记忆技巧Memory Tip
记忆联想（非词源）：de- 有“去掉”的感觉，sensitive 是“敏感”，连起来像“把敏感去掉”——脱敏、使麻木。
语境与语域Context & Register
语域：mixed 常见场景：medical treatment、psychology、figurative use 在医学和心理学语境中通常较正式，多用于专业描述；在日常比喻用法中则比较中性。该词常与介词 to 连用，表示对某事物不再敏感。
发音与拼写Pronunciation & Spelling
真正押韵：sensitize /ˈsensɪtaɪz/，其重读音节及后续读音 /ˈsensɪtaɪz/ 与 desensitize /diːˈsensɪtaɪz/ 的重读音节及后续读音 /ˈsensɪtaɪz/ 相同。拼写相似但读音不同：realize、organize、recognize、apologize、criticize 都以 -ize 结尾，最后都读 /aɪz/，但重读元音不同，因此不与 desensitize 押韵。
