Questions & Answers about watashi wa ie de shukudai o suru.

What is the role of は in this sentence?

は is the topic marker.

In 私 は 家 で 宿題 を する, 私 is not just the grammatical subject; it is the topic – what the sentence is about.

• 私 = I / me
• は = as for / speaking of

So the nuance is: “As for me, (I) do homework at home.”

Key points:

• は does not always mark the grammatical subject; it marks the topic.
• In many sentences, the topic and subject are the same, which is why it often feels like a subject marker to English speakers.
• In natural Japanese, the topic (私) plus は is often omitted when it’s obvious from context.

Why is は pronounced “wa” here and not “ha”?

When は is used as a particle (like in 私は), it is always pronounced “wa”.

When は is part of a word, it is pronounced “ha”:

• Word: 花 (はな) → hana
• Particle: 私 は → watashi wa

This is an orthographic convention that comes from historical Japanese. Today you just memorize:

• Topic particle は → pronounced “wa”
• As part of a normal word → pronounced “ha”
