klúovým

Klíčový is a Czech adjective meaning key, crucial, or pivotal. The form klíčovým represents the instrumental singular masculine or neuter form, used to describe a noun in instrumental position within noun phrases or predicative clauses. For example, in the phrase Klíčovým faktorem úspěchu je týmová spolupráce, the head noun faktorem is instrumental, and the sentence means “A key factor of success is team collaboration.” The root meaning derives from klíč, “key,” extended metaphorically to denote central importance.

Etymology and usage. The word combines klíč (key) with the suffix -ový to form an adjective describing something central or essential. In Czech, klíčový is widely used in formal and analytical language across business, politics, science, and media. The instrumental form klíčovým appears when the associated noun is in the instrumental case, as in Klíčovým bodem jednání byl návrh na rozpočet (The proposal was a key point of the meeting).

Grammar notes. In feminine form, the instrumental is klíčovou, and in plural it is klíčovými. The standard instrumental form is klíčovým; klíovým without č would be considered a misspelling in correct Czech orthography. Examples help illustrate usage: Klíčovým prvkem systému je bezpečnostní protokol (Key element of the system is the security protocol); Klíčovým faktorem úspěchu je týmová spolupráce.
