tautosság
Tautóság is a term used in linguistics and philosophy to describe a statement or proposition that is true by necessity or by virtue of its logical structure. A tautology is inherently true and does not depend on empirical evidence or the state of the world for its truth value. For example, the statement "All bachelors are unmarried men" is a tautology because the definition of a bachelor is an unmarried man. The truth of this statement is contained within the meanings of the words themselves.
In logic, tautologies are often represented by symbolic formulas that are true for all possible truth-value
The term "tautology" can also be used more broadly to refer to any statement that is trivially
