The word "unambiguous" combines the negative prefix "un-" (from Old English "un-," meaning "not") with the root "ambigu" (from Latin "ambiguus," meaning "doubtful" or "uncertain") and the adjective-forming suffix "-ous" (from Latin "-osus"). The root "ambigu" itself derives from Latin "ambigere," meaning "to wander around" or "to be uncertain," reflecting the idea of vagueness. Over time, "unambiguous" evolved to signify clarity by negating the inherent uncertainty in "ambiguous."
