Érvényesség

**érvényesség** refers to the quality or state of being valid, effective, or applicable within a given context. The term is commonly used in legal, philosophical, and linguistic discussions to describe the legitimacy or force of a rule, principle, or statement. In legal contexts, *érvényesség* pertains to the binding authority of a law, regulation, or judicial decision, meaning it is recognized as legally enforceable and applicable until formally repealed or superseded.

In philosophy and logic, the concept examines the validity of arguments, theories, or claims based on their adherence to established reasoning standards. A statement or principle is considered *érvényes* if it aligns with logical consistency and empirical evidence, ensuring its credibility within a particular framework. This idea is closely tied to the broader notion of truth and justification, where *érvényesség* serves as a measure of whether a proposition holds weight in a given discourse.

Linguistically, the term can describe the correctness or appropriateness of language use within specific rules, such as grammar or semantic conventions. Here, *érvényesség* ensures that expressions are meaningful and contextually fitting, avoiding ambiguity or misinterpretation.

The concept is also relevant in social and cultural contexts, where norms, traditions, or customs may be evaluated for their continued relevance or effectiveness. In such cases, *érvényesség* assesses whether practices remain socially or functionally valid over time, often influencing their preservation or adaptation.

While closely related to terms like *hitelesség* (trustworthiness) or *hatályosság* (effectiveness), *érvényesség* specifically emphasizes the inherent validity or authority of something within its defined scope, distinguishing it from mere practical utility or subjective belief.
