IPA: /ˈʃoʊdaʊn/
KK: /ˈʃoʊdaʊn/
A decisive event or confrontation that reveals the outcome of a situation or competition.
The two teams faced each other in a dramatic showdown to determine the champion.
Showdown is formed from "show" (from Old English *sceawian*, meaning to look at or to display) and "down" (from Old English *dūn*, meaning hill or mound). The term originally referred to a decisive confrontation or display of strength, often in a dramatic or confrontational context.
Think of 'showing' something clearly ('show') and the idea of a decisive moment or place ('down') — a showdown is a clear display of confrontation.
