记音：gangrene≈'干根'，血供中断的组织像干枯的根一样坏死腐烂。
语域：formal 常见场景：medical reports、clinical notes、patient education materials 该词为医学术语，多用于正式或专业语境，如病历、医学教材或医患沟通中；日常口语中较少使用。
按给定读音 /ˈɡænɡrin/，gangrene 的重音在第一音节，首音节为 /ɡæn/，不是拼写暗示的 /ɡæŋ/。gangster、ganglion 因此只是形近词，读音不同，不押韵。green 与 gangrene 的最后音节共享 /ɡriːn/ 音，tangerine、serene 共享 /riːn/ 尾音，但重音和元音不同，均不构成整词押韵。
