Truth-conditional semantics

Truth-conditional semantics is a theory in the philosophy of language and linguistics that explains the meaning of sentences in terms of the conditions under which those sentences would be true. In other words, a sentence's meaning can be understood by identifying the specific situations or states of affairs in the world that would make that sentence true. The central idea of truth-conditional semantics is that knowing the meaning of a sentence includes knowing what the world would have to be like for that sentence to be true.
