its associated action or attribute. It helps answer "which one?" or "what kind?"
우리가 주문하는 음식은 비빔밥이에요.(uri-ga jumunhaneun eum-sik-eun bibimbab-ieyo.) – The food we are ordering is bibimbap.네가 좋아하는 가수는 누구야?(ne-ga joh-ahaneun gasu-neun nugu-ya?) – Who is the singer you like?- Describing Purpose or Function: When a noun's purpose or function is defined by an action,
-는is the appropriate modifier. This applies to objects, tools, or concepts. 이것은 물을 끓이는 주전자예요.(igeoseun mul-eul kkeur-ineun jujanjeo-eyo.) – This is a kettle that boils water.글을 쓰는 데 사용하는 펜이에요.(geureul sseuneun de sayonghaneun pen-ieyo.) – It's a pen used for writing.
-는 serves as the indispensable link. It allows you to create dense, information-rich phrases, which is a hallmark of native-like Korean expression.Common Mistakes
-는 adnominal ending. Recognizing these common pitfalls and understanding why they occur will significantly accelerate your mastery of this crucial grammatical pattern.- 1Using
-는with Descriptive Verbs (Adjectives): This is perhaps the most frequent error. Many learners instinctively try to use-는with descriptive verbs because these often translate as adjectives in English. However, Korean distinguishes strictly between action verbs and descriptive verbs for adnominal modification.
- Incorrect:
예쁘는 여자(yeppeuneun yeoja) ❌ (Trying to say "a pretty woman" with-는) - Reasoning:
예쁘다(to be pretty) is a descriptive verb. For descriptive verbs in the present tense, you must use the-(으)ㄴ(-(eu)n) adnominal ending. - Correct:
예쁜 여자(yeppeun yeoja) ✅ - Important: Remember the special case of
있다/없다. Although재미있다(to be interesting) feels descriptive, it grammatically behaves like an action verb and correctly takes-는(e.g.,재미있는 영화).
- 1Forgetting the
ㄹDrop (리을 불규칙): As detailed in the formation section, verbs with stems ending inㄹexhibit an irregular conjugation when followed by-는. Overlooking this rule results in grammatically incorrect and often phonetically awkward phrases.
- Incorrect:
서울에 살는 친구(seoul-e salneun chingu) ❌ (Trying to say "a friend who lives in Seoul") - Reasoning: The
ㄹin살다(to live) drops before-는due to phonological rules preventingㄹfrom being directly followed byㄴ. - Correct:
서울에 사는 친구(seoul-e saneun chingu) ✅
- 1Incorrect Word Order (L1 Interference): Directly translating from English, which places the noun first in relative clauses, is a common source of error. Korean requires the entire modifying clause to precede the noun.
- Incorrect:
책 읽는(chaek ingneun) ❌ (If you intend to say "the book being read") - Reasoning: This is a partial phrase. The noun being modified must come after the
는form. If you mean "the book I'm reading," it should be제가 읽는 책(jega ingneun chaek). If you mean "reading a book," it would be책을 읽어요or책 읽기. - Correct:
읽는 책(ingneun chaek) ✅ (the book being read) or내가 읽는 책(nae-ga ingneun chaek) ✅ (the book that I am reading).
- 1Confusing
-는(Adnominal) with은/는(Topic Marker): Although visually similar, these two grammatical elements serve entirely different functions.
- Topic Marker (
은/는): Attaches to nouns to indicate the topic of a sentence (e.g.,저는 학생이에요.–Jeo-neun haksaeng-ieyo.– As for me, I am a student). - Adnominal Modifier (
-는): Attaches to action verb stems to create a clause that modifies a subsequent noun (e.g.,제가 먹는 음식–je-ga meongneun eum-sik– the food that I eat). - Key Distinction: The topic marker highlights the subject or topic of the main clause. The adnominal
-는is part of a subordinate clause that describes a noun. They exist in different syntactic environments.
- 1Subject Marker Choice within the Adnominal Clause: When forming an adnominal clause, the subject within that clause often takes the subject marker
이/가(i/ga) instead of the topic marker은/는(eun/neun). This helps maintain clarity and focuses the overall sentence on the noun being modified by the clause.
- Less Natural:
나는 좋아하는 영화(na-neun joh-ahaneun yeonghwa) (Lit. "As for me, the movie that I like") - More Natural:
내가 좋아하는 영화(nae-ga joh-ahaneun yeonghwa) ✅ (The movie that I like) - Reasoning: Using
이/가for the subject within the modifying clause emphasizes that that subject is performing the action related to the modified noun, without making the subject of the clause the overall topic of the larger sentence. It creates a tighter, more cohesive modifying phrase.
Real Conversations
In contemporary Korean communication, the -는 modifier is indispensable for crafting descriptions that are both nuanced and natural. It allows speakers to pack considerable information into a single phrase, reflecting how native speakers fluidly connect ideas and provide context for nouns. You will find it in every facet of communication, from quick text messages to professional emails.
In casual dialogue, instead of using two separate sentences like 저 사람이 책을 읽어요. 저 사람이 교수님이에요. (That person reads a book. That person is the professor.), a native speaker would seamlessly combine them: 책을 읽는 사람이 교수님이에요. (chaegeul ingneun saram-i gyosunim-ieyo.) – The person reading the book is the professor. This demonstrates both efficiency and a higher level of grammatical integration.
When texting friends, you might use it to ask for recommendations or describe current activities:
- 지금 보고 있는 드라마 진짜 재밌어! (jigeum bogo ittneun deurama jinjjja jaemi-isseo!) – The drama I'm watching right now is really interesting! (해요체, casual)
- 요즘 가는 카페 중에 좋은 곳 있어? (yojeum ganeun kape jung-e joeun got isseo?) – Among the cafes I go to these days, is there a good one? (해요체, casual)
In more formal or professional contexts, such as describing project elements or presenting information, -는 maintains its utility:
- 저희 팀에서 개발하는 시스템은 시장에 큰 영향을 미칠 것입니다. (jeo-hui tim-eseo gaebalhaneun siseutem-eun sijang-e keun yeonghyang-eul michil geos-imnida.) – The system our team is developing will have a significant impact on the market. (합니다체, formal)
- 다음 주에 회의하는 안건은 매우 중요합니다. (daeum ju-e hoe-uihaneun an-geon-eun mae-u jung-yohamnida.) – The agenda item we are discussing next week is very important. (합니다체, formal)
These examples illustrate that -는 is not merely a theoretical grammar point but a practical tool for constructing sophisticated and contextually rich descriptions in various real-world scenarios. It allows you to build a complex understanding of a noun by detailing the action associated with it.
Quick FAQ
-는 and its nuances.하다 verbs (like 공부하다, 운동하다) work with -는?하다 (to do) to a noun. For example, 공부 (study, noun) + 하다 = 공부하다 (to study, action verb). When applying -는, you simply treat 공부하다 like any other action verb: remove 다 to get the stem 공부하, then add -는.공부하는 학생 (gongbuhaneun haksaeng) means "a student who studies." This applies to all 하다 verbs (e.g., 운동하는 사람 – a person who exercises, 요리하는 아빠 – a dad who cooks).-는 compare to -(으)ㄴ (past) and -(으)ㄹ (future) adnominal endings?읽는 책 (ingneun chaek) | The book I am reading / read regularly |-(eu)n) | Past | Action verbs | Completed action | 읽은 책 (ilgeun chaek) | The book I read (and finished) |-(eu)n) | Present | Descriptive verbs | State/quality (e.g., 예쁜) | 예쁜 사람 (yeppeun saram) | A pretty person |-(eu)l) | Future/Prospective | All verbs | Action to be done/potential action | 읽을 책 (ilgeul chaek) | The book I will read / intend to read |-는 with past tense verbs?-는 is strictly for present tense actions (current or habitual). If you want to modify a noun with an action that has already been completed, you must use the past tense adnominal ending -(으)ㄴ for action verbs.제가 먹은 음식 (jega meogeun eum-sik), not 제가 먹는 음식 (which would mean "the food I'm eating").알다 (to know) become 아는 (aneun) instead of 알는 (allneun)?ㄹ irregular rule. The verb stem of 알다 is 알. When this ㄹ-final stem meets an ending that begins with ㄴ, ㅂ, or ㅅ (like -는), the ㄹ drops.알 + -는 becomes 아는. This same principle applies to other ㄹ irregular verbs such as 만들다 (to make) → 만드는, and 살다 (to live) → 사는.-는 and -는 것?-는 is an adnominal ending that modifies a noun, -는 것 (-neun geot) is a nominalizer. It transforms an entire verb phrase into a noun clause, effectively making the action itself the subject or object of a sentence. For example, 책을 읽는 사람 (the person reading a book) uses -는 to modify 사람.책을 읽는 것 (chaegeul ingneun geot) means "the act of reading a book" or "reading a book" as a concept. It turns the action 읽다 into a noun, allowing it to function as a standalone subject or object, as in 책을 읽는 것은 재미있어요. (Reading books is fun.). -는 describes a noun; -는 것 is a noun.Present Tense Modifier Formation
