'deride' originates from Latin, specifically the word 'deridere,' where 'de-' meant 'down' and 'ridere' meant 'to laugh.'

'deridere' transformed into the French word 'derider,' and eventually became the modern English word 'deride' through Middle English.

Initially, it meant 'to laugh down at someone,' but over time it evolved into its current meaning of 'to ridicule or mock someone or something.'
