Question about 수
안녕하세요!
I was watching a Korean short story just now, and there was this sentence "저는 기다릴 수 없어요". I more or less understand what this sentence means, but I did start to wonder about the meaning of 수 in this sentence. In the dictionary, there are different meanings for it.
My question is, why is 수 in this sentence, and what does it stand for?
감사합니다!
Edit: I got the answer to my question. Thank you, everyone, for answering!
