za'farān

Saffron comes from Arabic za'farān (زعفران), likely meaning 'yellow' or related to the yellow color the spice produces. The spice itself is the dried stigma of Crocus sativus—each flower produces only three tiny red threads, and it takes roughly 75,000 flowers to make a single pound of saffron. This staggering labor is why saffron has been the world's most expensive spice for three millennia.

The crocus probably originated in Bronze Age Crete or Persia. A Minoan fresco from 1600 BCE shows saffron gatherers at work—making it one of the oldest continuously cultivated crops. The Persians used it for dye, medicine, perfume, and offerings to the gods. Alexander the Great is said to have bathed in saffron-infused water.

Arab traders spread both the spice and the word across the Mediterranean. Za'farān entered Medieval Latin as safranum, Old French as safran, and English as saffron by the 1200s. The word arrived in England before the spice was grown there—saffron cultivation began in Essex in the 1300s, giving the town of Saffron Walden its name.

Today, Iran produces roughly 90% of the world's saffron. The price—$5,000 to $10,000 per pound—makes it a target for adulteration. Turmeric, safflower, and even dyed corn silk are sold as 'saffron' to the unwary. The most expensive spice is also the most frequently faked.
