-오/소

Formal Archaic Ending

Level 5Sounds Like o so

-오/소 is an old-fashioned formal sentence ending, similar to -ㅂ/습니다, used for statements and commands.

How It Works

-오/소 is a formal sentence ending that belongs to an older style of Korean, often referred to as the 하오체 speech level. While not used in daily conversation today, it is essential for understanding historical dramas (사극), literature, proverbs, and certain official or ceremonial texts. Using it in modern speech would sound theatrical or like you are quoting a historical figure.

Conjugation Rules:
1. Verb/Adjective stem ends in a vowel or ㄹ: + -오
- 가다 (to go) → 가 + 오 → 가오
- 오다 (to come) → 오 + 오 → 오오
- 살다 (to live) → 사 + 오 → 사오 (ㄹ is dropped)
- 이다 (to be) → 이 + 오 → 이오

2. Verb/Adjective stem ends in a consonant (except ㄹ): + -소
- 먹다 (to eat) → 먹 + 소 → 먹소
- 좋다 (to be good) → 좋 + 소 → 좋소
- 있다 (to exist) → 있 + 소 → 있소

Usage:

  • Declarative: It makes a formal statement, much like the modern -ㅂ/습니다.
  • Imperative: When combined with the honorific -시-, it forms -(으)시오, which is a formal, archaic command. This is one of its most common appearances. For example, '하시오' (Do it) or '앉으시오' (Sit down).

Think of -오/소 as the historical predecessor to the modern formal -ㅂ/습니다 style. Its presence immediately signals an old-fashioned, solemn, or historical setting.

Examples (5)

  1. 내일 다시 오시오.

    Come again tomorrow.

    Word by Word: Tomorrow again come.

    This is an example of the imperative form -(으)시오. It's a formal command you might hear from an elder or a person of high status in a historical setting. 오다 + -시오.

  2. 이것은 내 것이 아니오.

    This is not mine.

    Word by Word: This thing is my thing is not.

    A declarative sentence using the copula 아니다. The stem 아니- ends in a vowel, so -오 is attached. This sounds very literary or historical.

  3. 그대의 뜻이 정 그렇다면 내 허락하겠소.

    If that is truly your will, then I shall permit it.

    Word by Word: Your will if really so, my permission will do.

    A complex sentence typical of historical dialogue. The final verb, 허락하겠다, has a stem ending in a consonant (허락하겠-), so -소 is added.

  4. 세상사란 알 수 없는 법이오.

    The ways of the world are unknowable.

    Word by Word: World affairs are cannot know law is.

    This sentence has a philosophical and poetic tone. It uses the pattern with the copula 이다 (법이다 -> 법이오).

  5. 걱정하지 마시오. 모든 것이 잘될 것이오.

    Do not worry. Everything will be fine.

    Word by Word: Worry do not. Everything well will become thing is.

    This example shows both the imperative (마시오 from 말다) and declarative (것이오 from 것이다) forms in one dialogue, giving it a reassuring but formal and old-fashioned feel.

Common Mistakes

  • Using -오/소 in modern daily conversation.

    Different Meaning선생님, 점심 드셨소?
    Better선생님, 점심 드셨어요?

    -오/소 is an archaic ending. Using it to speak to a teacher in a modern context would sound bizarre and theatrical, as if you were acting in a play. Use standard polite endings like -아/어요 or the formal -ㅂ/습니다 instead.
