'disadvantaged' originates from the prefix 'dis-' meaning 'not' or 'opposite of' and the word 'advantage,' which comes from Old French 'avantage,' meaning 'advantage, profit, superiority.'

'advantage' changed from the Old French word 'avantage' and eventually became the modern English word 'advantage.'

Initially, it meant 'to have a superior position,' but over time it evolved into its current meaning of 'lacking in resources or conditions.'
