Discursive
Discursive 是一个形容词。在负面意义上，指文章或谈话主题不集中，跑题；在哲学语境中，指通过逻辑推理得出结论的过程。
- The book is a bit too discursive and would benefit from some editing. (这本书有点太散漫了，如果能进行一些剪辑会更好。)
- Her speech was long and discursive, touching on many unrelated topics. (她的演讲冗长且散漫，涉及了许多无关的主题。)
- Scientific reasoning is a discursive process. (科学推理是一个逻辑推论的过程。)
- 词根：
-curs-(跑，如 current, course) - 前缀：
dis-(到处/散开) - 含义：到处乱跑 -> 散漫/跑题。
联想 discuss (讨论)。Discursive 就是那种像漫无目的的“讨论”一样到处跑题的状态。或者记：dis- (散开) + course (路线)。
The professor’s discursive lectures were interesting but made it hard to take structured notes. (教授那东拉西扯的讲座很有趣，但很难记下有条理的笔记。)
