A stroke of genius
Meaning
An extremely clever and original idea or action that solves a problem or achieves a goal effectively.
Origin
The word "stroke" has long been associated with sudden, impactful actions—a "stroke of a brush," a "stroke of luck," or even a "stroke of a pen" to sign a decree. When this idea of a swift, decisive act merged with the concept of "genius," which by the 19th and early 20th centuries had solidified into the notion of extraordinary intellectual ability and creative power, the phrase "a stroke of genius" was born. It vividly describes that precise, often unexpected moment when an exceptional mind produces a brilliant idea or solution, making it seem less like arduous effort and more like a sudden, inspired flash of pure brilliance, almost as if divinely bestowed.
