[JLPT grammar] 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]





[My correction]

I’m tired today, so I’ll go to bed early.

「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;

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


I hope my explanation helps you. 😊
