KK: /ʌndɪˈspjuːtɪd/
Something that is accepted by everyone and not questioned or challenged.
He is the undisputed champion of the tournament.
Undisputed → It is formed from "un-" (meaning not) and "disputed" (from Latin "disputare", meaning to argue or debate). The word "undisputed" means not subject to argument or debate, indicating something that is accepted without question.
Think of something that is 'not' ('un-') 'argued about' ('disputare') — that's why undisputed means something everyone agrees on.
