klúové

Klíové is a form associated with the Czech adjective klíčový, which carries the sense of key, crucial, or central. In standard Czech usage, the neuter singular form of this adjective is klíčové, used with neuter nouns such as slovo (word) or jiný neuter noun, to denote something essential or central.

In practice, klíčové appears in common phrases that describe important elements or features, for example klíčové slovo (keyword) or klíčové faktory (key factors). The adjective agrees with the gender and number of the noun it modifies, so the exact ending changes with the noun’s gender and count. The form klíové, while sometimes seen in informal lettering or typographical variants, is not the standard neuter singular in contemporary Czech orthography.

Etymologically, klíčový derives from the noun klíč, meaning key. The pair expresses a relationship of importance or centrality, rather than a physical key. In academic, media, and technical writing, the concept of something being “key” is conveyed with this adjective, often in compound terms that name essential components, principles, or factors.
