unchallenged
UK: ʌnˈtʃælɪndʒd | US: ʌnˈtʃælɪndʒd
adj. not disputed or questioned; accepted without opposition
adj. not confronted with a challenge or test
The word "unchallenged" combines the negative prefix "un-" (from Old English "un-," meaning "not") with the verb "challenge" (from Old French "chalongier," meaning "to accuse or dispute," derived from Latin "calumniari," meaning "to accuse falsely"). The suffix "-ed" turns the verb into an adjective, indicating a state of being. Historically, "challenge" evolved from legal accusations to broader confrontations, making "unchallenged" imply something accepted without opposition or scrutiny.
