Coruscating means shining with bright flashes of light — like sparks, or a surface that keeps glittering. People also use it of a person, a talk, or a piece of writing that feels brilliantly alive: full of energy, wit, or dazzle. It is a rather literary, showy word; you meet it in reviews and careful writing more than in the street. Though actually, some writers say 'a coruscating attack' as if it meant 'very angry and cutting'. That stretches the word toward bitterness. The older, safer meaning is brightness or brilliance, not scolding.

璀璨的、閃耀的；（比喻）才華洋溢、才氣逼人
