'definitively' originates from Latin, specifically the word 'definitivus,' where 'definire' meant 'to set bounds or limits.' 'Collected' comes from Latin 'collectus,' the past participle of 'colligere,' meaning 'to gather together.'

'definitivus' transformed into the Old French word 'definitif,' and eventually became the modern English word 'definitive.' 'Collectus' evolved into the Old French 'collecter,' leading to the modern English 'collect.'

Initially, 'definitive' meant 'serving to define or specify,' but over time it evolved into its current meaning of 'conclusive and final.' 'Collect' has largely retained its original meaning of 'gathering together.'
