'exactly-located' originates from the combination of 'exactly' and 'located', where 'exactly' means 'in a precise manner' and 'located' means 'situated or positioned'.

'exactly' and 'located' have been used in English since the late Middle Ages, and their combination into 'exactly-located' is a modern construct to emphasize precision in location.

Initially, 'exactly' and 'located' were used separately, but their combination emphasizes precision in modern usage.
