'amass' originates from Old French, specifically the word 'amasser,' where 'a-' meant 'to' and 'masse' meant 'mass or heap.'

'amasser' changed from the Old French word 'amasser' and eventually became the modern English word 'amass.'

Initially, it meant 'to gather into a mass or heap,' but over time it evolved into its current meaning of 'to collect or gather in large quantities.'
