Truth is most often used to mean being in accord with fact or reality, or fidelity to an original or standard. Truth is also sometimes defined in modern contexts as an idea of "truth to self", or authenticity.
Truth is usually held to be opposite to falsehood, which, correspondingly, can also suggest a logical, factual, or ethical meaning.
The concept of truth is discussed and debated in several contexts, including philosophy, art, theology, and science. Most human activities depend upon the concept, where its nature as a concept is assumed rather than being a subject of discussion; these include most of the sciences, law, journalism, and everyday life. Some philosophers view the concept of truth as basic, and unable to be explained in any terms that are more easily understood than the concept of truth itself.
To some, truth is viewed as the correspondence of language or thought to an independent reality, in what is sometimes called the correspondence theory of truth.
Truth is often as seen in the eye of the beholder.
As was said by one far more eloquent than I; "I have never been untruthful to you however, which version of the Truth would you care to hear?"
