'exactly-resolved' originates from the combination of 'exactly' and 'resolved', where 'exactly' means 'in a precise manner' and 'resolved' means 'determined or solved'.

'exactly' and 'resolved' have been used separately in English since the 14th century, and their combination into 'exactly-resolved' is a modern construct to emphasize precision in resolution.

Initially, 'resolved' meant 'to loosen or release', but over time it evolved into its current meaning of 'solved or determined'.
