'alchemise' originates from the Arabic word 'al-kīmiyā', where 'al-' meant 'the' and 'kīmiyā' meant 'philosopher's stone or elixir'.

'al-kīmiyā' transformed into the Old French word 'alquemie', and eventually became the modern English word 'alchemy', from which 'alchemise' is derived.

Initially, it meant 'to transform base metals into gold', but over time it evolved into its current meaning of 'to transform something in a mysterious way'.
