Today I am going to share the homework correction quoted from my JLPT N5 course!
The student’s sentence is not correct. Can you find the mistake?

 

[Student’s sentence]

電話番号は書かないでもいいですよ。

*でんわばんごうはかかないでもいいですよ。

[My correction]

電話番号は書かないでもいいですよ。
→電話番号は書かなくてもいいですよ。
You don’t have to write your phone number.

 

◎〜なくてもいい “don’t have to”
×〜ないでもいい

Verb nai-formい+くてもいい
書かな｜い
書かな｜くてもいい

 

e.g.
嫌(きら)いなら、食(た)べなくてもいいですよ。
You don’t have to eat it if you don’t like it.

明日(あした)は会社(かいしゃ)に来(こ)なくてもいいです。
You don’t have to come to the office tomorrow.

 

I hope my explanation helps you. 😊

 

In the JLPT course, all lessons come with homework. If you submit your homework, I will reply with corrections.
I can break down the Japanese grammar and point out mistakes, explaining the structure and nuances of Japanese in an easy-to-understand way.
You can also ask me any questions in as much detail as you want. I will teach you until you get it!
