unsubstantiated 是形容词，作表语时前面必须加系动词 be；汉语可以说“这些说法未经证实”，但英语形容词不能单独作谓语，所以应加上 are。
The accusations are unsubstantial.The accusations are unsubstantiated.
unsubstantial 意为“不结实的；不牢固的；不实在的”，而 unsubstantiated 才表示“未经证实的、没有证据支持的”。这里是形容词词义混淆，应改用 unsubstantiated。

Learner notes
Memory Tip
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。
Context & Register
语域：formal 常见场景：正式写作、新闻报道、学术论述 unsubstantiated 比较正式，多用于书面语或正式场合，表示“未经证实的、没有根据的”；日常口语中更常说 without evidence 或 not proven。
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。
