Usage notes

• Usually in the first sense, 으로 (-euro) is more indirect as it expresses going towards a certain direction or a certain location. 에 (-e) on the other hand, expresses a direct location, which is similar to 를 (-reul).
  • In this directional sense, only 으로 (-euro) can be used with expressions ending with 쪽 (jjok). Using 에 (-e) in such case would result in a locative sense.
