Questions & Answers about ame ga yandara, kouen de sanposhimasu.

What does やんだら mean, and what dictionary form does it come from?

やんだら comes from the verb やむ, which means to stop in the sense of rain, snow, wind, noise, pain, and so on coming to an end.

The form is built like this:

• やむ → dictionary form
• やんだ → plain past form
• やんだら → if/when it stops

So 雨がやんだら means if/when the rain stops.

Why is やんだら in a past-looking form if the sentence is about the future?

This is a very common point of confusion.

In Japanese, the conditional 〜たら is made from the past plain form + ら, but that does not mean the whole sentence is talking about the past.

So:

• やんだ by itself = stopped
• やんだら = if/when it stops / after it stops

With 〜たら, the past form is just part of the grammar pattern.

Does 〜たら mean if, when, or after here?
