Etymology

Origin of incandescent

1785–95; < Latin incandēscent- (stem of incandēscēns ), present participle of incandēscere to glow. See in- 2, candescent

Explanation

When heated, coals become incandescent, which means that they glow red-hot. You could also describe a brilliant and moving novel as incandescent. Incandescent, like the word candle, has its origins in the Latin word candere meaning "to glow or shine." Combined with the suffix in meaning "within," its meaning can be easily pulled from the combination of its root words: "to glow or shine from within." Fire crackers are incandescent because they give off brilliant lights when heated, but look up at a blazing fireworks display, and you'll find it's quite moving, or incandescent with intensity and brilliance.
