'exactly-updated' is a compound word formed from 'exactly' and 'updated'. 'Exactly' originates from Latin, specifically the word 'exactus', where 'ex-' meant 'out' and 'agere' meant 'to drive'. 'Updated' comes from the word 'update', which is a combination of 'up' and 'date', where 'up' signifies 'to a higher position' and 'date' refers to a specific time.

'exactly' changed from the Latin word 'exactus' and eventually became the modern English word 'exactly'. 'Updated' evolved from the combination of 'up' and 'date' in modern English.

Initially, 'exactly' meant 'completely or entirely', and 'updated' meant 'to bring up to date'. Together, they convey the meaning of being 'precisely brought up to date'.
