Questions & Answers about doushite kyou wa sonnani isoide iru ndesu ka?

Why is 今日 followed by は here?

は marks 今日 as the topic: as for today.

So the sentence has a nuance like why are you in such a hurry today, specifically? It can sound as if today is a little unusual compared with other days.

A time word like 今日 can sometimes appear without a particle, so どうして今日そんなに急いでいるんですか is also possible. Using は just gives 今日 a bit more focus or contrast.

What does どうして mean here, and how is it different from なぜ or なんで?

どうして is a common way to say why? or how come?

Compared with similar words:

• どうして: neutral and common in conversation
• なんで: more casual
• なぜ: more formal, more written, or more serious-sounding

So どうして fits very naturally in a polite spoken question like this.

What does そんなに add to the sentence?

そんなに means that much, so much, or to that extent.

Here it modifies 急いでいる, so it means something like:

• being in such a hurry
