"WebThe word chemistry derives from the word alchemy, which is found in various forms in European languages. Alchemy derives from the Arabic word kimiya (كيمياء) or al-kīmiyāʾ (الكيمياء).The Arabic term is derived from the Ancient Greek χημία, khēmia, or χημεία, khēmeia, 'art of alloying metals', from χύμα (khúma, “fluid”), from χέω (khéō, “I pour”).
