Did you know?

At first hazard was a game of chance played with dice. The English word comes from medieval French, in which the game was called hasard. This French word was probably borrowed from Arabic az-zahr, meaning “the dice” or “one of the dice.” The game was borrowed from the French by the English, and within a few centuries what had been a chance taken on the outcome of a throw of the dice could be any venture or risk. Now “chance” or “venture” and “risk” or “peril” are the usual meanings of hazard. The verb hazard emerged in the 16th century.

Etymology

Noun

Middle English hazard "game of chance," from early French hasard (same meaning), from Arabic az-zahr "the die (one of the dice)"

Word Origin

Hazard was at first a game of chance played with dice. The English word comes from an early form of French, in which the game was called hasard. This French word was probably borrowed during the time of the Crusades from Arabic az-zahr, meaning "the die (one of the dice)." The game was borrowed from the French by the English, and within a few centuries, what had been a chance taken on the outcome of a throw of the dice could be any venture or risk. Now "chance" or "venture" and "risk" or "peril" are the usual meanings of hazard.
