Kripke semantics interprets logical formulas at worlds related by an accessibility relation or an information order. Modal logics use accessibility to interpret modal operators; intuitionistic logics use persistent valuations and quantify over stronger worlds for implication.

Kripke semantics is a formal framework used in modal logic to evaluate the truth of modal propositions, which include concepts like necessity and possibility. Developed by the philosopher Saul Kripke in the 1960s, this approach provides a way of interpreting modal formulas through the use of relational structures called "frames." In Kripke semantics, the fundamental components are: 1. **Worlds**: These represent different possible states of affairs or scenarios.
