In the history of science, the etymology of the word chemistry is debatable. It is agreed that the word derives from the word alchemy, which is a European one, derived from the Kimiya (کیمیا) Alchemy al-kīmiyāʾ (الكيمياء). The Arabic term is derived from the Ancient Greek χημία khēmia or χημεία khēmeia.[1][2] However, the ultimate origin of the root word, chem, is uncertain.[3]
