[JLPT grammar] Which Should We Use: は or が for Noun Modification

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

 

[Student’s sentence]

これは私は日本で買ったかばんです。

*これはわたしはにほんでかったかばんです。



[My correction]

これは私は日本で買ったかばんです。
→これは私が日本で買ったかばんです。
This is a bag I bought in Japan.

 

When a clause with “は” modifies a noun, you should replace “は” with “が”. This is because “が” highlights the subject in a sentence that describes a noun.

これはかばんです。(This is a bag)+私は日本で買いました。(I bought in Japan)
=これは「私日本で買いました」かばんです。
=これは「私日本で買った」かばんです。

*When modifying a noun in Japanese, the verb before the noun should be in its plain style (買った), not the polite style (買いました).

 

e.g.
◎これは母作(つく)ったケーキです。
(×これは母作ったケーキです。)
This is a cake my mother made.

◎私友だちと先週(せんしゅう)見(み)た映画(えいが)はおもしろかったです。
(×私友だちと先週見た映画はおもしろかったです。)
The movie I saw last week with my friend was interesting.

 

I hope my explanation helps you.😊
