Grammar
-다는 것
the fact that…
Form
Present verb + -ㄴ/는다는 것; adjective + -다는 것 — “the fact that…”.
Function
Turns a declarative proposition into a nominalized content clause that can be confirmed, known or denied. The form depends on predicate type.
Why this form?
-(으)ㄴ/는 것 — “the act of / what…”: directly nominalizes an event without the declarative framing of -다고.
Forms not to confuse
-(으)ㄴ/는 것
그가 온 것을 알아요. — I know that he came.
Examples
저희 모두가 기억이 없다는 게 확인됐네요. — It has been confirmed that none of us has any memories.
이 일이 중요하다는 걸 알아요. — I know that this matter is important.
