bliszych
Bliszych is the genitive plural form of the Polish adjective bliski, meaning near or close. It is used when the noun it modifies is in the genitive plural, for example in phrases such as potrzeby bliskich (the needs of the close ones) or kontakt z bliskich członków rodziny (contact with family members). The base adjective has the forms bliższy (masculine singular), bliższa (feminine singular), bliższe (neuter singular), and plural forms such as bliżsi (masculine), bliższe (neuter), with the genitive plural being bliższych. In everyday writing, the form bliższych is standard; the non-diacritic variant bliszych may appear in texts where diacritics are omitted, but it is not the preferred spelling in proper Polish orthography.
