하라

In a sentence

• 그는 나에게 그것을 하라고 말했다.

  He told me to do that.

  In this sentence, '하라' is used as a command form derived from the verb '하다' (to do), combined with '-라고', which indicates reporting or quoting a directive.

• 그가 하라니까 하자.

  Since he says to do it, let's do it.

  Here, '하라' is again the command form of '하다', used in a context to show someone's directive or suggestion, inviting compliance or agreement.

• 할 일이 너무 많아서 무엇을 먼저 하라 할지 모르겠다.

  There is so much to do that I don't know what to be told to do first.

  In this case, '하라 할지' uses '하라' within a reported speech context, denoting the act of instructing or commanding.
