True is a term used to describe the quality of being in accord with fact, reality, or how things actually are, when applied to statements, beliefs, or judgments. In logic and mathematics, truth is typically a property of declarative sentences: a statement is true if it accurately reflects the way the world is, and false otherwise. The word has Old English roots, with forms such as treowe meaning faithful or trustworthy, connected to the broader concept of veracity.

Philosophical theories of truth seek to explain what makes statements true. The correspondence theory holds that

In formal settings, truth is given a precise role. In classical logic, truth values are typically true

Truth can be context-dependent and revisable; it is reinforced by evidence, observation, and reproducibility in science,
