2017년 02월 26일: Help with indirect quotations Hi! It's been awhile! May I ask about the expressions -다고, -자고, -라고, 냐고 하다 forms, since it's a little confusing for me. I've tried to search more about these expressions and -다고 하다 and -라고 하다 are very common. Anyway, on my handbook, here is a summary of what is the usage of these: -다고 하다: Used in an indirect declarative statement. -자고 하다: Used in an indirectly state what is suggested. (Imperative) -라고 하다: Used to indirectly report what is suggested. (also imperative) -냐고 하다: Used in quoting interrogative questions. (Ah, so this is not exactly a question but quoting the question like "He says he is asking you about the missing bag") But just in case, are these expressions interchangeable? Thanks in advance.
