'precisely-segmented' originates from the combination of 'precisely' and 'segmented'. 'Precisely' comes from Latin 'precisus', meaning 'cut off', and 'segmented' comes from Latin 'segmentum', meaning 'a piece cut off'.

'Precisely' evolved from the Latin 'precisus' through Old French 'precis', and 'segmented' evolved from Latin 'segmentum' through Middle English 'segment'.

Initially, 'precisely' meant 'cut off sharply', and 'segmented' meant 'a piece cut off'. Over time, they evolved to mean 'exactly' and 'divided into parts', respectively.
