Etymology

Origin of firework

First recorded in 1550–60; fire + work

Explanation

Fireworks are small explosive devices that produce colorful, glittering lights in the night sky. A typical July Fourth fireworks display uses hundreds of individual fireworks. The word fireworks, coined in the 16th century, is usually plural, whether it's referring to the device itself or a show featuring the brilliant, noisy bursts of colored light. You might ask a friend on New Year's Eve, "Are you going to see the fireworks tonight?" Figuratively, the word is perfect for describing a heated clash or conflict: "There's always fireworks when those two start arguing about politics!"
