下句總共使用了 11 個 that，其中 7 個還連在一起，但它仍是個有意義且語法正確的句子 (以下稱為「本句」)。本句不僅以實例來呈現 that 的不同用法，而且使用 “it’s true (that)” 句型來說明，儘管都是 that，但吾人不能一體適用地看待所有 that 或任何 that，因為此 that 往往非彼 that。
It is true for all that that that that that that that refers to is not the same that that that that refers to.
現在就來說明這 11 個 that 在句中的詞類和用法。為了避免混淆，筆者依序在它們的後面加上阿拉伯數字。
It is true for all that1 that2 that3 that4 that5 that6 that7 refers to is not the same that8 that9 that10 that11 refers to.
誠如上述，本句使用了 “it’s true (that)” 句型，句中引導名詞子句的連接詞 that 可以省略。本句的 that1 為代名詞，而 that2 就是引導 “that that that that that refers to is not the same that that that that refers to ” 這整個名詞子句的連接詞。
That3 所代表的 that 為限定詞 (用法與 a, the, this 等限定詞一樣) 或形容詞，係用來限定或修飾當名詞用的 that4，而 that5 為關係代名詞，可用 which 來代替。至於 that6 和 that7，則與 that3 和 that4 一樣，前者為限定詞或形容詞，後者為名詞。
在另一由 4 個 that 所構成的組合中 (即 that8、that9、that10 和 that11)，that8 為名詞，that9 為關代，同樣可用 which 來代替，而 that10 和 that11 則分別為限定詞和名詞。
所以，本句可改寫成下句，其中當名詞用的 that 都加上了引號。
It is true, for all that, that that “that” which that “that” refers to is not the same “that” which that “that” refers to. (儘管都是 that，但那個 that 所指的那個 that 與那個 that 所指的 that 的確不是同一個 that)
如果您堅持語法要百分之百正確、毫無瑕疵，那麼可以將句末的介系詞 to 挪到關代的前面，即
It is true, for all that, that that “that” which that “that” refers to is not the same “that” to which that “that” refers.
