the state or quality of being true or factual
Truth is what is or what was: the actualité. Usually it is revealed as a conclusion, reliably evidenced by observation or documentation, or as an inference from primary facts. Historical truth is more elusive, since history, as Richard Nixon pointed out, depends on who writes it. A jury delivers a ‘true’ verdict, but only in respect of the evidence presented to it, which may lead to false conclusions — Geoffrey Robertson
something that is true or is believed to be true, as distinct from a lie
