Questions & Answers about byouin wa kare no shibou o kakuninshimashita.

What is the basic grammar pattern of this sentence?

The sentence follows this pattern:

病院 は / 彼 の 死亡 を / 確認しました

So the structure is:

• 病院は = as for the hospital / the hospital
• 彼の死亡を = his death
• 確認しました = confirmed

A natural breakdown is:

• Topic: 病院は
• Object: 彼の死亡を
• Verb: 確認しました

Japanese often puts the verb at the end, so the sentence literally feels like:

As for the hospital, his death confirmed.

In natural English, that becomes:

The hospital confirmed his death.

Why is は used after 病院 instead of が?

は marks the topic of the sentence, while が more strongly marks the grammatical subject or introduces new information.

So:

• 病院は彼の死亡を確認しました。
  = As for the hospital, it confirmed his death.

This sounds neutral and natural if the hospital is already the thing being talked about, or if the speaker is simply presenting it as the topic.

If you used が:

• 病院が彼の死亡を確認しました。

that would put more focus on the hospital as the one that did the confirming, perhaps contrasting it with someone else.

In many contexts, both are possible, but は often sounds smoother in plain narration.
