Possessive Pronouns in Ukrainian grammar are used to show ownership or possession. They are similar to English possessive pronouns (my, your, his, her, its, our, their) and indicate the relationship between the noun and the person who owns or possesses it. In Ukrainian, possessive pronouns need to agree in gender, number, and case with the noun they describe. There are three genders (masculine, feminine, and neuter), two numbers (singular and plural), and seven cases (nominative, genitive, dative, accusative, instrumental, locative, and vocative). This makes mastering possessive pronouns essential for expressing possession in Ukrainian.
