覚え方のコツ Memory Tip
医療文脈で『傷や血流障害の先に起こる、組織が死んで黒ずみ、腐敗まで進む危険な状態』として場面ごと覚えると残りやすい語です。単なる injury や wound ではなく、tissue death が広がる深刻さが核。necrosis が壊死一般なら、gangrene は手足などで感染・腐敗を伴い、amputation の判断にもつながりやすい重い語。形容詞は gangrenous。
Remember `gangrene` as a serious medical word, not just a simple wound word. It often appears in contexts about damaged tissue, infection, and sometimes even amputation. Linking it with words like `gangrenous`, `tissue death`, and hospital situations will help it stay in memory.

gangrene の語源・成り立ち Etymology
ラテン語 gangraena を経て、ギリシャ語 gangraina「腐って広がる傷」にさかのぼります。病変が周囲を“食うように”進む感覚が、壊疽という意味につながりました。関連語に gangrenous があります。
Gangrene comes through Latin gangraena from Greek gangraina, meaning a spreading sore or rotting wound. The original image was of decay that seems to eat into the surrounding flesh. From that, the word developed into the medical term for tissue death and spreading corruption. A related word is gangrenous.
