'discount' originates from the Latin word 'discomputare,' where 'dis-' meant 'apart' and 'computare' meant 'to count.'

'discomputare' transformed into the Old French word 'descompter,' and eventually became the modern English word 'discount' through Middle English.

Initially, it meant 'to count apart or deduct,' but over time it evolved into its current meaning of 'a reduction in price.'
