1. What does it mean?
오운완 abbreviates 오늘 운동 완료. It is a compact way to mark finishing exercise, often in a workout log, a caption, or a message to a friend.
Also written or said as 오늘 운동 완료, 오늘운동완료
2. The nuance
It records completion, not a particular duration, intensity, or fitness result. A short routine can count for the speaker just as a long session can. The full phrase explains the meaning more clearly than trying to translate each syllable separately.
3. Examples
“점심시간에 가볍게 걷고 오운완 기록을 남겼어.”
I took a light walk at lunchtime and logged today's exercise as done.
“비가 와서 집에서 스트레칭으로 오운완했어.”
It was raining, so I finished today's exercise with stretching at home.
