Fire is the bright, hot flames that happen when something burns, giving off light and heat. As a verb, it can mean to shoot a weapon or to dismiss someone from a job.
It comes from Old English “fyr,” from a very old Indo-European root related to heat and burning. The word has always been central to human life and survival.
Fire is not a thing you can hold; it’s a process—a chemical reaction we turned into a symbol of warmth, danger, and even inspiration. Calling someone “fired up” borrows the image of flames to describe emotional energy.
