TOPIK 3-4

A-다니까(요)usage

I’m telling you!

Repeat a statement when the listener does not believe or accept what you have said. It can also add strong certainty to something you are saying for the first time, stressing that it really is true. It is often used to reassure someone who keeps apologizing or worrying, as in 괜찮다니까요. This spoken form can convey frustration, so it is mainly used with people you are close to. Soften your tone when speaking to someone senior.
