ごとに

ごとに is a Japanese grammatical expression used to indicate repetition or occurrence at regular intervals or in relation to specific categories.

When used after a noun or verb, it suggests that something occurs each time that noun or verb is referenced. It is similar to saying 'every' or 'each' in English. For example, you can use it to describe how often an event occurs or how frequently you do something.

• After a noun: 月[つき]ごとに (every month)
• After a verb: 行く[いく]ごとに (each time [I] go)

This expression is versatile and can be used in various contexts, making it a helpful structure for learners to express repetitive actions clearly.
