Did you know?

The word fireworks burst upon the scene in the 1500s as a reference to military explosives (a sense that is now obsolete). These explosives were originally used as weapons, of course, but soon they were also being used in explosive displays celebrating victory or peace. By 1575 people were oohing and aahing over "fireworks shewed upon the water; the which were both strange and wel [sic] executed." Figurative uses have been popping up ever since the 1600s. In addition to the angry explosion sense, fireworks can also refer to a spectacular display of musical, visual, or verbal brilliance, as in "an outstanding album, bursting with spectacular musical fireworks."
