'precisely' originates from Latin, specifically the word 'praecisus,' where 'prae-' meant 'before' and 'caedere' meant 'to cut.' 'Tuned' comes from the Old English 'tune,' meaning 'a musical sound.'

'precisely' changed from the Latin word 'praecisus' and eventually became the modern English word 'precisely.' 'Tuned' evolved from the Old English 'tune' to the modern English 'tuned.'

Initially, 'precisely' meant 'cut off or shortened,' but over time it evolved into its current meaning of 'exactly or accurately.' 'Tuned' has largely retained its original meaning related to musical sound.
