'deferrer' originates from the Latin 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 'defer' through Middle English.

Initially, it meant 'to carry apart or delay,' but over time it evolved into its current meaning of 'to postpone or delay.'
