What does the term discursive refer to in relation to speech or writing?

The term "discursive" in relation to speech or writing describes a style that covers a wide range of subjects or moves from one topic to another in a somewhat free or expansive manner. Typically, discursive writing or speech is characterized by its exploratory nature, often taking the reader or listener through various related themes and ideas rather than sticking rigidly to a single point or maintaining a strict argumentative structure. This can encourage a deeper investigation of a topic, though it may also lead to a more diffuse or less focused exposition.

The focus on breadth rather than brevity indicates that discursive expression will embrace complexity and a mixture of ideas, which is why "covering a wide range of subjects" aptly encapsulates its essence. This makes the chosen answer particularly fitting as it highlights the expansive approach inherent in discursive forms.
