'discount' originates from Latin, specifically the 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 'reduce in price or value.'
