KK: /ˈroʊlˌoʊvər/
An event where a vehicle turns over onto its side or roof, or the process of transferring funds from one account to another, such as in retirement accounts.
The rollover caused significant damage to the car, but thankfully no one was injured.
Rollover → It is formed from "roll" (from Old English "rollian", meaning to turn over or rotate) and "over" (meaning above or across). The word "rollover" describes the action of something turning over or rotating across a surface.
Imagine something that is 'turning over' ('roll') and moving 'across' ('over') — that's what a rollover means.
