だって・ んだってI heard; but, because; even
だって is three different things in conversation, and where it stands usually tells you which: at the end of a sentence, "I heard"; at the start, "but" or "because" in your own defense; after a noun, "even".
at the end: I heard
I hear Yamada's arriving around seven.
at the start: but, because
"Aren't you taking an umbrella?" "But it's sunny."
I heard
Plain form + んだって
A noun or な-adjective takes な: 休みなんだって, 静かなんだって. Or it takes だって alone: 休みだって.
But, because
だって、 + your reason
The reason often ends in んだ, んだよ or んだもん.
Even
Noun + だって
The spoken でも.
At the end: I heard
You tell a friend or your family some news that someone told you. Who it came from often goes first: 〜が言ってたけど, 〜に聞いたんだけど.
The clerk said this model is lighter than the previous one.
The teacher said there's no class next week.
I heard from my mother that twelve people are going on the trip.
With the voice going up, it asks whether the news is true, often of the person it is about.
I hear you're getting married next month?
Yeah. Who told you?
Said with force, it isn't news but your own words again: "I'm telling you".
Believe me. It's true, I'm telling you.
At the start: but, because
Someone blames you, tells you what to do or asks why, and you push back with your reason. It also backs up something you have just said yourself. English picks "but" or "because"; だって is both at once. It sounds defensive, often sulky, so it stays with family and friends.
Come on, start your homework.
But I'm still eating dinner.
"Why did you turn it down?" "Because it was far too sudden."
I'm not going. It's cold, that's why.
もん at the end makes it sound childish, often on purpose.
It isn't a neutral "because". At work it is answering back.
Sounds odd: 遅れてすみません。
Sorry I'm late. But the train had stopped.
Leave it out: 電車が止まっていたんです.
After a noun: even
子どもだって is a more spoken 子どもでも, "even a child". After 私 or a name it is often a protest: "me too, you know". だれだって is "anyone".
Even grown-ups feel like crying sometimes.
I wanted to go too, you know.
Close neighbours
たって・だってN3
The spoken でも and ても: "even" after a noun, and "even if" on a verb, where 読んだ gives 読んだって.
No matter how many times you read it, this explanation won't make sense.
ってN5
The quoting って: 来ないって, "he says he isn't coming". Before 言ってた or 聞いた, 休みだって is only 休みだ plus this って, not "even".
She said tomorrow is a day off.
らしいN4
Also for friends, but at more of a distance: "apparently". んだって is what someone told you.
Apparently Tanaka is getting married next month.
