základními

Základními is the instrumental plural form of the Czech adjective základní, meaning basic or fundamental. It is used to modify nouns in the instrumental case, typically after the preposition s to indicate “with basic” or “using basic” concepts, information, rules, and similar items.

In Czech, adjectives agree with the noun in gender, number, and case. For the plural instrumental, adjectives ending in -ní take the form -ními. Therefore základní becomes základními in instrumental plural contexts, for example s základními pravidly (with basic rules) or s základními informacemi (with basic information).

Usage notes: The form Základními is not a noun by itself; it functions as an adjective in the instrumental plural and occurs in phrases describing items in that case. It is common in technical, educational, and formal language, as well as in explanations of procedures or methods.

Etymology and meaning: The adjective zákl adní is derived from základ, meaning base or foundation. In translation, základní corresponds to basic, fundamental, or essential, depending on the context.
