'precisely' originates from Latin, specifically the word 'praecisus,' where 'prae-' meant 'before' and 'caedere' meant 'to cut.' 'Control' originates from Latin, specifically the word 'contrarotulare,' where 'contra-' meant 'against' and 'rotula' meant 'roll.'

'precisely' changed from the Old French word 'precis' and eventually became the modern English word 'precise.' 'Control' transformed from the Old French word 'contrerole' and eventually became the modern English word 'control.'

Initially, 'precisely' meant 'cut short or concise,' but over time it evolved into its current meaning of 'exactly.' 'Control' initially meant 'to check or verify,' and this meaning has largely remained the same in modern usage.
