Hi Makoto and Momoko here.

It’s about time to make a lesson together. 

Today we am going to make a lesson on だって ( = datte).

You may hear this a lot in conversation. 


Today I am going to make a lesson on だって ( = datte).

You may hear this a lot in conversation. 

1) to quote what someone says: When you quote what you have heard* When you quote what you have heard

★ How to form: 

*noun / na-adjective + だって ( = datte)

→(Note: verb / i-adjective + って ( = tte) / verb んだって ( = n datte) )


Ex. パパがマギー先生はきれいだって言ってたよ。

= Papa ga Maggie Sensei wa kirei datte itteta yo.

= My dad says Maggie Sensei is beautiful.

Ex. 明日は雨だって

= Ashita wa ame datte.

= I heard it is going to rain tomorrow.

Note: I already explain in my Indirect and Direct speech &  って ( = tte) lesson so please check this lesson for all the details. 

2)  to give a reason / to make an excuse/ to talk back: because: 

You start your sentence with だって ( = datte) to explain why. 

You use it in very casual conversation when you talk to someone very close to you.

Ex. 「よく食べるね。」

= Yoku taberu ne.

= You eat a lot, don’t you?


= Datte, onaka suite irun damon.

= ‘Cause I am hungry.

Note: もん ( = mon) is a casual contraction of もの ( = damono) 

In this case it means “から ( = kara)” 

You often it use with だって ( = datte) in casual speech. 

Children tend to use だって ( = datte) to make excuses.

Ex. Mother:「 どうしてサキちゃんにそんなことしたの?」

= Doushite Saki-chan ni sonna koto shita no?

= Why did you do such a thing to Saki-chan?

Child だって、おもちゃを貸してくれないんだもん。」

=  Enough with your excuses.

= Give me some nuts! 


= Sakki tabeta bakari janai.

  1. Thanks for the great lesson! Just a question: I was doing some more reading regarding だって 、and I saw a very similar grammar point 、「たって」。It seems that these mesanings are the same, and maybe even when だって is in the middle of a sentence it is the exact same as when you use たって with a noun (it becomes だって)。Are these two grammar points the exact same or is there a bit of a difference? Thank you so much!

    1. Hi Rebekah,

      Actually there are a couple of usages of たって but you are probably talking about
      verb past tense + って. or i-adjective く + たって
      If so, you are right. It is the same as だって and it means Vても (even doing something)

      Ex. どれだけ食べたって太らない = どれだけ食べても太らない = No matter how much one eats, one doesn’t get fat.
      Ex. 今は、彼女に何を言ったって無駄だ。 = 今は、彼女に何をいっても無駄だ。= It’s no use telling her anything now.
      Ex. どんなに美味しくたって高ければいらない。 = どんなに美味しくても高ければいらない。 = No matter how delicious it is, if it is expensive, I am not going to buy.

  2. Hi sensei, what does “datte” mean here? emphasis?


    thank you :3

    1. Hi Megu,
      It is a conversational expression but let me explain.
      If this person is talking to her senpai (senpai is one’s senior who entered the school/company earlier than the speaker)
      I decided that you are special.(It may sound too dramatic but she is saying “I hereby declare that I like you!” )

  3. ということは、「だって」というのは「でも」のカジュアルの言い方ですか?

    1. 「小学生だって/でもこの問題を解けるよ」

  4. Hi Maggie,

    Shouldn’t this sentence use instead 教えてあげます of 教えてくれます?
    I thought if you are speaking, and you give something to someone (or do something for someone), you always use あげます because くれます is reserved for when you are the receiver.

    1. Hi Dennis,

      Good question. It is because I am not neither a hamster nor turtle. I am talking about they give the readers lessons.
      If I am talking about myself, it sounds a bit arrogant but I could say 日本語を教えてあげます。

      1. I see, thank you. So as a third party, it is okay to say くれます. Are both くれます and あげます fine to use when you are a third party?

        1. You can use くれる if the receiver is the one you are talking to.

          Someone (the third person) が (listener/readerに) Vてくれるよ・くれますよ
          = “Someone does something for you*” (you = the listener/reader) *or someone who you can related to.

          As for あげる, the speaker has to be yourself.
          Aがみんなに日本語を教えてあげる (Not natural)
