[JLPT grammar] Don’t use 〜ぱなし verbs represents a change

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


[Student’s sentence]





[My correction]

→ お菓子を食べすぎて、太ってしまいました
I ate too many sweets and gained weight.


The expression 〜ぱなし (leave on, leave out, leave as is) indicates that a situation continues; however, 太る (to gain weight) represents a change in weight gain, not a continuous state. Therefore, it is not appropriate to use 〜ぱなし with the verb 太る.

Here are some example sentences where 〜ぱなし can be used.


I left the window open and went out.

I was tired from driving for 6 hours straight yesterday.

Tanaka-san’s talk was so interesting that we couldn’t stop laughing.


I hope my explanation helps you. 😊
