Today, I am going to share the homework correction from my JLPT N5 course!
The student’s sentence is not correct. Can you find the mistake?

 

[Student’s sentence]

このレストランはおいしいと安いです。

*このれすとらんはおいしいとやすいです。

[My correction]

このレストランはおいしいと安いです。
→このレストランはおいしくて安いです。

This restaurant is delicious and inexpensive.

 

When you put two words together, if the word you want to connect is a noun, you can use の. But since おいしい is an i-adjective, you cannot use の.
When you connect i-adjectives, you have to use the te-form, so おいしい becomes おいしくて.

How to make the te-form of an i-adjective;
i-adjective (remove い) ＋ くて
おいし｜い dictionary form
おいし｜くて te-form

 

e.g.
母(はは)はやさしくて、明(あか)るいです。
My mother is kind and cheerful.

 

東京(とうきょう)は人(ひと)が多(おお)くて、にぎやかです。
Tokyo is crowded and lively.

 

兄(あに)は背(せ)が高(たか)くて、声(こえ)も大(おお)きいです。
My elder brother is tall and has a loud voice.

 

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!
