What does coruscating mean?
Coruscating describes something that dazzles — literally with flashes of light, or figuratively through brilliance of wit, intellect, or style. A coruscating speaker is scintillating and quick; a coruscating performance is electrifying. Curiously, the word carries a second, almost opposite sense, particularly in British usage: a coruscating review or attack is one that is scathingly severe. This duality arises because the underlying idea of flashing, darting light came to be applied metaphorically both to glittering brilliance and to the cutting flash of harsh criticism. Derived from the Latin verb coruscari, meaning to flash or quiver, the word entered English in the early seventeenth century alongside its noun coruscation. It remains a formal, literary term prized by reviewers and essayists for its energy and precision, though its double meaning demands careful attention to context so that praise is never mistaken for condemnation.

Etymology of coruscating
Coruscating derives from the Latin verb coruscari, meaning to flash, gleam, or quiver, itself rooted in the adjective coruscus ('flashing, moving quickly'). The word entered English in the early seventeenth century, initially in its literal sense of flashing or sparkling, together with its sibling noun coruscation. Over time it developed figurative uses for intellectual and stylistic brilliance, and in British English an additional sense describing harshly critical prose. It has no widely known English cousins outside its own small family of forms, as the Latin root coruscus yielded few borrowings.
