In Russian grammar, demonstrative pronouns are used to indicate specific objects or people in a sentence. These pronouns help provide clarity and context by pointing out which object or person is being referred to. In Russian, there are three main demonstrative pronouns: этот (this), тот (that), and который (which one). These pronouns change their form depending on the gender, number, and case of the noun they modify. Learning and practicing how to use demonstrative pronouns in Russian will help you better communicate in both written and spoken language.
