'evacuation' originates from Latin, specifically the word 'evacuatio,' where 'e-' meant 'out' and 'vacuare' meant 'to empty.'

'evacuatio' transformed into the Old French word 'évacuation,' and eventually became the modern English word 'evacuation' through Middle English.

Initially, it meant 'to empty out,' but over time it evolved into its current meanings of 'removal of people from danger' and 'emptying of contents.'
