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]

私のへやはきれくないです。

*わたしのへやはきれくないです。

[My correction]

私のへやはきれくないです。
→私のへやはきれいじゃありません。
My room is not clean.

きれい(綺麗) is a na-adjective, an exception that just happens to end with い.
きれい’s い ending is just part of the word, not the suffix of an i-adjective.

There are other exceptions.

子どものとき、やさいが嫌いでした。
(×子どものとき、やさいが嫌かったです。)
As a child, I hated vegetables.
嫌い（きらい） na-adjective

この歌手はゆうめいじゃありません。
(×この歌手はゆうめくないです。)
This singer is not famous.
有名（ゆうめい）na-adjective

 

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!
