Etymology: Sedulous is one of those English words whose original sense was almost the reverse of a modern reader's guess. It comes from Latin "sēdulus," meaning diligent or industrious, and that Latin adjective was built on "sēdulō," an adverb meaning diligently, carefully, or zealously. The adverb's own origin is uncertain. One suggestion splits it into "sē-," meaning "without," and "dolō," the ablative of "dolus," meaning deceit or evil intent, which would make the root sense something like "without guile." Readers should treat that as a possibility rather than settled fact, since the link is not firmly established. English took the adjective in its Latin form and added the common "-ous" ending, which turns a noun or adjective into a description of a quality. The meaning stayed close to its roots throughout: a sedulous person works steadily and persistently at a task rather than dashing at it briefly. The emphasis is on sustained, careful effort, which is why the word tends to appear with phrases like "sedulous attention" or "sedulous care."
