Memory Tip
记住 electrode 像 electric road（电路之路）：电极就是电流进出的路。
Context & Register
语域：formal 常见场景：电化学、电子工程、医学检测 electrode 属于技术性词汇，通常用于电化学、电子工程、医疗检测等专业或正式语境；日常口语中较少出现，多写作书面语。
Pronunciation & Spelling
code, node, mode, and rode rhyme with one another, all sharing the stressed /oʊd/ sound. Electrode, however, is /ɪˈlɛktroʊd/, with stress on /ɛk/, so these -ode words do not rhyme with it. Cathode and anode are related technical lookalikes, but their final syllables are /θoʊd/ and /noʊd/ and their stress falls earlier, so they do not rhyme with electrode either.
