IPA: /ˈɛərˌbɜrst/
KK: /ˈɛrˌbɜrst/
A type of explosion that occurs in the air, typically from a bomb or shell, rather than on the ground.
The airburst of the bomb caused widespread damage over a large area.
Airburst is formed from "air" (from Old English "aer", meaning the invisible gaseous substance surrounding the earth) and "burst" (from Old English "berstan", meaning to break open or explode). The word describes an explosion that occurs in the air rather than on the ground.
Imagine an explosion that happens in the 'air' — that's why 'airburst' refers to a burst that occurs in the atmosphere.
