Memory Tip
记法：inter（之间）+ media（中间）→ 夹在两者之间的东西，如中间产物或中间人。联想“互联网”也是连接之间的媒介。
Context & Register
语域：formal 常见场景：technical writing、chemistry、automotive industry 作为名词时，intermediate 多用于书面语和专业领域，比如化学、汽车尺寸或轮胎分类；日常口语中较少单独使用。表示“中间人”时也偏正式，口语中常改用 intermediary 或 middleman。
Pronunciation & Spelling
真正押韵的词：immediate /ɪˈmiːdiɪt/（与 intermediate 一样，重音后的 /diɪt/ 相同）。拼写上的形近词如 mediate /ˈmiːdieɪt/、associate /əˈsoʊʃieɪt/、negotiate /nɪˈɡoʊʃieɪt/ 都以 -iate 结尾，但读作 /ieɪt/，与 intermediate 的 /iɪt/ 韵尾不同，注意不要混淆。
