الكيمياء
al-kīmīyāʾ
English from Arabic from Greek
“The quest to turn lead into gold gave us the word for all transformation.”
Alchemy's etymology is itself a transformation. The Arabic al-kīmīyāʾ combines the Arabic article al- with a root that might come from Greek khemeia (the art of transmutation) or from Khem, an ancient name for Egypt—"the Egyptian art."
Arab scholars preserved and expanded Greek alchemical knowledge during the Islamic Golden Age. Jabir ibn Hayyan (Geber) developed experimental methods that would become the foundation of chemistry. His Arabic texts were the standard for centuries.
When Europeans translated these Arabic works in the 12th century, they kept the Arabic article al-. Chemistry later dropped the article; alchemy kept it—the al- marking the older, more mystical pursuit.
The split between alchemy (mystical transformation) and chemistry (scientific analysis) happened gradually. Newton was an alchemist. Boyle was both. The same Arabic word gave birth to both the magic and the science.

Alchemy is now used metaphorically for any seemingly magical transformation: "the alchemy of cooking," "emotional alchemy," "the alchemy of great writing."
The word carries a residue of the mystical—even though alchemy's methods became chemistry's methods. The al- prefix still marks it as something older, stranger, less tame than science.
Every time we use alchemy metaphorically, we're acknowledging that some transformations feel like magic even when they're not.
