fire-and-brimstone

The phrase "fire and brimstone" is a fixed English idiom originating from biblical language, most famously used in the King James Version to describe the divine punishment of Sodom and Gomorrah. Its components are native English words: "fire," from Proto-Germanic, and "brimstone," an Old English compound meaning "burning stone" for sulfur, a substance associated with volcanic eruptions and foul odors. The conjunction "and" links these two potent symbols of destruction and purification. Over time, the literal description of a cataclysmic event evolved into a metaphorical adjective characterizing any vehement, threatening rhetoric that warns of severe consequences, particularly of a religious or moral nature.
