érvényességgel

érvényességgel is the instrumental form of érvényesség, a Hungarian noun that expresses the concept of validity, enforceability, or efficacy. It denotes the state or quality of being in effect, operative, or capable of producing the intended effect. The term is most common in formal or technical language, such as legal texts, policy documents, and scholarly writing, and is less frequent in everyday speech.

In legal and administrative contexts, érvényesség refers to whether a rule, contract, decision, or document is legally in force and binding. In logic and philosophy, érvényesség denotes the validity of an argument or inference, meaning that the conclusion follows from the premises. More broadly, it can describe the effectiveness or real-world impact of a measure, policy, or statement. The nuance between legal validity and logical validity is that the former concerns law and regulation, while the latter concerns reasoning and argument structure.

It appears mainly in formal and technical texts. In everyday language, the noun érvényesség or related adjectives such as érvényes or érvényesség are more common.
