Today I had an Italki lesson which made both of us laugh so many times. One of those moments was when reviewing a bit of vocabulary and she asked me how to say “athlete” in Korean. I confidently replied: 선수.
Only, when 선수 is on its own it has the same meaning as 바람둥이… a player. A womanizer.
You have to combine it with some word related to sports for it to get the meaning of athlete.
운동선수 athlete (sport is unspecified)
축구선수 football player
