'precisely' originates from Latin, specifically the word 'praecisus,' where 'prae-' meant 'before' and 'caedere' meant 'to cut.' 'Measured' comes from Latin 'mensurare,' meaning 'to measure.'

'precisely' changed from the Old French word 'precis' and eventually became the modern English word 'precise.' 'Measured' evolved from the Old French 'mesurer' and became the modern English 'measure.'

Initially, 'precisely' meant 'cut short' but evolved to mean 'exactly.' 'Measured' has largely retained its meaning of 'determining the size or amount.'
