Tarski's theorem on truth

Tarski's theorem on truth states that the concept of "truth" can be formally defined for a language in a precise way. Specifically, it asserts that a sentence is true if it accurately describes a state of affairs in the world. For example, the statement "snow is white" is true if, in reality, snow is indeed white. Tarski showed that we can create a consistent and rigorous framework for understanding truth in mathematical and logical contexts, distinguishing between different languages and their meanings, while highlighting the complexities involved in defining truth universally.
