-(으)ㅁ

Nominalizing Ending

Level 3

Attach -ㅁ/음 to a verb or adjective stem to turn it into a noun. It's similar to adding '-ness' or '-ing' in English, but is often used for more abstract concepts, states, or facts.

How It Works

The ending -ㅁ/음 is a crucial tool for creating nouns from verbs and adjectives, a process called nominalization. It's particularly common in written Korean, titles, and formal speech to express concepts, states, or facts.

Conjugation Rules:
1. Vowel Stem + -ㅁ: If the verb/adjective stem ends in a vowel, attach -ㅁ.
- 자다 (to sleep) → 잠 (sleep)
- 기쁘다 (to be happy) → 기쁨 (joy, happiness)

2. Consonant Stem + -음: If the stem ends in a consonant, attach -음.
- 먹다 (to eat) → 먹음 (eating, the act of eating)
- 좋다 (to be good) → 좋음 (goodness)

3. ㄹ Stem → Drop ㄹ + -ㅁ: If the stem ends in ㄹ, the ㄹ is dropped before adding -ㅁ.
- 살다 (to live) → 삶 (life)
- 만들다 (to make) → 만듦 (making, creation)

-ㅁ/음 vs. -기
While both are nominalizers, they have different nuances:

  • -ㅁ/음: Often refers to a concrete result, a state, a fact, or an abstract concept. It feels more static and is common in formal or literary contexts. Think of it as creating a standalone noun.
  • -기: Often refers to the action or process itself. It feels more dynamic and is common in everyday speech and in various grammatical patterns like -기 때문에 (because of doing) or -기 시작하다 (to start doing).

For example, '꿈을 이룸' means 'the realization of a dream' (a fact/result), while '꿈을 이루기' means 'realizing a dream' (the process/act).

Examples (5)

  1. 그의 죽음은 모두에게 큰 슬픔이었다.

    His death was a great sadness to everyone.

    Word by Word: His death-topic marker everyone-to big sadness-was.

    Here, 죽다 (to die) becomes 죽음 (death) and 슬프다 (to be sad) becomes 슬픔 (sadness). Both are nominalized using this pattern.

  2. 도움이 필요하시면 연락주세요.

    If you need help, please contact us.

    Word by Word: Help-subject marker if you need contact please give.

    돕다 (to help) is nominalized to 도움 (help, assistance). This form is very common on signs and in official announcements.

  3. 저는 그림 그리기를 좋아하지만, 좋은 그림을 보는 것도 좋아해요.

    I like drawing pictures, but I also like looking at good pictures.

    This example contrasts the two nominalizers. '그리기' (-기) refers to the act of drawing. '그림' is a standalone noun that historically comes from 그리다 + -ㅁ, referring to the result of drawing (a picture).

  4. 최선을 다했음에 후회는 없습니다.

    I have no regrets in having done my best.

    Word by Word: Best-object marker did-in regret-topic marker do not exist.

    This shows a more advanced usage where the past tense -았/었- is combined with -음 to nominalize a past action: 다했다 → 다했음.

  5. 인생은 앎과 모름의 연속이다.

    Life is a continuation of knowing and not knowing.

    Word by Word: Life-topic marker knowing-and not knowing-of continuation-is.

    알다 (to know) becomes 앎 (knowledge/knowing) and 모르다 (to not know) becomes 모름 (not knowing). This demonstrates the pattern's use for abstract concepts.

Common Mistakes

  • Using -ㅁ/음 when -기 is more natural, especially for ongoing activities or hobbies.

    Not Quite제 취미는 책 읽음입니다.
    Better제 취미는 책 읽기입니다.

    When talking about a hobby or the general act of doing something, -기 is the standard choice. '읽음' sounds overly formal and static, as if referring to a single, completed act of reading rather than the activity itself.

  • Forgetting to drop the ㄹ from stems before adding -ㅁ.

    Not Quite그것을 만들음에 시간이 오래 걸렸다.
    Better그것을 만듦에 시간이 오래 걸렸다.

    When a verb or adjective stem ends in ㄹ, the ㄹ is dropped before attaching -ㅁ. So, 만들다 becomes 만듦, not 만들음.
