This is the 44th most frequent Korean word.
할
"할" means "to do" or "will do" depending on context.
In this sentence, '할' is used as an attributive form of the verb '하다', meaning 'to do'. It modifies the noun '일' (work) to indicate tasks or duties that need to be done.
나는 할 일을 모두 끝냈어요.
I have finished all the work I had to do.
In this example, '할' again serves as the attributive form of '하다', linked to '계획' (plans) to describe future actions or intentions.
내일 할 계획은 무엇인가요?
What are your plans for tomorrow?
Here, '할' is part of the phrase '할 수 있다', which translates to 'can do'. It expresses the potential action to be performed.
