Why “operosity” is a great word
Operosity is the quality of being painstaking and involving great, often arduous, effort. From Latin *operōsitās* ("laboriousness"), from *operōsus* ("laborious, industrious"), from *opus* ("work"). Unlike "diligence," which implies a steady, earnest application, or "tedium," which names the monotony it begets, operosity is the stark acknowledgment of a task's inherent toilsomeness. It is the grit of the scribe illuminating a vellum manuscript by candle-glow, the measured, backbreaking rhythm of quarrying stone by hand, and the silent, minute labor of restoring a faded masterpiece—the quiet tax extracted by any creation built grain by resistant grain.
