validni

Validni is a non-English term used in several Slavic languages as an adjective meaning valid or legitimate. In standard orthography, it appears as validní in Czech and validný in Slovak; in texts without diacritics it is written as validni. The form is derived from Latin validus via Proto-Slavic and shares a common semantic core with the English word valid and the broader notion of validity.

In Czech and Slovak, validní/validný describes documents, statements, or data that meet required conditions. In legal, administrative, and technical language, phrases such as “platný doklad” (valid document) or “validita” (validity) are common; validní tends to convey compliance with specified rules or standards. The term is frequently used in contexts where something must be current, authentic, or acceptable under rules or norms.

In computing and data processing, adjectives like “validní vstup” (valid input) appear in discussions of input validation and data quality. Related nouns include “validace” (validation) and concepts tied to correctness and consistency of information.

Cross-linguistic note: In other South Slavic languages such as Croatian, Serbian, and Bosnian, everyday equivalents are “valjan/važeći” rather than a direct loanword, though non-diacritic texts or technical documents may still show the form “validni.” This reflects broader patterns of orthography and register across languages that share similar roots.
