Can ~고 be dropped in the ~는다고 하다 (quoting) construction ? In some Korean sentences I read, in what seems to be quotations, "~고" is missing. Here is an example : "어쩐지 요즘 들어서 많이 달라졌다 했어" "No wonder that when I listened these days I heard that you had changed a lot." In general, when part of a construction can be dropped, my Korean textbook mentions it, but it doesn't talk about the possibility of dropping "고" in the ~는다고 하다 construction used to quote something. So I just wanted to make sure, in the sentence above, is "많이 달라졌다 했어" a quotation, equivalent to "많이 달라졌다고 했어" ? Can you drop ~고 in a quotation in all contexts or is it reserved to some forms of speech, maybe a bit informal ? Thank you for your answers !
