Questions & Answers about toshokan wa kuji ni shimarimasu.

Why is は pronounced wa here instead of ha?

When は is used as the topic particle, it is pronounced wa, not ha.

So in this sentence:

• 図書館は = toshokan wa

This is a special rule for the particle は.
If は appears as part of a normal word, it is usually pronounced ha.

What does the particle は mean in this sentence?

は marks the topic of the sentence: what the sentence is about.

So 図書館は means something like:

• As for the library...
• The library...

In natural English, we often just translate it as the library, but the Japanese nuance is more like introducing the topic.

What does に do after 九時?
