untrue
UK: ʌnˈtruː | US: ʌnˈtruː
adj. not in accordance with fact or reality; false
adj. not faithful or loyal
The word "untrue" combines the Old English prefix "un-" (meaning "not") with the adjective "true," which derives from the Old English "trēowe" (meaning "faithful, trustworthy"). Over time, "true" evolved to signify conformity to fact or reality, while "un-" consistently negates its root. The pairing reflects a straightforward logical opposition, where "untrue" directly inverts the qualities of truthfulness or accuracy.

The witness gave an untrue account of the incident.
