She insisted that that that isn't that that. 的中文意思

She insisted that that "that" isn't that "that".

她坚持说，她说的意思，不是别人所理解的那个意思。

本句中共5个that

第3个that指“她”的原意

第5个that指“别人”理解的意思

她坚持事情不是那样的

她强调那个那事不是那个那事.

就是我们常说的这个不是这个,那个不是那个的意思..不好讲清楚啊

其实这句很简单，只要会断句就行了。不过要翻译还要看上下文。
She insisted (that) that "that" isn't that "that".
"that"为名词。

再贴一段 上文来看看

She insisted (that) that "that" isn't that "that".
她坚持认为那个"that" 不同于那个 "that".

这应该是分析句子的一句话，本句中共5个that，第1个that是关系代词引导从句，第3个that和第5个that分别是句子中前后两个词。
