Lesson 51: (으)ㄴ+N

Korean Lesson On Noun Modifier

In this lesson, you will learn about the noun modifier (으)ㄴ. In English, when adjectives are placed before a noun, they modify the meaning of that noun. For example, in the sentence “I bought a blue pencil.“, the adjective ‘blue‘ modifies the noun ‘pencil‘. In Korean, in order to use adjectives to modify nouns, first, you must change the adjective from its dictionary form into the noun modifying form by using (으)ㄴ.

Lesson 51: (으)ㄴ+N

When you look up adjectives in a Korean dictionary, you’ll notice that they are written in the infinitive verb form. For example, if you look up the adjective ‘big‘ you’ll find it written in the verb form as 크다 (to be big). This is why you may sometimes hear adjectives referred to as ‘descriptive verbs’.

In order to use an adjective to modify a noun, first, you need to change this basic verb form of the adjective and change it into the noun modifying form by adding (으)ㄴ. Let’s look at some examples.

크다 = to be big
큰 집 = a big house

예쁘다 = to be pretty
예쁜 꽃 = a pretty flower

작다 = to be small
작은 가방 = a small bag

조용하다 = to be quiet
조용한 사람 = a quiet person

따뜻하다 = to be warm
따뜻한 거 = a warm one/thing

Conjugation Rules

With regular adjectives, if the adjective stem ends in a consonant, 은 is attached, and if the adjective stem ends in a vowel, ㄴ is attached. However, there are exceptions to these rules. When adjectives end in 있다/없다, the ending 는 is used and not (으)ㄴ. See the table below.

Conjugation RuleExamples

<Irregular Conjugations>가깝다 (to be close) → 가까운
낫다 (to be better) → 나은
힘들다 (to be difficult) → 힘든
이렇다 (to be like this) → 이런

Things To Note:

When using more than one adjective in a sentence, only the last adjective includes the noun modifier (으)ㄴ, and the adjectives are connected with 고 (Check Lesson 32 for a review of 고).

싸고 좋은 옷(O) = cheap and nice clothes
싼고 좋은 옷(X)
