'accursed' originates from Middle English, specifically the word 'acursed,' where 'a-' meant 'intensive' and 'cursed' meant 'under a curse.'

'acursed' changed from the Old English word 'acursian' and eventually became the modern English word 'accursed.'

Initially, it meant 'intensely cursed,' but over time it evolved into its current meaning of 'under a curse.'
