'precisely-handled' originates from the combination of 'precisely' and 'handled', where 'precisely' comes from Latin 'precisus', meaning 'cut off, brief', and 'handled' from Old English 'handlian', meaning 'to touch or manage'.

'precisely' evolved from the Latin 'precisus' through Old French 'precis', and 'handled' from Old English 'handlian', eventually forming the modern English compound adjective 'precisely-handled'.

Initially, 'precisely' meant 'briefly or concisely', but over time it evolved to mean 'exactly or accurately', while 'handled' has retained its meaning of 'managed or dealt with'.
