'exactly-given' originates from the combination of 'exactly' and 'given', where 'exactly' comes from Latin 'exactus', meaning 'precisely', and 'given' is the past participle of 'give', from Old English 'giefan'.

'exactly' evolved from the Latin 'exactus' through Middle English 'exact', and 'given' from Old English 'giefan', forming the modern English compound 'exactly-given'.

Initially, 'exactly' meant 'precisely' and 'given' meant 'bestowed', and together they convey the idea of something provided with precision.
