الزهر
az-zahr
Arabic
“A dice game played by Crusaders in an Arab castle gave English its word for danger.”
The Arabic word az-zahr (الزهر) meant 'the die' or 'the dice'—and by extension, a game of dice. During the Crusades, European soldiers encountered dice games in the Levant and became addicted to them. The word entered Old French as hasard, meaning a dice game—pure chance, no skill involved.
William of Tyre, the 12th-century chronicler, claimed the word came from a castle called Hazart where Crusaders gambled during the siege of a fortress. Whether this is true or folk etymology, the association between the Arabic word and gambling was fixed by the 1200s.
From gambling, the meaning broadened. Anything involving chance was a hazard. Anything involving risk was a hazard. By the 1500s, the word had darkened from 'game of chance' to 'danger' and 'peril.' The playfulness of dice was forgotten; only the risk remained.
English now uses hazard almost exclusively to mean danger—hazardous materials, occupational hazards, hazard warnings. The dice game that gave the word its start is extinct. But every time we identify a hazard, we're naming a danger with a word that originally meant 'roll the dice and see what happens.'

Every safety sign that says HAZARD is unknowingly referencing a medieval dice game. The word traveled from playful gambling to mortal danger in five centuries.
But the original meaning lingers in the concept: a hazard is still fundamentally about chance—the unknown outcome, the roll you can't control. Whether it's a dice game or a chemical spill, hazard names the moment when outcome leaves your hands.
