Learner notes
Memory Tip

Context & Register
语域：formal 常见场景：法律或合同文书、学术或正式论述 vitiate 是正式用语，多用于书面或正式场合，常见于法律、学术或抽象论述中，表示“损害”“削弱”或“使无效”；日常口语中较少使用。
Pronunciation & Spelling
真正与 vitiate（/ˈvɪʃieɪt/）押韵的是 initiate 和 officiate：它们的重读音节都是 -tiate 前面的 /ɪ/，韵脚同为 /ɪʃieɪt/。negotiate、associate、appreciate、satiate 也以 -tiate 结尾，但重读元音分别是 /oʊ/、/oʊ/、/iː/、/eɪ/，所以不押韵，只是拼写相似。
