Questions & Answers about shoubyousha wa kossetsu kamo shirenai.

What does 傷病者 mean exactly?

傷病者（しょうびょうしゃ） is a formal term used in medical, emergency, rescue, or disaster contexts.

• 傷 = injury
• 病 = illness
• 者 = person

So it means something like an injured or ill person, a casualty, or a patient/victim depending on context.

It is more technical than everyday words like:

• けが人 = injured person
• 患者 = patient

So this sentence sounds more like an emergency assessment than casual conversation.

Why is は used after 傷病者?

は marks the topic of the sentence.

So 傷病者は means as for the casualty / regarding the injured person.

It does not mean is by itself.
Instead, it tells you what the sentence is about, and the rest of the sentence gives information about that topic.

So the structure is roughly:

• 傷病者は = as for the casualty
• 骨折かもしれない = might have a fracture / might be fractured

What is 骨折 here? Is it a noun or a verb?
