Did You Know?
Need a shiny word to bust out at your next disco party, planetarium visit, or fireworks gathering? How about effulgence? It’s not a shiny “new” word, having made its English language debut in the 17th century, but it’s unusual and has a lovely Latin pedigree: the verb fulgēre, meaning “to shine.” Effulgence isn’t used for bog-standard brightness, however; it’s reserved for shininess that dazzles, inspires, leaves you gobsmacked—in other words, “radiant splendor.”
