What is a basic definition of truth? Truth means the actual state of a matter, an adherence to reality, or an indisputable fact. Truth has several other senses as a noun. The truth refers to the version of reality that we exist in. Putting it more simply, if you are “telling the truth,” you are describing the world as it actually is and not making things up or telling lies.
See truism.
First recorded before 900; Middle English treuthe, Old English trēowth (cognate with Old Norse tryggth “faith”); see true, -th 1
Truth is something that squares with reality. When you are sworn in to give testimony in a U.S. court of law, you promise to "tell the truth, the whole truth, and nothing but the truth." When you're cutting to the heart of something, you might start a statement with, "The truth of the matter is..." or "To tell the truth..." When you hear these introductory phrases containing truth, reality is supposed to follow. The American comedian Stephen Colbert coined the term truthiness as a satirical poke at politicians and pundits whose claims often have no basis in reality. Truthiness is what you wish were truth — unconstrained by fact or logic.
