polskojzycznych
Polskojzycznych is not a standard Polish word. It is a transliteration variant of the Polish adjective polskojęzycznych (a form used in phrases referring to Polish-speaking groups or Polish-language material). In proper Polish, the base adjective is polskojęzyczny (singular), polskojęzyczni (masculine personal plural), and polskojęzyczne (neuter plural), with polskojęzycznych serving as the genitive plural form in phrases such as polskojęzycznych mediów or polskojęzycznych użytkowników. The meaning conveyed is “Polish-speaking” or “Polish-language” in reference to people, texts, media, or communities.
Etymology and meaning: The term combines polsko- (Polish) with języczny (related to language, from język, language).
Usage notes: In Polish, correct usage depends on grammatical case and number. For example, “języczny” would agree
