하러 vs 으러: Comparing Purpose-Expressing Connective Endings

Real-world examples

• ⭕

  학교에 공부하러 갔어요.

  hak-gyo-e gong-bu-ha-reo gass-eo-yo., hak gyo e gong bu ha reo gass eo yo.

  Correct because it combines with the verb '하다' to indicate purpose.

• ❌

  학교에 공부으러 갔어요.

  hak-gyo-e gong-bu-eu-reo gass-eo-yo., hak gyo e gong bu eu reo gass eo yo.

  Incorrect because '공부' is a noun and must use '하러' with '하다'; '공부으러' is wrong.

• ⭕

  친구를 만나러 카페에 갔어요.

  chin-gu-reul man-na-reo ka-pe-e gass-eo-yo., chin gu reul man na reo ka pe e gass eo yo.

  Correct because '러' attaches to the verb stem '만나' to indicate purpose.

• ❌

  친구를 만나하러 카페에 갔어요.

  chin-gu-reul man-na-ha-reo ka-pe-e gass-eo-yo., chin gu reul man na ha reo ka pe e gass eo yo.

  '만나다' is not '하다', so '하러' cannot be used here.

• ⭕

  운동하러 공원에 갑니다.

  un-dong-ha-reo gong-won-e gap-ni-da., un dong ha reo gong won e gap ni da.

  Appropriate because it combines with '운동하다' to express purpose.

• ❌

  운동으러 공원에 갑니다.

  un-dong-eu-reo gong-won-e gap-ni-da., un dong eu reo gong won e gap ni da.

  Incorrect because '운동' is a noun and must use '하러' with '하다'.

• ⭕

  편지를 보내러 우체국에 갔어요.

  pyeon-ji-reul bo-nae-reo u-che-guk-e gass-eo-yo., pyeon ji reul bo nae reo u che guk e gass eo yo.

  Correct as '러' attaches to the verb stem '보내' to indicate purpose.

• ❌

  편지를 보내하러 우체국에 갔어요.

  pyeon-ji-reul bo-nae-ha-reo u-che-guk-e gass-eo-yo., pyeon ji reul bo nae ha reo u che guk e gass eo yo.

  '보내다' is not '하다', so '하러' cannot be used here.
