[JLPT grammar] Which Particle Specifies a Range, に or で?

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]





[My correction]

The highest mountain in Japan is Mt. Fuji.


Particle で can be used to specify a range.
In your sentence,  marks 日本 as the range being discussed.


Only one student in this class speaks French.

English is studied all over the world.

I am the happiest I’ve ever been in my life to be married to her.



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!
