Tarski's definitions

Tarski’s definitions, especially in logic and mathematics, provide precise ways to specify what it means for statements and concepts to be true. He introduced formal methods to define truth using a systematic framework, ensuring that the meaning of statements is clear and unambiguous within a language. For example, he established rules that determine when a statement about a mathematical structure is considered true, based on its components and how they relate to the structure. His work helps ensure that discussions about mathematical or logical concepts are consistent, rigorous, and free from ambiguity.
