～(んだ)って

About

んだって, or simply (だ)って, can be used at the end of a sentence to express the speaker's frustration at having to repeat themselves.

Since ～(んだ)って at the end of a sentence can also indicate hearsay, context should be used to determine which meaning is at play.

～んだって can attach directly to casual form verbs/い-adjectives, or to nouns/な-adjectives using な or じゃない.

E.g. 今いま出発しゅっぱつしないと間まに合あわないんだって！ "I said, if we don't leave now, we're not gonna make it!"

E.g. 後あとで片付かたづけるって！ "I said I'll clean later!"

E.g. そこ痛いたいって！ "I said that (spot) hurts!"

E.g. マイクのことは好すきじゃないんだって。 "I said, I don't like Mike."
