Final answer:
The word 'discursive' refers to a style of speech or writing that wanders from topic to topic, which is not captured by any of the provided options. It is often lengthy and explores various aspects of a subject, rather than being focused and concise.
Step-by-step explanation:
The word 'discursive' pertains to discourse or modes of communication that are rambling or wandering from subject to subject. In the context of the options provided, 'discursive' is often characterized by a lengthy, wandering style, rather than being focused and concise. Therefore, none of the provided choices accurately define 'discursive'; a more appropriate definition would be 'rambling or digressive'. Discursive speech or writing moves from topic to topic and often provides a detailed exploration of various aspects of a subject.
For instance, in a discursive essay, a writer might explore different facets of a topic, incorporating personal reflections, contrasting viewpoints, and an interwoven narrative that may not always adhere strictly to a single point. It can be informative and engaging, yet it generally lacks the precision and brevity of focused and concise writing. Likewise, in a discursive speech, the speaker may meander through different examples or anecdotes, providing a broad but not always linear discussion of the subject.
