[JLPT grammar] たびに cannot be attached to a word indicating number or amount.

Today I am going to share the homework correction quoted from my JLPT N3 course!
The student’s sentence is not correct. Can you find the mistake?


[Student’s sentence]





[My correction]

The Olympics are held every four years.


ごとに can be attached to a word indicating a number or amount, dividing time or space into units. To express something occurring once every four years, you should use 4年ごとに.

On the other hand, たびに signifies something happening every time a particular event occurs (e.g., オリンピックのたびに = Every time the Olympics are held…). Therefore, using it in your sentence doesn’t convey the correct meaning.


There is a break every hour.

I have to go to the hospital every two months.


I hope my explanation helps you. 😊
