Marble bust of Aristotle with a beard and draped robe, showing detailed facial features and wavy hair, set against a dark background. — Truth Detail of a Roman copy (2nd century bce) of a Greek alabaster portrait bust of Aristotle (c. 325 bce); in the collection of the Museo Nazionale Romano, Rome.

In the context of Alfred Tarski’s work on truth conditions, a T-sentence defines the truth of a statement by linking an object language sentence to its translation in a metalanguage.1

For the German statement “Schnee ist weiss,” the T-sentence is: “Schnee ist weiss” is true if and only if snow is white.1

This structure functions as follows:
* Object Language: The German sentence “Schnee ist weiss” is the subject being analyzed.1
* Metalanguage: The English phrase “snow is white” serves as the translation used to construct the theory.1
* Truth Condition: By stating that the sentence is true if and only if the condition (snow being white) is met, Tarski provides a partial definition of truth without using the term “true” within the object language itself.1

Tarski argued that the sum of such T-sentences for every sentence in a language provides a complete definition of truth.1
