Did you know?

You've read about funeral pyres, and you may even have survived a pyromaniac ("insane fire-starting") stage in your youth, so you might have guessed that pyr means "fire" in Greek. Pyrotechnic refers literally to fireworks, but always seems to be used for something else—something just as exciting, explosive, dazzling, sparkling, or brilliant. The performances of sports stars and dancers are often described as pyrotechnic, and a critic may describe the pyrotechnics of a rock guitarist's licks or a film's camerawork. A pyrotechnic performance is always impressive, but the word occasionally suggests something more like "flashy" or "flamboyant".
