Request lesson : ちゃう & ちゃった = chau & chatta

chau chatta

「もうやんなっちゃう、この暑さ!

= Mou yan nacchau, kono atsusa!

=I am sick of this heat!

Today’s lesson is for my dear twitter follower, Deja!
Actually she gave me many good ideas for the lessons. Thank you, Deja!
If you have a request or a question, follow my Twitter (MaggieSensei) and tweet at me or just leave a message in any comment section here.  I will make a lesson just for you — but only if I think it will help other people. Right now I have tons of requests and ideas lined up so it may take a time, though.

Anyway, let’s get started.

ちゃう&ちゃった ( = chau and chatta)  & じゃう ( = jau) & じゃった  ( = jatta)

ちゃう ( = chau) /じゃう ( = jau) mean “will finish” “will be done” and indicates a complete action.

ちゃった  ( = chatta) /じゃった(=jatta) is a past tense of ちゃう ( = chau) / じゃう  ( = jau)  so it means “to have done”, “to have finished”

These are conversational forms of してしまう ( = shite shimau) and してしまった ( = shite shimatta)

They are very casual and sound a bit childish or sometimes girly and cute. But many adults — even older adults — use them as well.

The original form is

〜(し)てしまう= ~(shi) te shimau

:u:
~(し)ちゃう= (shi) chau
/ ~(ん)じゃう ( = (n) jau)  (conversational)

:u:
past tense

〜(し)てしまった = ~ (shi) te shimatta

:u:

~(し)ちゃった (= (shi) chatta ・〜(ん)じゃった ( = (n) jatta) (conversational)

:mm: How to form  :

First make a past tense and delete ( = ta) ・( = da) and switch with ちゃう ( = chau) / ちゃった ( = chatta)

1) 聞く ( = kiku)  = to hear/listen 

聞い ( = kiita) = heard/ listened / to have heard/listened

聞い ( = kii) + ちゃう ( = chau) / 聞い ( = kii) + ちゃった(=chatta)

:rrrr: 聞いちゃう ( = kiichau) / 聞いちゃった(=kiichatta)

2) 信じる  ( = shinjiru)  = to believe

→ 信じ  ( =  shinjita)   believed/ to have believed

信じ( = shinji) + ちゃう ( = chau) /信じ( = shinji)+ ちゃった ( = chatta)

:rrrr:信じちゃう ( = shinjichau) / 信じちゃった ( = shinnjichatta)

********

3) わかる (= wakaru)  = to understand

わかた  ( = wakatta ) = understood/ to have understood

わかっ ( = waka+ (small tsu) + ちゃう ( = chau)/ わかっ ( = waka + small tsu)+ ちゃった ( = chatta)

:rrrr:わかっちゃう ( = wakacchau) /わかっちゃった ( = wakacchatta)

4) 行く ( =  iku)  = to go 

( =  itta ) = went / to have gone/been

行っ( = i + (small tsu) + ちゃう ( = chau) / 行っ ( = i+small tsu)+ ちゃった ( = chatta)

:rrrr: 行っちゃう ( = icchau) / 行っちゃった ( = icchatta)

*******

5) 飲む = nomu = to drink

= nonda = drank / to have drunken

飲ん ( = non) + じゃう ( = jau) / 飲ん ( = non) +じゃった ( = jatta)

:rrrr:飲んじゃう ( = nonjau) / 飲んじゃった ( = nonjatta)

6) 踏む= fumu = to step on

= funda = stepped on / to have stepped on

踏ん ( = fun) + じゃう ( = jau) / 踏ん ( = fun) +じゃった ( = jatta)

:rrrr:踏んじゃう ( = funjau) / 踏んじゃった  ( = funjatta)

 

:jjj:Basic pattern :

~てしまう( = teshimau) →ちゃう ( = chau)/じゃう ( = jau)

:rrrr: (negative from ) ちゃわない ( = chawanai) / じゃわない ( = jawanai)

~てしまった(=teshimatta) →ちゃった ( = chatta)/ じゃった( = jatta)

:rrrr: (negative from ) ちゃわなかった ( = chawanakatta) / じゃわなかった ( = jawanakatta)

to do する( = suru)

Present tense

(formal)してしまう (= shite shimau)

 (informal) ちゃう ( = shichau )

Past tense

(formal) してしまった ( =  shite  shimatta)

(informal) ちゃった ( = shichatta)

:u:

1) To finish doing something, to complete some action,

to do one’s homework = 宿題をする ( = shujuudai wo suru)

Ex. I will finish my homework by tomorrow.

明日までに宿題をしてしまいます。

=Ashita made ni shukudai wo shite shimaimasu.

:u: (casual)

明日までに宿題をしちゃいます。

= Ashita made ni shukudai wo shichai masu.


:u: (very casual)

明日までに宿題をしちゃおっと。

= Ashita made ni shukudai wo shichaotto!

(talking to yourself)

Have you already finished your homework?

もう宿題をしてしまったのですか?

= Mou shukudai wo shite shimatta no desu ka?

:u: (casual)

Ex.もう宿題をしちゃったの?

= Mou shukudai wo shichatta no?

* to eat = 食べる=taberu


Present tense

(formal) 食べてしまう ( = tabete shimau)

(informal) 食べちゃう ( = tabechau)

Past tense

(formal) 食べてしまった  ( = tabete shimatta)

(informal) 食べちゃった ( = tabechatta)

Can I eat this?

これ食べてもいいですか?

=Kore tabete mo iidesuka?

:u:

Can I finish eating this?

これ食べてしまってもいいですか?

=Kore tabete shimatte mo ii desuka?

:u: (casual)

これ食べてしまっていい?

=Kore tabete shimatte ii?

:u: (more casual)

これ食べちゃっていい?

=Kore tabechatte ii?

What!? Did you eat it already?

えっ!?もう食べてしまったの?

=Eh!? Mou tabete shimattano?

:u: (casual)

えっ!?もう食べちゃったの?

= Eh!? Mou tabechatta no?

:u:  (Negative form )

これ食べちゃわなかったの?

= Kore tabechawanakatta no?

= You didn’t eat this?

:i: Note :

If the stem of the dictionary form ends with ( =bu) , (= mu) , (= nu) or ( = gu)  it becomes じゃう ( = jau ) or じゃった ( = jatta)

 

*〜ぶ ( = 〜bu)
 
 
:rrrr: Ex. 遊ぶ (= asobu )  to play
 
!to right! (informal) 遊んじゃう  ( = asonjau) /(casual past tense) 遊んじゃった ( = asonjatta)

 
*〜む= 〜mu

:rrrr:Ex. 飲む ( = nomu  )= to drink

!to right! (informal) 飲んじゃう ( =  nonjau) /(casual past tense) 飲んじゃった  ( =  nonjatta)

*〜ぬ= 〜nu

:rrrr:Ex. 死ぬ = ( = shinu) = to die

!to right! (informal) 死んじゃう ( =  shinjau) /(casual past tense) 死んじゃった  ( =  shinjatta)

*〜ぐ=〜gu
 
:rrrr: Ex. 騒ぐ  ( =  sawagu )  to go wild, to make noise
 
!to right! (informal) 騒いじゃう( =  sawaijau) /(casual past tense) 騒いじゃった  ( =  sawaijatta)


2) Express your emotion,

* to be in trouble/ to get bothered = 困る ( = komaru)

Ex. 困ってしまいます。

=komatte shimaimasu.

= I will be in trouble.

:u:(casual)

Ex. 困っちゃいます。
=Komacchaimasu.

:u:(more casual)

Ex. 困っちゃう

=Komacchau (sounds girly.)

Ex. そんなことをやってもらったら困ります。

=Sonna koto wo yatte morattara komari masu.

= I will be in trouble if you do such a thing.

(emphasize more/with more emotion)

Ex. そんなことをやってもらったら困ってしまいます。

=Sonna koto wo yatte morattara komatte shimaimasu.

:u: (casual)

Ex. そんなことをやってもらったら困っちゃいます。

=Sonna koto wo yatte morattara komacchai masu.

:u:(more casual)

Ex. そんなことをやってもらったら困っちゃう(sounds girly.)

=Sonna koto wo yatte morattara komacchau.

( :i: For those who have studied How and when to use lesson, you can emphasize more using ( = n)

そんなことをやってもらったら困っちゃうです。

= Sonna koto wo yatte morattara komacchaun desu.

(I will mark other (= n) with yellow today.)

See, you show more emotion with ちゃう ( = chau)

Now compare these sentences,

Did you do this, Maggie?

(1) これマギーがやったの?

= Kore Maggie ga yattano?

(2) これマギーがやっちゃったの?

= Kore Maggie ga yacchatta no?

We use (2) to accuse me more. Like “Why did you do that horrible thing!”

So if someone says to you,

「やっちゃったね。

= Yacchattane.

It often implies a bit of accusation like you did something wrong or made a big mistake.

And now compare these sentences.

When you see your bus is about to leave,

(3) 「バスが行く!」

= Basu ga iku!

(4) 「バスが行っちゃう!」

= Basu ga icchau!

(4) expresses more emotion.

3) To express how shocked or full of regret you are,

Ex.「しまった、家に忘れてきちゃった!」

= Shimatta ie ni wasurete kichatta!

=Oh, shoot! I left it at home.

Ex. なんであんなこと言っちゃっただろう。

= Nande anna koto icchattan darou.

=Why did I say such a thing..

4) To warn,

Ex. そんなに食べると太っちゃうよ!

= Sonnani taberu to futocchauyo!

= Don’t eat so much. You are going to get fat!

5) To suggest something,

Ex. もう、私を置いてっちゃっていいから!

= Mou watashi wo oittechatte iikara!

=Now you can leave without me!

Ex. これ持ってちゃって

= Kore motecchatte!

=Take this with you!

Ex. だまってもらっちゃおうか?

= Damatte moracchaouka?

=You want to just take it without asking? (Literally “Shall we just take it without asking?)


6) To ask for a permission,

Ex. 本当に頂いちゃっていいですか?

= Hontou ni itadaichatte ii desu ka?

=Are you sure it’s OK that I  take this?

Ex. マギー、これ食べちゃっていい?

= Maggie, kore tabechatte ii?

=Maggie, can I eat (all of) this?

(Then I would say 「食べちゃダメ!」( = Tabecha dame! ) = No! You can’t eat it”)

7) To describe what is happening,

ちゃって(い)る ( = chatte (i) ru) 

(formal) てしまっている ( = te shimatte iru)

Ex.ああ、ここが壊れちゃってだ。

= Aa koko ga kowarechatterun da.

=Oh, this is the broken part!

Now you understand more aboutmy previous lesson, イッちゃってる=icchatteru

8) To make you sound cuter or mischievous,

ちゃう ( = chau) and ちゃった ( = chatta) sounds a bit childish and girly so it has the effect of making you sound cuter or mischievous.

Ex.1)「見て!これ買っちゃった

= Mite! Kore kacchatta !

=Look what I bought

Ex.2)「あなたが好きになっちゃった

= Anata ga suki ni nacchatta

= I came to like you.

Ex.3)「言ちゃった

= Icchatta!

=There! I said that!

Ex.4)「バレちゃった?」or 「わかっちゃった?」(When someone got your secret.)

= Barechatta? or Wakacchatta?

=Now you caught me. / Now you know./ Was it obvious?

Ex.5) じゃあ、電話番号、教えちゃおうかな!

= Jaa denwa bangou oshiechaou kana!

=Then should I give you my phone number?

For that reason, if we hear a man keep using these ちゃう(=chau) and ちゃった(=chatta),  we might think he is 

軽い=shallow.

Ex.「あれ、お洒落しちゃって、どうしちゃったわけ?」

= Are? Oshare shichatte dou shichatta wake?

=Wow! You’re all dressed up. What’s the occasion?

Ex. もう、(彼らに)言っちゃってよ、言っちゃって!

= Mou ( karerani) icchatteyo, icchatte!

=Now just tell them, tell them!

From the pic.

もうやんなっちゃう、この暑さ!

= Mou yan nacchau, kono atsusa!

=I am sick of this heat!

•やんなっちゃう( = yannacchau)  : very casual

いやになる (  = iyani naru)

=to get fed up with,  tired of, sick of something, enough for …., drive someone crazy

:u:(casual)

やになる

= Yani naru

:u:(more casual with more emotion.)

やになっちゃう

= Yani nacchau

:u:(more casual)

やんなっちゃう

=Yan nacchau

maggie-sensei マギー先生より= Maggie Sensei yori, From Maggie Sensei

もうそろそろ夏が終わっちゃうはずのにまだまだこの暑さは続いています。

= Mou sorosoro natsu ga owacchau hazu na noni madamada kono atsusa wa tsuzuiteimasu.

= The summer is supposed to be over soon but it is still hot.

もう、体が参っちゃう= Mou karada ga maicchau! =I am wrecked!


!to right!  (If you want to learn another typical casual suffix なきゃ&なくちゃ ( = nakya & nakucha) suffix, go check  this lesson!)

  1. I would like to know how to use “to finish stn” in Japanese

    As I know “to finish stn” can be used by

    Verb-stem + Owaru and Verbてしまうbut I would like to know how to use it correctly and how is it difference ?

    Thank you !!

    1. to finish something (transitive verb) 終える( = oeru ) → 終えてしまう ( = owatte shimau) →chau form: 終えちゃう

      something finishes (intransitive verb) /* sometimes you use it as a transitive verb to finish something (transitive verb)
      → 終わる ( = owaru ) → 終わってしまう ( = owatte shimau) →chau form:終わっちゃう ( = owacchau)

  2. Hi Maggie-Sensei!
    I still can’t grasp the meaning of -te shimau completely because I can’t fully understand the difference of -te shimau when used compared to normal ones. Like for example, if I use -te shimau when asking for permission, what would the difference be when I use -te mo ii?

    Does sentences with -te shimau generally mean they’re negative?

    My native Japanese teacher can’t explain the meaning of te-shimau as well ;-;
    Thanks in advance !!

    1. @エリ

      You mean the difference between てもいい? and しまってもいい? like these?
      1) これ食べてもいいですか?
      2) これ食べてしまってもいいですか?

      1) is simply asking for a permission for an action of eating. “Can I eat this?”. You say that before you eat something. 
      2) is asking for a permission for eating the whole thing. It implies you eat the last piece of something. You say that either before you eat something or when you are already eating. “Can I finish this?”

      So while Vてもいいですか is just asking someone if you can do something or not and you don’t need to fish doing / complete something,
      Vてしまってもいいですか? implies if you can finish doing something.

  3. is this correct?
    “光栄いやっ” is iya~tsu the opposite form of chatta?
    im writing a comic and only know a little japanese ive been using google translate as practice so i dont know if everything is accurate. i want my character to express informally that they are flattered by a compliment.
    Is “光栄いやっ” a correct phrase?

    1. @Haiato

      I wonder how you got いやっ on Google..
      いやっ means “No way!” “Never”(female or children speech for strong negation.)
      So you don’t say 光栄いやっ It just doesn’t make any sense.

      I am flattered in Japanese is
      光栄です。= Kouei desu.
      More casual/male speech a little rough
      それは光栄だ (= Sore wa kouei da)

      Another variation,

      If the character just got some compliment, he/she can also say

      お世辞でもうれしいな (casual)
      (= Oseji demo ureshii na)
      (I know you are trying to be nice but) I am flattered

  4. Hello Maggie-sensei! Although I read most of this lesson, I can’t still get the meaning of this message sent to me. :'(

    “それと、フィリピンといえばバナナをイメージしちゃいますww”

    What does しちゃいます mean in this sentence?

    いろいろとてもありがとうございます

    1. @りつこ

      Hi りつこ
      That しちゃう is used when you can’t control yourself/ you can’t help doing something.

      ~~と言えば〜してしまいます
      →(casual contraction)
      〜と言えば〜しちゃいまいます
      Speaking of ~, I automatically do ~ / I can’t help doing ~

      Speaking of the Philippines, I automatically think of bananas. (I can’t help linking the image to bananas.The first image that I get is bananas.)

  5. I had a lesson with my Japanese teacher from italki on the 22nd of November. Today I had a Japanese friend check my notes to make sure my conjugations were correct and the example sentences I used for the different ways ちゃう/ちゃった were also correct.

    I was wondering if you would be able to confirm some things for me. :3

    ・~でしまいます(じゃう) isn’t really used and can sound awkward and it’s sounds more natural to go with the original ます ending of the verb.

    ・~でしまいます(じゃう) includes a feeling of going against one’s own will.

    1. @184

      Hi 184.
      Well I don’t know what you wrote in your note but
      ・~でしまいます(じゃう) isn’t really used and can sound awkward and it’s sounds more natural to go with the original ます ending of the verb.
      →It depends on the context.
      We do say
      Ex. そんなことをしたら死んでしまいますよ。
      (casual) そんなことをしたら死んじゃうよ。
      when you give an advice.

      ・~でしまいます(じゃう) includes a feeling of going against one’s own will.

      Yes.

  6. I found a few words with しちゃ in front of them.my dictionary says that is a ちゃう variation.but I can’t find an explanation for why it.please help

    1. @Justin
      ちゃ is a casual way to say 〜しては
      Ex. そんなことをしてはいけません。
      = You shouldn’t do such a thing.
      →(casual contraction)
      Ex. そんなことをしちゃいけません。
      = Sonna koto wo shicha ikemasen.

  7. こにちわ 元気ですか

    このページはめっちゃ面白くてすごいですよ。 本当にありがとうございます 

    この文は文法を説明してくるお願いします

    —–>「ちょっとどうしちゃったんだよ二人共」<——-

    本とうにありがとうございます

    1. Hello jehdal
      Sorry for the late answer. I guess me and Maggie haven’t noticed your question, because sometimes there are so many of them…

      Depending on the context ちょっとどうしちゃったんだよ二人共 could mean: “Hey, what’s going on with you, guys!” / “Hey, what’s wrong with you, guys!” / “Hey, what happened, guys!”

      ヨロシク。

      1. @jehdal / 天人

        Thank you 天人さん for answering jehdal’s question.
        Sorry jehdal! I didn’t notice your question until I saw 天人さん’s comment now.
        Good to have have you here, 天人さん!

        1. マギー先生、暖かい言葉ありがとうございます!
          I’m always here for you and for those, who loves to learn Japanese.
          I check your site almost every day, learning something new; people have many questions and their questions (your answers) are a good source of information in order to improve my Japanese.
          Regretfully because of my work I don’t have much time, like before, to learn Japanese. But I try to make up 0,5 – 1 hour/day to spend my free time with my passion.
          居てくれてうれしいです。
          天人より。

          1. @天人

            天人さんありがとう!毎日このサイトに来てくれているんですね。うれしいです。
            これからもよろしくね!
            そして勉強もお仕事もがんばってください!!

  8. ありがとう先生!
    Please explain to me how to use “とんでもない”
    Also, these forms “すごい=すげー/すげぇ”  ”やばい=やべ” Can females use this type of verbs “やべ/すげー” or is it only for males? and please correct my spelling.
    先生、is it possible to add a highlight feature in the comment section? I think it will be more easier to point out something..
    Thanks in advance.

    1. @kuroineko

      Hi kuroineko,
      I don’t think I can add a the highlight feature in the comment section. Sorry.
      You say とんでもない when you deny something strongly.
      Ex. 冬に海で泳ぐなんてとんでもない。
      = There is no way to swim in the ocean in winter.
      Ex. 「お母さん、明日の夜、遊びに行ってもいい?」
      = Mom, can I go out tomorrow night?
      「とんでもないです。」
      = No way.

      Ex. A「Bさんの日本語は上手ですね。」
      = Your Japanese is very good.
      B. 「とんでもないです。」
      = Tondemo nai
      = That’s not true. (being humble)

      “すごい=すげー/すげぇ”  ”やばい=やべ” Can females use this type of verbs “やべ/すげー” or is it only for males?
      It is possible but men use it more. If a girl says すげー/すげぇ/やべー, their parents or adults around them are most likely reprove them.

  9. ありがとう先生!
    As for question 3, I mean in this sentence “みんな 真剣な顔して きばっちゃって” what exactly is “ちゃって” and why is it at the end? Is it a complete sentence?

    I have two questions:

    1. As for “ちゃう” form, can you please tell me which age group can use it?

    2. what is the difference between うるさい and だまれ?Please tell me the exact meaning of “うるさい” does it mean “you’re noisy/annoying/ or shut up? I’m confused >_<

    Thanks in advance.

    1. @kuroineko

      どういたしまして。
      Ah.. OK, we finish a sentence with ちゃって on purpose in the following cases.
      (1) When you point out something.

      どうしたの?真面目な顔しちゃって。= What’s wrong? You look very serious. (By using ちゃって it lightens up the seriousness.)

      (2) When you explain some reason.

      遅れてごめんね。朝寝坊しちゃって。
      I’m sorry I’m late. I overslept so…
      (anastrophe)

      (3) When you describe something.

      彼の部屋はいつも散らかっちゃって…
      = His room is always messy (so you know)…

      Q1) I would say younger people tend to use more than older people. But older people also use it.
      Ex. ご迷惑かけちゃってごめんなさい。= I am sorry that I trouble you.

      Q2) うるさい is just saying “something is too loud” / “annoying” and だまれ is “Shut up!”
      So they are different. If someone listens to the music and it is too loud, you can’t say だまれ because they are not talking. You would say うるさい
      When someone complains a lot or talks back to you, you can say both うるさい・だまれ or even both.

  10. 先生!!はい、私も元気です。
    Thank you so much for answering my questions. You are the best teacher :-D
    However, I know that when talking to yourself, you would use “おう/よう or it depends on the word” at the end. For example, “何をつくろうかな/どうしよう”, but in the case of “宿題をしちゃおっと” is the ending “っと” used to express talking to oneself? and please give me another example for this.

    I have the following questions:
    1. “だまってもらっちゃおうか?” You want to just take it without asking?
    if “黙る” means “to be silent, what exactly is the word for “shut up”? Because usually they would translate this verb as “shut up” I’m confused.

    2. To describe what is happening,ちゃって(い)る form
    Can you please explain it more and give more examples?

    3. How to use “ちゃって” as a connector between sentences. I heard people use it at the end of the sentence and then start a new one ending with “ちゃって” what is this grammar point? is it a connector?

    4. 先生、 you mentioned that when men use “ちゃう” form a lot, they would be called “shallow”. Does that mean that men cannot use them? is it only for females to sound cute?

    5.Please give me another example of “いやになる/やになる”

    1. @kuroineko

      〜っと ending is a very causal way to express your will. It doesn’t matter if other people are listening or not. It is often use when you decide what to do right before you say that.
      何をつくろうかなあ→そうだ、今日は天ぷらをつくろう! I am going to cook Tenpura today.→(casual)今日は天ぷらをつくろっと! Oh maybe I should make a Tenpura today.
      Compare to つくろう、つくろっと gives an impression that you just got the idea what to cook.

      So when you compare 宿題をやろう・やってしまおう:やっちょう (A) and 宿題をやろうっと・やってしまおっと・(やっちゃおっと)(B), while A shows your will that you are going to do homework in general, you use B, when you were doing/talking about something else and you just remembered you have to do your homework. Oh, I guess I have to finish my homework.

      1. Ah… OK, though だまってもらっちゃおうか?” is VERY casual,
      “V+てもらおうか/V+てもらいましょうか/V+てもらっちゃおう” are sort of command form.
      Do something

      It shows the listener owes the speaker to do something. It may sound polite but it sounds very demanding.
      だまってもらおうか・だまってもらいましょうか・だまってもらっちゃおうか= I want you to shut up = So it means “Shut up!”

      2. For example

      Ex. 答えがみえちゃっているんですけど。
      = Kotae ga miechatte irunndesukedo.
      = I can see the answer. (You are showing the answer)

      Ex. ストレスがたまっちゃって…
      =Sutoresu ga tamachatte.
      = I am stressed up.

      3. I don’t understand your question well.
      You mean finish a sentence with ちゃった and then continue with ちゃって?

      I can’t think of any example.. Sorry.

      4. No. men can use it but overusing ちゃう sounds shallow. That’s all.

      5. OK,
      Ex. 毎日雨ばっかりでいやになっちゃう。
      Ex. 勉強、勉強でいやになっちゃう。

      Hope I answered your questions (except 3)

  11. 先生!!おひさしぶりです!!元気でしたか? :-D :-D
    I hope you are fine and everything is well. Thank you always for supporting us and helping us to learn this wonderful language.

    I have the following questions:

    1. 明日までに宿題をしちゃおっと。You said (when talking to yourself), can you please explain this form? (ちゃおっと)?

    2. In this sentence”Did you have dinner already?”
    How to use “ちゃう” form here?

    3. “そんなことをやってもらったら困ります。” what is the meaning of “やってもらったら” here?

    4. “忘れてきちゃった” what is “きちゃった”?

    Thanks in advance. !JYANE!

      わ〜久しぶりですね!はい、元気ですよ。kuroinekoさんも元気でしたか?
      OK, let me see your questions…

      1. 宿題をしちゃう is a casual form of 宿題をしてしまう(to finish doing my homework/to have my homework done)
      This is a very casual speech but when you talk to yourself showing your will, you say
      宿題をしてしまおっと = I guess I will finish my homework.
      And the casual contraction of してしまう is しちゃう so you can also say
      宿題をしちゃおっと

      I will show you other examples. りですね!はい、元気ですよ。kuroinekoさんも元気でしたか?
      OK, let me see your questions…

      1. 宿題をしちゃう is a casual form of 宿題をしてしまう(to finish doing my homework/to have my homework done)

      This is a very casual speech but when you talk to yourself showing your will, you say

      宿題をしようかな = I guess I am going to do my homework.

      Use 〜(し)てしまう(to have done something / to finish doing something) form.

      宿題をしてしまおうかな = I guess I will have my homework done.

      You can also say
      宿題をしてしまおっと = I guess I will finish my homework.
      And the casual contraction of してしまう is しちゃう so you can also say
      宿題をしちゃおっと

      You may not learn this in your textbook but we say this often in casual conversation.

      Ex. I guess I will go to sleep now.

      もう寝ようかな

      Use 〜(し)てしまう(to have done something / to finish doing something) form.
      もう寝てしまおうかな

      もう寝ちゃおうかな。
      ↓ Showing your stronger will in a casual way
      もう寝ちゃおっと

      Ex. I guess I am going to eat this.

      これ食べようかな

      Use 〜(し)てしまう( to finish eating)
      これ食べてしまおうかな。

      これ食べちゃおうかな。
      ↓ Showing your stronger will in a casual way
      これ食べちゃおっと 

      2) Did you have dinner already →もう夕食食べちゃった?

      3) We usually use V+てもらう when you receive some favorable action from others.
      But we sometimes use V+てもらう for negative situations.
      In this case, やってもらったら困る is sarcasm. You insinuate the feeling of “I will be in trouble if you are free to do such a thing.”

      Other examples
      Ex, そんなところに書いてもらったら困ります。
      You shouldn’t write it in such a place. (I will be in trouble.)

      4) 忘れてきちゃった is a casual contraction of 忘れてきてしまった= to have left something you need somewhere

      OK, I guess that’s all.
      Hope I answered your questions.

      おやすみなさい zzz

  12. Great lesson! I do have one question, and I apologize in advance if it was discussed in the article. Can you make chatta or chau negative, and if so how do you form it? Thanks in advance!

    1. Hello Alaina,
      Apology accepted.

      Present negative:
      ~てしまう=>~てしまわない=>食べてしまわない
      ~ちゃう=>~ちゃわない =>食べちゃわない/食べちゃわん (~ちゃわん more casual)

      Past negative:
      ~てしまった=>~てしまわなかった=>食べてしまわなかった
      ~ちゃった=>~ちゃわなかった=>食べちゃわなかった

      To fully understand ~てしまう I advise you to read the whole lesson.

      ご参考になれば。

  13. こにちは先生!

    “本当の夫婦になっちゃおうか?”

    Does that translate into “Shall we become officially married couple ?”

  14. こんばんは!
    また質問があります。

    1.A: やちゃったね
      B:えぇぇ、わたしじゃない/ わたしではありません

    Are there any difference between じゃない and ではありません in terms of meaning and usage? If there is, how do we use them, say, for the above example?

    2.How should we address someone? For example, 渡辺リオ. Do we address her as 渡辺さん or リオさん if we first met each other?

    あけましておめでとう!

    1. @Aki

      Happy New Year! Aki!
      1) じゃない is much more casual than ではない
      I have a lesson on that theme. Please check じゃない&んじゃない

      2) It depends on the person but generally speaking if you see someone for the first time, it will be safe to address them with family name with さん 渡辺さん
      But if that person introduce themselves with their first name, you can call that person first name with さん リオさん

  15. Is there any particular way of knowing the formation of different verb using chau~? For example; wakacchatta, barechatta,icchatta, kacchata ( Some with one ‘c’ and some with 2’c’) Confusing~~~

      1. Thank you so much for your consideration. :) It is the part when you add the small tsu that confuses me. I am having problem as to which verb to add small tsu or vice versa. :(

        1. @anna

          OK, if you have a problem with って then you might want to review how to make て-form as well. You can always check the verb lists but there is a way to remember the basic ones with a song.
          Go google the te-song. You will figure out when you use っ, ん,い and exception in a fun way.
          Here is the lyrics. It will be easier to remember with songs. There are a lot of videos on Youtube.

          ★masu form

          い・ち・り 「って」
          び・み・に 「んで」
          き 「いて」  ぎ 「いで」
          し 「して」
          例外 行きます 「行って」

          Ex. 買います= かいます
          The letter before ます is い so it will use って
          買って
          past tense : 買った

          ★dictionary form :

          う・つ・る 「って」
          ぶ・む・ぬ 「んで」
          く 「いて」  ぐ 「いで」
          す 「する」
          例外 行く 「行って」

          Ex. 散る = ちる = the last letter is る so you use って
          →散って
          past tense 散った= ちった

          Ex. 読む= よむ= the last letter is む so you use んで
          →読んで
          past tense : 読んだ

  16. Can you tell me what kind of construction is -てもらっちゃ and it’s translation?
    The sentence is 忘れてもらっちゃ 困るよ! The context is a bullied person that forgot her past and meets with the man that bullied her. He attacks her and when she remembered him this was what he replied, the next sentence is that her father arruined his life.
    girl: 久保山君…
    man: お~ そうだよ
    man: 忘れてもらっちゃ 困るよ!
    man: 俺の人生 お前の親父が 全部 狂わせたんだ!

    I would like to know if the full sentence is 忘れてもらては or if it’s a construction with しまう or if it’s another shortening.
    Thank you in advance and sorry if here is not the place to ask about it. BTW, do you have now a Maggie room?

    1. @Ana

      Hello Ana! Sorry, currently Maggie’s Room is down but will put it back eventually. Meanwhile, feel free to leave a comment or question any comment section or contact me on Facebook or Twitter.
      忘れてもらっちゃ困る is a casual contraction and it is from
      忘れてもらっては困る

      Usually もらう is “to have someone to do something for you” so you could just say
      忘れたら困る
      or
      忘れては困る
      But when we use the verb like 困る, we use もらっては to add a feeling of sarcasm and emphasize what action cause the problem.
      So the translation is just
      “If you forget about it, I will be in trouble” → Don’t forget about it!

      *(unfavorable action) (し)てもらっては困る→〜もらっちゃ困る
      Ex. こんなところに荷物を置いてもらっちゃ困る。
      = Konna tokoro ni nimotsu wo oite moraccha komaru.
      = Don’t leave your bags (personal belongings) here.(I will be in trouble.)

      Ex. 好きな様にやってもらっても困ります。
      = Sukina you ni yatte moratte mo komarimasu.
      = You can’t just do anything you want. (I will be in trouble.)

  17. Hello Maggie先生,
    I’m confused by two example sentences; is
    「これ持ってちゃって」 short for
    「これ持っていてしまって」 ? If so, is there a difference to
    「これ持っちゃって」 ?

    Does the small っ in 「もう、私を置いてっちゃっていいから!」 come from いく, or is it a mistake?
    Thank you for your time, I really like the site!

    1. @negi
      Hi negi!! OK,
      1) これ持ってっちゃって came from これ(を)持っていってしまって(ください)

      Your sentence これ持っちゃって is from これ(を)持ってしまって(ください)and it means “to hold something”

      2) 「もう、私を置いてっちゃっていいから!」
      It is a very casual contraction and we sometimes skip い
      もう置いていっちゃっていいから→もう置いてっちゃっていいから

      1. So the verbs were 持っていく and 置いていく.
        Then shouldn’t it be 「これ持ってっちゃって!」?
        As the difference is very subtle when spoken, can one assume that …て(っ)ちゃって is usually from …いく+しまって, in other words, is …ている+しまって ever used?

        1. @negi

          Sorry, there was a typo. You are right. 持ってっちゃって

          *持っていって(しまって)→持っていっちゃって→持ってっちゃって = Take it with you
          *持って(しまって)→持っちゃって = Hold it

          *置いていって(しまって)→置いていっちゃって→置いてっちゃって = Leave it here
          *置いて(しまって)→置いちゃって = Put it here.

          As for your question,
          If the form ~ いる+しまう ever used…
          You can express what is happening now with ~てしまっている (~ちゃっている)instead of いる+しまう

  18. Hello, sensei!
    I have a doubt with the meaning of 「そんなことをやってもらったら困ります」. Does it mean “You’ll get in trouble if you do something like that (for me)”?

    Thank you very much for this lesson, Sensei!

    PS: There’s a little mistake in
    「Ex. そんなことをやってもらったら困ってしまいます。
    =Sonna koto wo yatte morattara komari masu.」
    ^^

    1. @Orti

      Hi Orti! Thank you for spotting the mistake and sorry I didn’t put the translation there.
      「そんなことをやってもらったら困ります」means
      I will be in trouble if you do that.

      1. どういたしましてと同時に有り難うございます ^^
        would it be a different structure if you wanted to say “you will be in trouble if you do that”? or is it “I will be in trouble…..” just because the subject isn’t mentioned?

        1. @Orti

          I know Japanese is sometimes confusing because we often skip the subject and unlike Spanish, we can’t always tell the subject by the conjugation of the verbs.
          But in this case, やってもらう is a key word here. Someone does something for/to me.
          And it is not natural to use 困っちゃう if the subject is you unless you add でしょ (aren’t you, won’t you) etc.
          You will be in trouble if I do that, won’t you?
          私がそんなことしたら困っちゃうでしょ。(casual)
          I will be in trouble if you (or someone) do(does) that.
          そんなことをされたら/してもらったら/やってもらったら/されたら/困っちゃう
          そんなことやってもらったら困っちゃう。

          1. aah, I see, it’s more complicated than what I tought, but I hope it’s just a matter of practice :P

            有り難う、先生!

  19. マギー先生、こんにちは!

    first of all, i love your page, i always read it, and it helps me a LOT! thanks ^^

    but i have a quick question about しちゃう.(maybe its a bit silly question ><") at the part "express your emotions", do you use it just with bad things?? like you wrote, when you miss the bus, or you are in trouble, or did something wrong. is it emphasize the emotions just about bad things?

    1. @sacchan

      こんにちは!Sacchan! !happyface!
      Thank you for your nice comment! I am glad to hear my site helps you.
      Oh, it is a good question. No, しちゃう can be used for neutral or positive things as well.
      I separated “expressing one’s emotions” and “To finish doing something, to complete some action” but you can express your emotion when someone complete an action.
      For example

      もう宿題終わっちゃったの? You are impressed that someone has finished the homework.
      これもらっちゃった!= I got this from (someone) (You are happy or bragging.)
      試験に受かっちゃった!= I got to pass the exam! (Happy feelings.)

  20. Thanks so much for this lesson. My Japanese grammar book teaches all kinds of lofty ideas about elevated usage and so on, but doesn’t really go into this kind of colloquial Japanese. It’s nice to be able to watch anime, drama and so on and think ‘ah, I just learned that!’.

    1. @TolpuddleMartyr

      こちらこそ!Thank you for your comment!
      What you learn from grammar books and teachers are essential. But if you don’t know colloquial Japanese, you won’t be able to understand the real conversation because we don’t always talk like a text book.
      また来てね!

  21. Hi Maggie-sensei ^^
    I just have a question about the conjugation of ちゃう/ちゃった。

    I have been told that for verbs like 飲む、読む、遊ぶ etc, when using the casual version of ~てしまいました/しまった they turn into ~じゃった. Is this correct?
    e.g.

    全部飲んでいた → 全部読んでしまった → 全部飲んじゃった
    “I drank everything!! >..<

    1. @hanoi_j

      Yes, since I wanted to concentrate just ちゃう and ちゃった, I didn’t write about じゃった but maybe I should add the information.
      Your sentence is correct
      全部飲んじゃった = I drank everything

      1. Oops, for some reason my question didn’t fully send, sorry >.<

        I did go on to ask, if it's じゃった for the past-form, then does that mean it is じゃう for the present form?

        e.g. 明日に読んでしまいます → 明日に読んじゃう!
        I'll finish reading it by tomorrow!

        Thank you ^^

        1. @hanoi_j

          I just added the information of じゃう/じゃった
          明日に読んでしまいます → 明日に読んじゃう!
          じゃうpart is correct. And yes, you can use it for the future.
          Just 明日”に” is strange. Either 明日(without particle) or 明日までに is better.
          明日までに読んでしまいます。→ 明日までに読んじゃう!

  22. Howdy! Love the site! I have a quick question!
    Can you use ちゃう in the emotional sense to express regret for things that are uncontrollable?
    For example: 寒くなっちゃった!

    Cheers!

    1. @Foolofatook

      Hi!! はじめまして!(かな?)
      All very conversational but for example,
      “また(=again)寒くなっちゃったね!”
      “突然(とつぜん= suddenly)寒くなっちゃった”
      etc.

  23. Hi Maggie-sensei, I have a question. Are these valid Japanese expressions?
    もうラブラブになっちゃって
    横隔膜突っ張っちゃって
    強烈な味にぶっ飛んで
    等身大の裏表
    脅迫的に縛っちゃって
    網膜の上に貼っちゃって
    もうラブラブでいっちゃってよ
    会いたいたいない、無い!

    1. @twofaced-error

      It must be some lyrics. 初音ミク? 
      もうラブラブになっちゃって、means They got lovey dovey.
      強烈な味にぶっ飛んで : ぶっ飛ぶ means “to get really surprised with the strong taste (It is a very extreme expression.)
      But other words are just play of words so I don’t know if you can learn Japanese from it. But you can see lots of ちゃって from it huh?

      1. Haha, Maggie-sensei, you got it right. It’s the chorus from Ura-Omote Errors. I was trying to clear things up for myself because of all the different contradicting translations and explanations of the lyrics. I always wondered why the composer wrote a lot of ちゃって in there. At least “toushindai no ura-omote” was the only thing I could understand.

  24. Sensei!
    This is quite sometime already but I want to ask this:

    ちゃうやちゃったは「しまう、しまった」
    Its short for しまいます&しまいました
    But aren’t they use for time when its like you did something and regret something. Or something like It’s not exactly good thing to do. Isn’t it?

    1. @Sakuraiba201

      Yes, it is. As I wrote in the lesson, “ちゃった” expresses the feeling of regret for the things you have done.
      Please read the part in the lesson,

      To express how shocked or full of regret you are,
      Ex.「しまった、家に忘れてきちゃった!」~~~

    1. @Gabriel

      こちらこそ、コメントありがとう!よかったら「〜ちゃ&〜きゃ」の使い方、練習(れんしゅう)してみてね。

  25. Sorry, I have two questions.

    1) I saw a foreigner on a Japanese show answering a question from a Japanese panellist who told him “So do you think the Japanese are a little picky?”:

    言っちゃえば、そうですね。

    That means something like: “Well, if I might say so…”. What kind of use is that one?

    2) Are 言っちゃった and ばれちゃった always girly? Oooooops, I kind of used them often.

    1. @Cygnus Nazca
      Sorry that it took me a long time to answer your question. Now I am back and able to answer your question with time.
      1) 言っちゃえば、そうですね。 Maybe he meant to say→ まあ、そう言っちゃえば、そうですね。It means “I would say yes.””Yo diría que sí ” or he might have tried to translate ”to tell you the truth” in casual Japanese. and he meant to say ぶっちゃけそうですね (very casual) 

      2) Men can say 言っちゃった、ばれちゃった. If you are young, it is totally acceptable. But I would say don’t over use it. Check my reply to @Vanli

  26. So guys shouldn’t use ちゃう Or ちゃった Tto much because it will make them seem shallow? So then do they use てしまう And てしまった Instead? Or juts try not to use the whole expression all together too much?

    Thank you

    1. @Vanli
      Don’t worry too much. Many guys use it and it is natural. But don’t overused it. チャラ男 = charao (slang for a shallow guy) has image to use this too much so..
      It also depends on how you deliver it,too.

    1. @Top

      You mean バレバレ!? Then it means “too obvious”
      ばれる= bareru =some secret is out,
      ばれたか! = Now you know (the secret). You caught me.
      バレバレのうそ= Obvious lie

  27. Oh…very clear now^^Thank you much, sensei^^
    I’ve seen it before in Manga…no wonder I have trouble understanding Manga.

  28. Oh yesss…I’ll put that on my twitter^^ lol
    Thank you much^^
    Oh…and one more question, please?
    Your example …しちゃおっと。 Why is it おっと?

    1. @Top
      Good question!!!
      ~(し)ちゃおっと! is another casual expression to show your intention to finish doing something.

      First, have you ever heard these expressions?

      Ex. 食べる→食べよっと I am gonna eat!
      Ex. 寝る→寝よっと I am gonna sleep!
      Ex. 勉強する→勉強しよっと! I am gonna study!
      We say this when we talk to ourselves (in front of others)

      When you imply finishing the action, you say ちゃおっと = I’m going to have finished + verb

      →これ食べちゃおっと! I am going to finish eating this.
      →もう寝ちゃおっと! I am going to sleep now.
      →勉強しちゃおっと! I am going to have finished studying!

      It requires your will to do something or finish something so your previous phrase 疲れちゃう won’t work here.
      X 疲れちゃおっと I am willing to get tired.
