what does 걸 mean?
I see it quite a lot in Korean but I don't know what it means
I was watching running man and IU said 나는 오빠가 좋은걸
And I have seen it on other things what does it mean?

Question

Answer

-ㄴ 걸  It acts as ending a sentence by attaching to a verb or a adjective in colloquial expression.
나는 오빠를 좋아한다.( a sentence preferred in writing)
나는 오빠가 좋은걸( one of the sentences preferred in colloquial Korean)
I'm into 오빠. I like 오빠

Answer

걸 is from 것을 .. and I've asked it a few weeks ago.. kkkk check my profile! Lol

Answer

나는 오빠가 좋은걸 sounds like 나는 오빠가 좋은걸 (어떡해? what should/could I do about it?) Such subtle emotion is hard to capture and express in words...
