POLISH LANGUAGE - Nouns and adjectives

Polish is highly inflected and retains the Old Slavic case system with seven cases for nouns, pronouns, and adjectives: nominative, genitive, dative, accusative, instrumental, locative and vocative. There are two numbers, singular and plural.
The Polish gender system is complex, due to its combination of three categories: gender (masculine, feminine, neuter), personhood (personal versus non-personal) and animacy (animate versus inanimate). Personhood and animacy are relevant within the masculine gender but do not affect the feminine or neuter genders. The resulting system can be presented as comprising five gender classes: personal masculine, animate (non-personal) masculine, inanimate masculine, feminine, and neuter. These classes can be identified based on declension patterns, adjective-noun agreement, and pronoun-antecedent agreement.
