[JLPT grammar] Difference between ようだ and かもしれない.

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]

He sings so well that he might become a singer.


ようだ is used to make a conjecture based on information from the five senses and past experiences, suggesting a natural or expected outcome.

かもしれない is used to express the possibility of something happening, even if that possibility is slight.

It is unnatural to use ようだ in this context because the inference that he would naturally become a singer simply because he is a good singer is not warranted. かもしれない is more appropriate here, indicating that it’s possible he could become a singer.


She is beautiful, but she might be married.


She is wearing a wedding ring. It seems she is married.


I hope my explanation helps you. 😊
