idejí

Idejí is a grammatical form of the Czech noun idea. It is the genitive plural form, used when the noun is governed by a preposition or another word that requires the genitive case, or in constructions that express quantity. The form idejí appears in written Czech, especially in formal or literary contexts, and in historical texts. In everyday speech speakers may use alternative words such as nápady, but idejí remains common in phrases that require the genitive plural.

Etymology and classification

Idejí derives from the noun idea, a feminine noun in Czech. The word idea itself traces through Slavic and Romance-era borrowings from Latin idea, which in turn has Greek roots. The genitive plural ending idejí reflects Czech inflection patterns for feminine nouns ending in -a that adopt the -í ending in certain oblique cases.

Usage

Idejí is used after numerals and quantifiers that take genitive, or after prepositions that govern the genitive. Examples in standard Czech include phrases like mnoho idejí (many ideas) or bez idejí (without ideas). It may also appear in formal lists or philosophical writing where a more precise grammatical structure is preferred.
