语境与语域Context & Register
语域：mixed 常见场景：临床医疗语境、日常口语夸张表达 该词表示“精神错乱的；痴呆的”时，语域随语境变化：正式/医疗描写与口语夸张用法都存在。直接用于人可能显得冒犯；通常口语中更常说 crazy 或 out of one’s mind，医学上常说 with dementia。
发音与拼写Pronunciation & Spelling
All the words above rhyme with 'demented' (/dɪˈmɛntɪd/): they contain the stressed vowel /ɛ/ followed by /ntɪd/ (or /tɪd/ after an n). Be careful with lookalikes such as 'demanded' (/dɪˈmɑːndɪd/) or 'decided' (/dɪˈsaɪdɪd/)—they end in '-ed' but have a different vowel sound, so they do not rhyme.
