'ajoure' originates from French, specifically the word 'ajouré,' where 'a-' meant 'to' and 'jour' meant 'day' or 'light.'

'ajouré' changed from the French word 'ajouré' and eventually became the modern English word 'ajoure'.

Initially, it meant 'to let light through,' but over time it evolved into its current meaning of 'decorated with openwork patterns or designs.'
