What are the rules for Polish declensions?

Polish declensions involve changing the endings of nouns, adjectives, and pronouns to show their grammatical role in a sentence. There are seven cases in Polish: nominative, genitive, dative, accusative, instrumental, locative, and vocative. Each case has its own set of rules for forming the correct endings based on the gender, number, and animacy of the Word. Learning these rules is essential for mastering Polish grammar.
