Personal Pronouns in Russian grammar are an essential part of the language, as they are used to identify and describe relationships between people, objects, or places. They refer to a person or object without naming them. In Russian, personal pronouns are divided into three main categories: first person (referring to the speaker), second person (referring to the listener), and third person (referring to someone or something else). They also change their form depending on the case (nominative, genitive, dative, accusative, instrumental, prepositional). Learning personal pronouns is an essential step toward mastering Russian grammar.
