Premenným

Premenným is the instrumental singular masculine form of the Slovak adjective premenný, which means variable. It is a grammatical form used when an adjective describing a masculine noun is in the instrumental case, a situation common in technical or formal Slovak writing. The form signals that a property or characteristic is variable in nature.

In mathematical, statistical, and computing texts, premenným appears in phrases describing how something is performed or characterized with respect to a variable. Examples include premenným spôsobom (in a variable manner), premenným faktorom (a variable factor), or premenným prvkom kódu (a variable element of code). The feminine singular instrumental form is premennou, and the plural instrumental form is premennými.

The term is etymologically linked to the noun premenná (variable) and is used as an adjectival form to modify masculine nouns in instrumental construction. It exemplifies Slovak agreement rules, where adjectives change their endings to match gender, number, and case of the nouns they describe.
