"운동장"

Translation: Sports field

[IzebeRucke]

Couldn't this also be translated to "gym"?

[wintertriangles]

This would be outdoors, so you'd have to use 체육관 for a school gym, and the Konglish 헬스장 for a workout-type gym (or for the purists, 단련실!)

[-kcdhari-]

Could this also mean "playground"?

[Ivitcyex]

This is more the big open field at a school. Naver gives 노리터 as the kind of playground you find at parks, with equipment for kids to play on.

[SeanFogart4]

놀이터 in the dictionaries: https://en.wiktionary.org/wiki/%EB%86%80%EC%9D%B4%ED%84%B0 -- from 놀이 = game/(relaxing/entertaining) play, and 터 for "ground" . . .
