coruscate

To help you gain a flash of recognition next time you see coruscate (or to prompt you when you need a brilliant synonym for sparkle), remember this bit of bright imagery by George Bernard Shaw, describing a centuries-old abbey: "O'er this north door a trace still lingers / Of how a Gothic craftsman's fingers / Could make stones creep like ivy stems / And tilings coruscate like gems." Or you could just remember that coruscate developed from Latin coruscare, which means "to flash." That word also gave us the noun coruscation ("glitter" or "sparkle") and the adjective coruscant ("shining" or "glittering").
