A bonanza is a situation that creates a sudden increase in wealth, success, or good fortune.
It comes from Spanish “bonanza,” meaning “fair weather” or “calm sea,” from “bono” meaning “good.” In American mining history, it came to mean a rich pocket of ore, then any big stroke of luck.
The word started as good sailing weather and ended up describing gold strikes and game-show jackpots. It captures the feeling that sometimes fortune doesn’t just improve—it explodes in your favor.
