[JLPT grammar] 〜かどうか is not used with a question word.

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 don’t know how spicy that dish is.


〜かどうか is not used with [question word+か].
Your sentence has どのくらい(question word), so 〜かどうか is not used.

(no question word)

(question word=どのくらい)

(question word=どのくらい)


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!
