'mitigate' originates from Latin, specifically the word 'mitigare,' where 'mitis' meant 'soft' and 'agere' meant 'to do or make.'

'mitigare' transformed into the Old French word 'mitiguer,' and eventually became the modern English word 'mitigate' through Middle English.

Initially, it meant 'to make soft or gentle,' but over time it evolved into its current meaning of 'to make less severe or intense.'
