[Common Mistakes] How to make the contraction style of てしまう

Today I am going to share the homework correction quoted from my JLPT N3 course!
The student’s sentence is not correct. Can you find the mistake?

 

[Student’s sentence]

今日はつかれたから、早く寝っちゃいたい。

*きょうはつかれたから、はやくねっちゃいたい。

 



 

[My correction]

今日はつかれたから、早く寝っちゃいたい。
→今日はつかれたから、早く寝ちゃいたい。
I’m tired today, so I’ll go to bed early.

JP;
「寝ちゃいたい」は「寝てしまいたい(want to fall asleep)」の縮約形(しゅくやくけい contraction)です。

寝てしまいたい→寝るte-form+〜てしまう+〜たい

まず、「寝る」のte-formは「寝て」です。「寝って」じゃありません。

「〜てしまう」の縮約形の作(つく)り方(かた)
te-formてしまう→〜ちゃう
てしまう→寝ちゃう

「〜たい」をつけると、te-formてしまう+たい=te-formてしまいたい
縮約形は、〜ちゃう+たい=〜ちゃいたい
てしまいたい→寝ちゃいたい

EN;
寝ちゃいたい is the contraction style of 寝てしまいたい(want to fall asleep).

寝てしまいたい→寝るte-form+〜てしまう(to do something by accident)+〜たい(want)

First, the te-form of 寝る is 寝て, not 寝って.

How to make a contraction style of 〜てしまう;
te-formてしまう→〜ちゃう
てしまう→寝ちゃう

When たい is added, te-formてしまう+たい=te-formてしまいたい
The contraction style is〜ちゃう+たい=〜ちゃいたい
てしまいたい→寝ちゃいたい

 

I hope my explanation helps you. 😊
