Context & Register
语域：mixed 常见场景：医学/生理描述、正式书面语（dilate on/upon） 该词语域随搭配和场景变化：表示“变宽、变大”时多用于医学或科学等客观描述，语气比较正式；与 on/upon 连用表示“详述”时通常只见于正式书面语。日常口语中较少使用，更口语化的说法是 get bigger/wider。
Pronunciation & Spelling
与 dilate 押韵（/eɪt/）：late、rate、date、translate。注意：private 和 climate 虽也以 -ate 结尾，但分别读作 /ˈpraɪvɪt/ 和 /ˈklaɪmɪt/，发音不同，不能与 dilate 押韵。
