kategorií

Kategorií is the genitive plural form of the noun meaning category in Czech and Slovak. It is used to express “of categories” or to indicate quantity in phrases that count or describe categories. In these languages the respective base words are kategórie in Slovak (singular kategória) and kategorie in Czech (singular kategorie); their genitive plurals are kategórií in Slovak and kategorií in Czech. Thus, you encounter kategorií in sentences that talk about parts of a whole, such as “počet kategorií” in Czech or “počet kategórií” in Slovak, both meaning “the number of categories.”

The form reflects standard Slavic noun inflection, where the genitive plural is used after numerals and in possessive or descriptive phrases. For example, Czech: “Počet kategorií byl zjištěn.” Slovak: “Počet kategórií bol zistený.” Beyond grammar, the word connects to broader concepts of classification and taxonomy, appearing in discussions of data organization, information architecture, libraries, and content management, where categories are a fundamental way to group items.

Etymologically, the term derives from the notion of category or class and has circulations in many European languages through Latin kategoria and its descendants. In practice, kategorií serves as a grammatical tool rather than a standalone semantic unit, and its usage varies with spelling based on the language (Czech vs. Slovak) and the presence of diacritics.
