  1. Hi, I just found your blog and I love it. You explain everything so well, in fact I finally managed to understand many thing that weren’t clear, so thank you!!! But I have a question, in the phrase
    잠을 잘 수 없어요. = I can’t sleep, I looked at the dictionary it is possible the both 잠 and 자 means “to sleep”? When I tried to translate together it said “sleep well”, could you please explain this, also sorry for any English error, it’s not my first language. Again, thank you a lot !!!! 화이팅 🙂

    1. 안녕하세요. 마리아 씨. Thanks for the reply!

      잠 is a noun for sleep and 자다 is a verb for sleep. So they are often used together as well as just 자다.
      (잠을) 잘 못 잤어요. Can’t sleep.
      (잠을) 잘 자고 싶어요. Want to sleep.

      We have several verbs that are like this such as 춤을 추다 and 짐을 지다.
      잠, 춤, 짐 are nouns that are derived from verbs and they also use with other verbs such as
      잠이 안 와요. Can’t fall asleep.
      춤을 배우고 싶어요. Want to learn dance.
      짐이 무거워요. The stuff is too heavy.
