을/를(eul, reul)

을/를 are particles that mark the object of a verb in Korean.

The nuance

1. 을/를 mark the direct object of a verb. 2. Attach '을' after nouns ending with a consonant, and '를' after nouns ending with a vowel. 3. They clarify the target of an action. 4. They differ from subject markers 은/는 and 이/가. 5. Used to emphasize the object in questions or commands.

Real-world examples

  • 책을 읽어요.

    chaek-eul ik-eo-yo., chaek eul ik eo yo.

    책 ends with a vowel sound, so '를' is used to mark the object.

  • 사과를 먹어요.

    sa-gwa-reul meok-eo-yo., sa gwa reul meok eo yo.

    사과 ends with a vowel, so '를' marks the object.

  • 영화를 봅니다.

    yeong-hwa-reul bop-ni-da., yeong hwa reul bop ni da.

    영화 ends with a vowel, so '를' is used.

  • 밥을 먹었어요.

    bap-eul meok-eoss-eo-yo., bap eul meok eoss eo yo.

    밥 ends with a consonant, so '을' marks the object.

  • 책이 읽어요.

    chaek-i ik-eo-yo., chaek i ik eo yo.

    '책이' marks the subject, not the object, so it's incorrect here.

  • 사과가 먹어요.

    sa-gwa-ga meok-eo-yo., sa gwa ga meok eo yo.

    '사과가' marks subject; '사과를' is correct for object.

  • 밥를 먹었어요.

    bap-reul meok-eoss-eo-yo., bap reul meok eoss eo yo.

    '밥' ends with consonant, so '을' is required, not '를'.

  • 영화를 봐요.

    yeong-hwa-reul bwa-yo., yeong hwa reul bwa yo.

    영화 ends with vowel, so '를' is correct.
