[JLPT grammar] The difference between ために and ように

Today I am going to share the homework correction quoted from my JLPT N4 course!
The student’s sentence is not correct. Can you find the mistake?


[Student’s sentence]





[My correction]

I bought glasses so that I could see the letters better.


ために indicates the objective of an action, so a volitional verb should come before ために. However, 見える (to be visible) is not something you do; therefore, you cannot use ために with 見える.
On the other hand, ように expresses the expectation of realizing an objective, so non-volitional verbs like 見える can be used with ように.


I am studying Japanese in order to speak well.

Volitional verb = what you will do.
What you will do is “speak(話す)”, but not “can speak(話せる potential-form)”
So potential-form is not used before ために、but dictionary-form as an action.


I am studying Japanese so that I can speak well.

ように expresses aims by describing ideal situations.
Since it represents a state, “can speak(話せる potential-form)”is used instead of the action “speak (話す)”.


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!
