Did You Know?

Adjective

Incandescent came into the English language toward the end of the 18th century, at a time when scientific experiments involving heat and light were being conducted on an increasingly frequent basis. An object that glowed at a high temperature (such as a piece of coal) was "incandescent." By the mid-1800s, the incandescent lamp - a.k.a. the "lightbulb" - had been invented; it contains a filament which gives off light when heated by an electric current. "Incandescent" is the modern offspring of a much older parent, the Latin verb candēre, meaning "to glow." Centuries earlier, the word for another source of light, "candle," was also derived from "candēre."
