What does alchemy mean?
Alchemy was a philosophical and proto-scientific tradition practiced from antiquity through the early modern period, blending practical chemistry with mystical and spiritual ideas. Its central ambitions were the transmutation of base metals such as lead into gold, the discovery of a universal elixir capable of curing disease and extending life, and the purification or perfection of matter itself. Practitioners developed laboratory techniques, apparatus, and processes — distillation, sublimation, calcination — that later fed directly into the emergence of modern chemistry, even though alchemy's theoretical framework ultimately proved unscientific. In contemporary English, 'alchemy' survives chiefly as a vivid metaphor: we speak of the alchemy of a great performance, a successful business venture, or a memorable meal, meaning some seemingly magical combination of elements that produces results greater than their parts. The word thus carries connotations of mystery, transformation, and inspired craft, making it a rich and evocative term for describing creative or inexplicable achievement.
nounA medieval chemical science and speculative philosophy that sought to transform base metals into gold and to discover a universal cure for disease and means of prolonging life; by extension, any seemingly magical process of transformation or combination.
- The medieval practice and philosophy combining elements of chemistry, metallurgy, astrology, and mysticism, aimed especially at transmuting base metals into gold and finding an elixir of life.
- A seemingly miraculous or mysterious process of transformation or creation (used figuratively).
"The chef described her cooking as a kind of alchemy, turning humble ingredients into something extraordinary."
"Medieval alchemy blended laboratory experimentation with mystical beliefs about the transformation of matter."
"The novelist's prose works like alchemy, transforming ordinary scenes into moments of wonder."
'Alchemy' is usually uncountable when referring to the general practice. A plural form appears mainly when discussing multiple distinct traditions or schools of alchemy, such as Chinese, Indian, and European alchemy.
"Scholars have compared the alchemies of China, India, and medieval Europe."
For centuries, alchemists chased the secret of turning lead into gold — and in doing so accidentally laid the foundations of modern chemistry.

Etymology of alchemy
The word 'alchemy' entered Middle English in the late Middle Ages via Old French 'alquemie' and Medieval Latin 'alchimia', which derived from Arabic 'al-kīmiyāʾ' — itself likely borrowed from Greek 'khēmeia' or related to 'khuma', the Greek name for Egypt, long associated with metallurgy and dyeing. The Arabic definite article 'al-' ('the') became fused into the European word, as it did in other borrowings such as 'algebra' and 'alcohol'. Its sibling discipline, chemistry, shares this lineage: both trace back to the same Greco-Arabic root, with 'chemistry' emerging later as the scientific successor to alchemy.

How alchemy is actually used
In modern usage, 'alchemy' is most often figurative, describing any impressive or inexplicable transformation — in art, business, cooking, or relationships. The literal historical sense is typically encountered in discussions of medieval history and the history of science. The word carries connotations of mystery, magic, and almost-miraculous skill; it is generally positive or admiring rather than pejorative.
Easily confused with alchemy
Chemistry is the modern, evidence-based science of substances and their reactions, whereas alchemy was its pre-scientific precursor entangled with mysticism and the quest for gold and immortality.
