un-（不）+ substantiate（证实）→未经证实的说法缺乏“实质(substance)”支撑，如同没有骨架的谣言。

发音与拼写Pronunciation & Spelling
与 unsubstantiated 真正押韵的是 substantiated（/səbˈstænʃieɪtɪd/）。其他词虽然都以 -tiated 结尾，但重音元音不同：negotiated /nɪˈɡoʊʃieɪtɪd/、initiated /ɪˈnɪʃieɪtɪd/、satiated /ˈseɪʃieɪtɪd/、differentiated /ˌdɪfəˈrɛnʃieɪtɪd/，只是拼写相似，并不押韵。
