jakich

Jakich is a grammatical form in Polish that serves as the genitive plural (and the accusative plural masculine personal) of the interrogative and relative determiner "jaki," meaning "which" or "what kind of." It is not a standalone word with a fixed meaning, but a case-inflected form used to introduce or modify nouns in phrases that ask about or specify kinds or types.

In practice, jakich appears most prominently in compounds and constructions that express indefiniteness or quantity. One common family is formed with the intensifier kolwiek, as in jakichkolwiek, which translates to "any" or "whatever kind of." For example, "jakichkolwiek informacji" means "any information" or "whatever information." Another frequent use is in phrases where the noun is in the genitive plural, such as "jakich pytań" meaning "which questions" or "what questions" in a dependent clause, e.g., "Nie wiem, jakich pytań mogę się spodziewać" (I don’t know what questions I may expect).

Jakich also appears in other contexts that require a genitive plural determiner, typically following verbs or adjectives that govern a genitive object or complement. It shares its root with the base form "jaki," and the form paradigm continues to appear in both formal and colloquial Polish, especially in indirect questions and relative clauses.

Etymologically, jakich derives from the Slavic interrogative pronoun/adjective series linked to "jaki," which in turn traces back to Proto-Slavic roots for asking about kind or type. Related forms include jaki (nominative), jakie/jaka (neutral/feminine), and other inflected variants used across cases and numbers.
