Coruscate -- to sparkle in technique or style

From Honor Moore's remarkable remembrace of her father, the late Episcopal Bishop Paul Moore, in this week's New Yorker: "When I was a child, I accepted my father as a force of imagination that flared and coruscated, and instrument of transformation."

coruscate verb [from the Latin coruscare to flash]
1: to give off or reflect light in bright beams or flashes: sparkle
2: to be brilliant or showy in technique or style

Ms. Moore's story is powerful reading for the dozen or so Grammar Tip of the Day recipients who remember Bishop Moore so well and so fondly from our years growing up on the Washington Cathedral Close.
Among many other facets of Honor Moore's incredible piece of writing is a reminder of her father's vision of and commitment to an urban ministry, as described so well in Mrs. Moore's memoir, The People of Second Street, about their years, starting in 1949, at a parish in lower Jersey City, as Honor Moore describes it, "a gritty neighborhood blocks from where On the Waterfront was filmed, four years later."
