Questions & Answers about ame no hi wa karada ga darukute, nanimo shitakunaikoto ga arimasu.

Why is there a の in 雨の日?

の links two nouns.

• 雨 = rain
• 日 = day

So 雨の日 literally means a rain day, or more naturally, a rainy day / a day when it rains.

This is a very common pattern in Japanese:

• 夏の日 = a summer day
• 休みの日 = a day off
• 日本の映画 = a Japanese movie / a movie from Japan

In this sentence, 雨の日は means as for rainy days or on rainy days.

Why is は attached to 日 in 雨の日は?

The は marks 雨の日 as the topic of the sentence.

So the sentence is structured like:

• 雨の日は = as for rainy days
• 体がだるくて、何もしたくないことがあります = my body feels sluggish, and there are times when I don’t want to do anything

This does not mean rainy days are the grammatical subject in the English sense. It means the speaker is saying, speaking of rainy days...

A very natural English translation is:

• On rainy days, ...
• When it’s rainy, ...

Why is it 体がだるくて and not 体はだるくて?
