-음/ㅁ
Nominalizing Ending
-음/ㅁ is a grammar pattern that changes a verb or adjective into a noun. Think of it like adding '-ness', '-ing', or '-tion' in English. It's often more formal than the other nominalizer, -기.
How It Works
-음/ㅁ is a key nominalizing suffix in Korean, alongside -기. While both turn verbs and adjectives into nouns, they have different nuances and are used in different contexts.
How to Use:
1. Attach -음 to stems ending in a consonant (e.g., 먹다 → 먹음, 좋다 → 좋음).
2. Attach -ㅁ to stems ending in a vowel (e.g., 가다 → 감, 예쁘다 → 예쁨).
3. For stems ending in ㄹ, the ㄹ is kept and -ㅁ is added, merging into the ㄻ cluster (e.g., 살다 → 삶, 만들다 → 만듦, 알다 → 앎).
Nuances and Usage:
- Formality and Written Language: -음/ㅁ is frequently used in formal writing, official notices, signs, and academic texts. It can sound stiff or overly formal in casual conversation. For example, a sign might say '금연 구역임' (This is a no-smoking area).
- Abstract Concepts & Specific Instances: It often refers to an abstract concept, a specific instance of an action, or a completed fact. For example, '죽음' (death) is an abstract concept derived from '죽다' (to die). '그가 왔음' means 'the fact that he came'.
- Standalone Nouns: Many common nouns in Korean are formed with this ending and are now established vocabulary words. Examples include: 꿈 (dream), 잠 (sleep), 웃음 (laughter), 삶 (life), 죽음 (death), 믿음 (faith/trust).
Comparison with -기:
While -음/ㅁ often refers to a static fact or concept, -기 typically refers to the action or process itself. This is why -기 is used in patterns that describe the progression of an action, like '-기 시작하다' (to start doing) or '-기 어렵다' (to be difficult to do).

- 저는 그가 옳았음을 깨달았어요.
I realized that he had been right.
Word by Word: I him was right-(fact) realized.
Here, '옳았음' turns the past tense adjective '옳았다' (was right) into a noun phrase, 'the fact that (he) was right', which then becomes the object of the verb '깨달았어요' (realized).
- 삶과 죽음은 누구에게나 공평하다.
Life and death are fair to everyone.
Word by Word: Life and death to everyone is fair.
'삶' (life) comes from '살다' (to live) and '죽음' (death) comes from '죽다' (to die). These are common nouns formed with this grammar pattern.
- 도서관에서는 정숙해야 함.
(Notice) You must be quiet in the library.
Word by Word: In the library must be quiet.
This is a typical example of -음/ㅁ used in written notices or rules. It creates a formal, declarative statement. '정숙해야 함' means 'the requirement to be quiet'.
- 그녀의 아름다움에 모두가 놀랐다.
Everyone was surprised by her beauty.
Word by Word: Her beauty-at everyone was surprised.
The adjective '아름답다' (to be beautiful) becomes the noun '아름다움' (beauty).
- 회의가 곧 시작됨을 알려드립니다.
We are informing you that the meeting will begin shortly.
Word by Word: Meeting soon begins-(fact) we inform you.
A very formal announcement. '시작됨' (the beginning/the fact that it begins) acts as the noun object of '알려드립니다' (we inform you).
Common Mistakes
Using -음/ㅁ instead of -기 with verbs that describe the phase of an action (like 'start', 'finish', 'easy', 'difficult').
Not Quite한국어 공부함을 시작했어요.Better한국어 공부하기를 시작했어요.The pattern 'to start doing something' is always '-기 시작하다'. -음/ㅁ creates a noun representing a fact or concept, which doesn't fit grammatically with a verb like '시작하다' (to start). Use -기 for actions that are the object of verbs like 'start', 'stop', 'like', 'hate', etc.

- -는 것Thing of -ing
This is another way to create a noun phrase from a verb. While -음/ㅁ creates a single noun, -는 것 creates a noun clause ('the act of doing X' or 'the fact that X'). -는 것 is extremely common in everyday conversation.
- -ㄴ/은Adjective Noun Modifier
-음/ㅁ creates a noun (e.g., 아름다움 - beauty), whereas -ㄴ/은 is a noun modifier that describes a noun (e.g., 아름다운 사람 - a beautiful person). Both are derived from adjectives but serve different grammatical functions.
- Verb stems
This is the fundamental building block. The -음/ㅁ ending attaches directly to the verb or adjective stem.
