Verb and Adjective Noun Modifiers in Korean

In Brief

Korean places a verb or descriptive verb before the noun it describes: 먹는 사람 is “a person who eats/is eating,” and 예쁜 꽃 is “a pretty flower.” Action verbs normally use -는 for present or habitual action, -(으)ㄴ for completed action, and -(으)ㄹ for future, intended, or possible action. Descriptive verbs—the Korean words commonly called adjectives—normally use -(으)ㄴ for a present quality.

Overview

A noun is a word for a person, place, thing, or idea, such as 사람 “person,” 책 “book,” or 약속 “appointment.” A modifier gives more information about that noun. English can put an adjective before a noun (“a pretty flower”) or a relative clause—a short clause describing a noun—after it (“the book that I bought”). Korean puts both kinds of information before the noun.

This noun-modifying form is called 관형형 in Korean. It lets you expand a simple statement such as 친구가 와요 “A friend is coming” into a noun phrase such as 오는 친구 “the friend who is coming.” Korean needs no separate relative word equivalent to English “who,” “that,” or “which.” The form attached to the verb does the grammatical work.

At A2, the essential task is to distinguish action verbs from descriptive verbs and choose the core ending. This pattern is indispensable: it appears in descriptions, questions, signs, menus, plans, and expressions built with 것 “thing.” Later, you will meet finer distinctions involving remembered events, ongoing states, and implied information.

How It Works

1. Put the complete modifying clause before the noun

The basic order is:

Structure	Example	Natural English meaning
modifier + noun	예쁜 꽃	a pretty flower
verb clause + noun	제가 어제 산 책	the book that I bought yesterday
time/place/object + modifier + noun	한국에서 일하는 사람	a person who works in Korea

English-speaking learners often want to begin with the noun: “the book + that I bought.” Reverse that habit in Korean. Build 제가 어제 산 “that I bought yesterday” first, then add 책 “book.” Particles inside the modifying clause stay where they normally belong: 제가 marks the buyer, while 책 is the described noun and does not take an object particle inside that clause.

2. Find the stem

Remove -다 from the dictionary form to find the stem (the base to which an ending is attached):

Dictionary form	Stem	Type	Meaning
먹다	먹-	action verb	to eat
가다	가-	action verb	to go
만들다	만들-	action verb	to make
예쁘다	예쁘-	descriptive verb	to be pretty
작다	작-	descriptive verb	to be small

3. Action verbs

For the beginner rule, choose the form according to how the action relates to the noun.

Relationship	Ending	Vowel-ending stem	Consonant-ending stem	Example
present, ongoing, or habitual	-는	-는	-는	가는 버스, 먹는 사람
completed or past	-(으)ㄴ	-ㄴ	-은	간 버스, 먹은 음식
future, intended, expected, or possible	-(으)ㄹ	-ㄹ	-을	갈 버스, 먹을 음식

The labels “past,” “present,” and “future” are useful shortcuts, but they describe the action relative to the situation being discussed, not always the calendar time of the whole sentence.

• 매일 운동하는 사람 — a person who exercises every day (habit)
• 어제 운동한 사람 — a person who exercised yesterday (completed)
• 내일 운동할 사람 — a person who will exercise tomorrow (expected/intended)

With an action verb whose stem ends in ㄹ, drop that ㄹ before -ㄴ or -ㄹ:

Dictionary form	Completed	Future/intended
만들다	만든 케이크	만들 케이크
살다	산 집	살 집
열다	연 문	열 문

For the present action form, keep the ㄹ and add -는: 만드는 사람, 사는 곳, 여는 시간.

4. Descriptive verbs (“adjectives”)

Korean words such as 예쁘다 “to be pretty” and 작다 “to be small” behave like verbs at the end of a sentence: 꽃이 예뻐요 “The flower is pretty.” Before a noun, their ordinary present modifier is -(으)ㄴ.

Stem ending	Formation	Example
vowel	stem + -ㄴ	크다 → 큰 집
consonant	stem + -은	작다 → 작은 집
하다	한	조용하다 → 조용한 방

Several common conjugation changes also apply:

Pattern	Dictionary form	Noun modifier	Meaning
ㅂ irregular	춥다	추운 날	a cold day
ㅂ irregular	아름답다	아름다운 도시	a beautiful city
ㄹ drop	길다	긴 길	a long road
ㄹ drop	멀다	먼 곳	a faraway place
regular consonant	좋다	좋은 생각	a good idea

Do not attach present -는 to an ordinary descriptive verb: 예쁘는 꽃 is incorrect. Two extremely common words that look descriptive but take -는 are 있다 and 없다: 있는 사람 “a person who is there/has it” and 없는 시간 “time one does not have.” Compounds ending in them follow the same pattern: 맛있는 음식, 재미없는 영화.

A descriptive verb can also use -(으)ㄹ when the quality is expected, hypothetical, or future: 좋을 날 “a day that will be good,” 필요할 물건 “an item that will be needed.” This is useful, but the basic A2 contrast remains: present quality 좋은, expected quality 좋을.

5. The copula 이다

When a noun identifies or classifies another noun, 이다 becomes 인:

• 학생인 사람 — a person who is a student
• 제 고향인 부산 — Busan, which is my hometown

The negative 아니다 becomes 아닌: 학생이 아닌 사람 “a person who is not a student.” Notice that 아니다 normally keeps the subject particle 이/가 before it.

6. What role does the described noun have?

The noun after the modifier may be the doer, receiver, location, time, or another understood part of the action. Korean usually leaves that role implicit.

Phrase	Relationship	Meaning
노래하는 사람	사람이 노래하다	a person who sings
제가 읽은 책	제가 책을 읽다	the book that I read
친구를 만날 카페	카페에서 친구를 만나다	the café where I will meet a friend
한국에 온 날	그날 한국에 오다	the day when I came to Korea

English chooses “who,” “that,” “where,” or “when.” Korean uses the same pre-noun structure and lets meaning supply the relationship.

7. 것: “thing,” “one,” or an abstract fact

것 is a dependent noun—a noun that commonly relies on preceding information. With these modifiers, it creates very frequent expressions:

Form	Core meaning	Example
-는 것	doing; what someone does	읽는 것을 좋아해요. “I like reading.”
-(으)ㄴ 것	what was done; the completed one	제가 만든 것이에요. “It is the one I made.”
-(으)ㄹ 것	something to do/use; what will happen	먹을 것이 없어요. “There is nothing to eat.”

In conversation, 것이 often contracts to 게, and 것은 to 건: 제가 찾는 게 이거예요 “This is what I’m looking for.” Learn the full forms first so the contractions remain transparent.

Common Mistakes

Using -는 with an ordinary descriptive verb

• Wrong: 예쁘는 꽃
• Right: 예쁜 꽃
• Why: Present action verbs use -는, but ordinary descriptive verbs use -(으)ㄴ for a current quality.

Treating an action verb like a present adjective

• Wrong: 먹은 사람 for “the person who is eating”
• Right: 먹는 사람
• Why: 먹은 사람 means “the person who ate/has eaten.” Use -는 for an action in progress or a habit.

Keeping English relative-clause order

• Wrong: 책 제가 어제 산
• Right: 제가 어제 산 책
• Why: The whole describing clause comes before the noun in Korean. There is no separate word for “that” here.

Adding a particle to the missing role inside the clause

• Wrong: 제가 책을 읽은 책
• Right: 제가 읽은 책
• Why: The final noun 책 already fills the understood object position of 읽다. Do not state it twice inside the modifier.

Applying the ordinary adjective rule to 있다 and 없다

• Wrong: 있은 사람, 없은 문제, 맛있은 음식
• Right: 있는 사람, 없는 문제, 맛있는 음식
• Why: 있다, 없다, and compounds ending in them use -는 in their present noun-modifying forms.

Forgetting ㄹ deletion

• Wrong: 만들은 음식, 길은 길
• Right: 만든 음식, 긴 길
• Why: A stem-final ㄹ drops before noun-modifying -ㄴ. Other forms may retain it: 만드는 음식.

Usage Notes

The English translation is not always a literal guide to Korean tense. 입을 옷 may be “clothes to wear,” “the clothes I will wear,” or “clothes suitable for wearing,” depending on context. Likewise, 가는 길 can mean “the way there” or “while on the way,” not only the awkwardly literal “the road that goes.” Learn common noun phrases as complete units.

Korean often omits a subject when context identifies it. 어제 산 책 can mean “the book I bought yesterday,” “the book she bought yesterday,” or simply “the book bought yesterday.” Add 제가, 친구가, or another subject only when it is useful or contrastive.

Modifiers do not carry a polite sentence ending. Politeness appears on the final predicate: 선생님이 추천하신 책이에요 “It is the book the teacher recommended.” Here -(으)시- honors the teacher inside the modifier, while -이에요 makes the whole sentence polite.

Beyond the Basics

You do not need to master all of the following at A2, but these forms explain contrasts you will often see.

-던 and -았/었던

-던 presents a past action or state as remembered, ongoing, repeated, or not viewed from its endpoint. 제가 자주 가던 카페 is “the café I used to go to often.” 읽던 책 is “the book I was reading,” often implying that the reading was in progress.

-았/었던 looks back on a completed past event or a state that no longer holds: 지난달에 읽었던 책 “the book I read last month,” 어렸을 때 살았던 집 “the house where I lived as a child.” In everyday use, it can overlap with simple -(으)ㄴ, but it adds a stronger sense of recollection or past distance.

Relative time rather than absolute time

The modifier’s form is interpreted in relation to the main situation:

• 내일 출발할 때 가져갈 책을 샀어요. — I bought a book to take when I leave tomorrow.

The main verb 샀어요 is past, while 출발할 and 가져갈 point forward from that purchase or toward the planned event. Do not force every ending to match the tense of the final verb.

Ambiguity can be normal

Because Korean has no relative pronoun and often omits participants, one phrase may allow more than one reading. 친구가 소개한 사람 usually means “the person whom my friend introduced,” but context must identify whom the friend introduced the person to. Natural Korean supplies only information that the conversation needs.

Longer modifiers

A modifier can contain negation, aspect, honorifics, and embedded grammar:

• 아직 읽지 않은 책 — a book I have not read yet
• 지금 공부하고 있는 학생 — a student who is studying now
• 선생님께서 말씀하신 내용 — what the teacher said
• 내일 비가 올 것 같은 날씨 — weather that looks as though it will rain tomorrow

The last example leads into -(으)ㄹ 것 같다, a later pattern for supposition. Even when the modifier grows long, its noun still comes at the end.

Practice Tips

1. Build three-way sets. Choose five action verbs and pair each with one noun: 읽는 책 / 읽은 책 / 읽을 책. Say how the meaning changes instead of memorizing the endings in isolation.
2. Work backward from the noun. In a Korean sentence, underline the noun, then bracket everything immediately before it that answers “which one?” For 제가 어제 도서관에서 빌린 책, identify 책 first and then unpack the modifier.
3. Describe your real surroundings. Make short phrases such as 마시는 커피, 어제 산 가방, 주말에 볼 영화, and 조용한 방. Personal examples make the time contrast easier to remember.

Related Concepts

• Prerequisite: Descriptive Verbs (Adjectives) — review how Korean quality words behave and conjugate.
• Next step: Degree/Extent Expressions — expand descriptions by expressing how much or to what extent.
• Next step: Supposition -(으)ㄹ 것 같다 — combine a future noun modifier with 것 같다 to express what seems likely.
• Later connection: Nominalization -기/-음 — compare noun-modifying clauses with forms that turn an action or state itself into a noun-like expression.
