Learner notes
Memory Tip
substantiate 像 substance（实质）+ ate，让说法有实质内容，即‘证实’。想象给一句话填上实质证据。
Context & Register
语域：formal 常见场景：艺术评论、文学分析、哲理论述 该词通常用于正式书面语，多出现在文艺评论、哲理论述等语境，表示‘使抽象事物具体化、坚实或更有分量’；日常口语中很少用。
Pronunciation & Spelling
这些词都与 substantiate 一样以 -iate 结尾，但多数重读元音不同，因此并不都与 substantiate 押韵。其中 associate 和 negotiate 彼此押韵（均含 /oʊʃieɪt/）；initiate、appreciate、differentiate、enunciate 则各有不同元音。真正与 substantiate 押韵的词要含 /stænʃieɪt/，如较生僻的 transubstantiate。别只看拼写就断定发音相同。
