Kijelentés

Kijelentés is the Hungarian term for a statement or assertion. In philosophy, logic and linguistics, it refers to a proposition that can be true or false, typically expressed by a declarative sentence. It stands in contrast to interrogatives (questions) and imperatives (commands).

In logic and formal semantics, a kijelentés carries truth-conditional content. Its truth value is determined by facts about the world or by the interpretation of its terms. In classical logic most kijelentések are bivalent, being either true or false; some logics allow more values or indeterminate truth. The study of kijelentések involves truth conditions, logical consequence, and the relationships between language and reality.

In linguistics, kijelentés corresponds to a declarative (kijelentő mondat) whose primary function is to convey information. Its syntax is typically subject-predicate, and it may be negated or asserted with various intonations. The meaning of a kijelentés depends on both syntax and context, including presuppositions and world knowledge.

Examples include: "A víz forr." (Water boils.) "Ez a könyv kék." (This book is blue.) "A macska az asztalon van." (The cat is on the table.) These sentences express propositions that can be evaluated as true or false under suitable interpretations.
