základních

Základních is the genitive plural form of the Czech adjective základní, meaning basic or fundamental. In Czech, adjectives agree with the noun they modify in gender, number and case, and the ending -ních marks the genitive plural. This form is common in formal and technical language when describing multiple items in a genitive construction.

The word stems from záklád, meaning base or foundation, and is used to denote essential, core, or fundamental aspects of a subject. As a grammatical form, základení (the base form základní) appears in phrases where the noun it modifies is in genitive plural, such as základních pravidel, základních údajů or základních položek. It functions to qualify the noun by indicating that what is being described is part of the base or essential set.

Usage and meaning: základních conveys the idea of core, essential, or baseline elements within a larger whole. It is applied across domains including education, law, science, and data reporting. For example, a list of základních pravidel means a list of basic rules, and a summary of základních údajů refers to essential data.

Notes: in English, záklonní equivalents are basic or fundamental. The form základení appears in genitive plural contexts, and speakers choose it to express the relationship between a noun and its essential components.
