IPA: /ˈʃʌtaʊt/
KK: /ˈʃʌtaʊt/
A game or match where one team or player does not score any points.
The final score was 3-0, resulting in a shutout for the winning team.
Shutout is formed from "shut" (from Old English "scyttan", meaning to close or block) and "out" (meaning away from the inside). The word "shutout" refers to a situation where one team prevents the other from scoring, effectively closing them out of the game.
Think of 'closing' ('shut') someone 'away' ('out') — that's why a shutout means keeping the other team from scoring.
