Why this word is great
CORUSCATE — [Verb] To emit vivid flashes of light; to sparkle or gleam brilliantly. From Latin coruscātus, past participle of coruscāre ("to vibrate, flash, glitter"). Unlike "scintillate" (which suggests playful, rapid flickers) or "glimmer" (which implies a faint, hesitant shimmer), "coruscate" speaks to a sustained, almost defiant brilliance. It is the diamond catching sunlight in a relentless, blinding dance, the sudden flare of a lighthouse beam slicing through fog, or the way a blade flashes once—decisively—before vanishing into its sheath. Light, at its most urgent, is not merely seen but felt: a brief, bright argument against the dark.
