IPA: /rɪˈvɜːrsl/
KK: /rɪˈvɜrsəl/
A change that goes in the opposite direction or a situation that is turned around, often resulting in a negative outcome.

Reversal → It is formed from "re-" (meaning again) and "vertere" (meaning to turn). The word describes the act of turning something back or changing it to its opposite.
Think of 'turning back' ('vertere') again ('re-') — that's what reversal means.
