About んだって

When used at the end of sentences, だって often expresses something that has been heard by the speaker. This particular use of だって will always be paired with ん or なん.
As だって is a grouping of the auxiliary verb , and the adverbial particle って, なんだって primarily expresses the following:
なん - Presents an explanation.
だ - Determines something to be true.
って - An abbreviation of と()って 'is said' or と(おも)って 'is thought'.
In this way, it translates quite similarly to 'it is that (A) was said/thought'. Realistically though, it is used in the same way as 'I heard that (A)', or 'it's thought that (A)'.
  • サクラちゃん来年(らいねん)結婚(けっこん)するんだって。うらやましいね。
    I heard that Sakura-chan is going to get married next year. I am jealous, aren't you?
  • タケル(くん)(あたら)しいおもちゃ(ほし)しいんだって。どうしよう?()てあげる
    I heard that Takeru-kun is wanting a new toy. What should we do? Should we buy it for him?
  • あの博士(はかせ)(すご)(こと)()っているように聞こえるけど(じつ)()ていること全部(ぜんぶ)適当(てきとう)んだって
    It sounds like that scientist is saying some amazing stuff, but I heard that everything he says is hot air.
  • タクミさんはレスラーみたいな(からだ)しているけど()なスポーツはフィギュアスケートなんだって
    Takumi-san has a body like a wrestler, but I heard that his favorite sport is figure skating.
Caution
なんだって usually comes across as being quite casual, so is best used in conversations with friends.

              Are んだって and だって interchangeable in their meaning “I heard”? When exactly do I have to use one or the other?

            • mrnoone

              mrnoone

              @Anthropos888
              Hey
              Main difference is だって can only follow nouns, while んだって can also follow adjectives and verbs.
              Plus んだって has more emphasis.

              Another difference is that だって can mean because when used on the begining of the sentence. んだって cannot.
