'differ' originates from Latin, specifically the word 'differre,' where 'dis-' meant 'apart' and 'ferre' meant 'to carry.'

'differre' transformed into the Old French word 'differer,' and eventually became the modern English word 'differ' through Middle English.

Initially, it meant 'to carry apart or separate,' but over time it evolved into its current meaning of 'to be unlike or distinct.'
