다니까

I'm telling you it's like that

Repeats something you have already said, with the impatience of not being believed: I'm telling you this is fun, there really was nothing to do back then, she's even prettier than the campus belle, it caught me off guard. It is built from the reporting ending plus 'because', so literally it is 'because I said so'. It attaches to descriptions and past forms; ㄴ다니까 is the version for present-tense action verbs, and 라니까 is the one for nouns.

Register: casual, insistent
