What does discursus mean?
"Discursus" is a noun denoting an extended discussion or treatment of a subject — essentially a formal synonym of "discourse", but with an added suggestion of rambling or digressiveness. A writer might describe an essay as a leisurely discursus on memory, meaning that it wanders reflectively rather than advancing point by point toward a conclusion. The word comes directly from Latin, where discursus meant "a running about", from discurrere, "to run to and fro" — the same root that gives us "discursive" and "discourse". Because of this origin, discursus carries an etymological image of thought running in many directions at once. It remains a rare, learned term, found mainly in academic criticism, philosophy, and literary essays, where its slightly Latinate air lends precision and a touch of formality. For readers who enjoy words that name subtle intellectual habits, discursuseful vocabulary: it labels exactly the kind of conversation that will not be hurried.
nounA formal or extended discussion of a subject; a discourse or digressive treatment of a topic.
- An extended, often digressive discussion or treatment of a subject; a discourse.
"The essay unfolds less as an argument than as a leisurely discursus on the nature of memory."
"Her lecture was less a systematic argument than a wide-ranging discursus through centuries of musical thought."
"The chapter opens with a brief discursus on Roman road-building before returning to its main subject."
Both "discursuses" and the unchanged Latin plural "discursus" are attested; both are rare, so writers often avoid the plural altogether.
"The book collects his scattered discursuses on art, music, and travel into a single volume."
Borrowed straight from Latin without changing a single letter, "discursus" is what happens when a conversation refuses to stay on course — and English kept it around precisely because no common word says it quite so well.

Etymology of discursus
"Discursus" entered English directly from Latin, where it was the past participle noun of discurrere, meaning "to run about" or "to run in different directions", formed from dis- ("apart") and currere ("to run"). In Latin it could mean both physical running about and, figuratively, a ranging discussion. English adopted it in learned use as a term for a digressive discourse, sharing its root with the far more common "discourse" and "discursive". It remains one of the family's rarer members, preserved chiefly in scholarly writing.
