IPA: /ˈaʊtˌbɜrst/
KK: /aʊtˌbɜrst/
A sudden and strong expression of emotion or activity, often unexpected and intense.
His outburst of anger surprised everyone in the room.
Outburst → It is formed from "out-" (meaning outside or outward) and "burst" (from Old English "berstan", meaning to break or explode). The word "outburst" describes a sudden breaking forth of emotion or energy from within to the outside.
Think of something breaking forth from the inside to the outside — 'out-' means outward, and 'burst' means to break. This helps you remember that an outburst is a sudden release of emotion.
