A flash of inspiration
Meaning
A sudden, brilliant, and often unexpected new idea or solution to a problem.
Origin
The phrase marries the ancient concept of 'inspiration'—once believed to be a divine breath or the influence of a muse—with the vivid imagery of a sudden 'flash' of light. As the Enlightenment ushered in an era where creative breakthroughs were increasingly seen as internal mental events rather than supernatural intervention, the metaphor shifted. By the 19th century, the instantaneous and illuminating nature of a new idea was likened to a sudden burst of light, like lightning striking. This phrase perfectly captures that moment when a complex problem is suddenly illuminated, or a novel concept springs fully formed into the mind, a bright spark igniting understanding from nowhere.
