noun
Evacuation — the organized act of leaving a place for protection from danger
Definition
The act of evacuating; leaving a place in an orderly fashion; especially for protection
In depth
Evacuation is the act of evacuating, leaving a place in an orderly fashion, especially for protection from imminent danger such as natural disaster, fire, or military threat. The word implies coordination and urgency together, a departure that must happen quickly yet remain organized enough to keep people safe.
Origin
The word descends from Latin evacuare, to empty out, formed from ex- (out) and vacuus (empty) — the same root behind 'vacuum' and 'vacant.' That image of emptying remains literal in the word's modern use: an evacuation leaves a place entirely vacant, cleared deliberately of everyone who had occupied it.
Usage examples
"The evacuation proceeded smoothly, thanks to drills the residents had practiced every year without fail."
"Hospital staff coordinated the evacuation of every patient hours before the floodwaters arrived."
"The town's evacuation, ordered just before dawn, left streets eerily empty by midmorning."
How to use it
Evacuation is essential vocabulary in disaster, emergency, and military writing, valuable for conveying both urgency and necessary order, the careful balance between speed and safety that distinguishes true evacuation from chaotic flight.
