'derive' originates from Latin, specifically the word 'derivare,' where 'de-' meant 'down from' and 'rivus' meant 'stream.'

'derivare' transformed into the Old French word 'deriver,' and eventually became the modern English word 'derive' through Middle English.

Initially, it meant 'to lead or draw off a stream,' but over time it evolved into its current meaning of 'to obtain something from a source.'
