- 다니까요
→ It is a combined form in which '-니까요' is added to an indirect speech form '-다고 하다' and then '고 하' is omitted. It is used when the other party has no response or is doubtful, so the speaker emphasizes his/her idea or his/her opinion. Various forms of indirect speech are able to be used.
Example:
1. 금방 시작한다니까요. It will start in no time.
2. 어제는 아파서 도저히 갈 수 없었다니까요.
I was sick yesterday, so I just couldn't make it.
