First of all, yes, 하고 and 다고 are two different things. 1. 하고 - 하고 is one of the many verb forms. Simply put, it's translated as "--- and," 원하다 to want. 원하고 to want and... 말하다 to say. to speak 말하고 to say and... to speak and... - For example, 나는 아이스크림을 *원하고* 너는 쿠키를 원한다. (I want ice cream *and* you want cookie.) 나는 *말하고* 너는 듣는다. (I talk *and* you listen.) - However, notice that "~하고 있다" is an idiomatic expression for "to be doing something (right now)" (present progressive) and "~하고 싶다" is an idiomatic expression for "to hope to do something." So in these two cases, "하고" has nothing do with its original meaning of "and..." - For example, 나는 Robert와 *말하고 있다.* (I'm talking with Robert (*right now*)) 나는 한국어로 *말하고 싶다.* (I *hope* to talk in English.) ------------------------ 2) 다고 - 다고 is used for "indirect quotes." In English, you guys use "that." - For example, 그는 나에게 한국에 *간다고* 말했다. He told me *that* he is going to Korea. 나를 *사랑한다고* 말해. Say *that* you love me. ------------ Hope my explanation clarified your question. 좋은 하루 되세요
