'determine' originates from Latin, specifically the word 'determinare,' where 'de-' meant 'off' and 'terminare' meant 'to mark the end or boundary.'

'determinare' transformed into the Old French word 'determiner,' and eventually became the modern English word 'determine' through Middle English.

Initially, it meant 'to mark the end or boundary,' but over time it evolved into its current meaning of 'to decide or conclude.'
