Today I am going to share the homework correction quoted from my JLPT N4 course!
The student’s sentence is not correct. Can you find the mistake?

 

[Student’s sentence]

A：ランチに何(なに)を食(た)べましょうか。
B：何もいいですよ。

[My correction]

何もいいですよ。
→何でもいいですよ。
Anything is fine.

 

何も means “nothing”, and it is used in negative sentences(何も〜ない).
何でも means “anything”, and it is used in affirmative sentences.
Since you said いいです—which means ‘okay’ or ‘fine,’ and it is affirmative—you should use 何でも, not 何も.

 

e.g.
れいぞうこに何もありません。(a negative sentence)
There is nothing in the refrigerator.

むすめには何でも買(か)ってあげたい。(an affirmative sentence)
I would buy anything for my daughter.

私(わたし)は何もしていません。(a negative sentence)
I have done nothing.

何でもいいので、知(し)っていることを話(はな)してください。(an affirmative sentence)
Tell us what you know, whatever it is.

 

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 as much as you want. I will teach you until you get it!
