Possessive Pronouns Possessive pronouns of the 1st and 2nd persons (мой, твой, наш and ваш) and the interrogative pronoun чей change for gender in the singular and have one form common to all genders in the plural (чьи? — мои, твои, наши, ваши). —Чей это карандаш? — Это мой карандаш. — Это твой карандаш. — Это наш карандаш. — Это ваш карандаш. ( –Whose pencil is it? –It is my pencil. –It is your pencil. –It is our pencil. –It is your pencil); — Чья это книга? — Это моя книга. — Это твоя книга. — Это наша книга. — Это ваша книга. (–Whose book is it? –It is my book. –It is your book. –It is our book. –It is your book) As is seen from the preceding examples, these possessive pronouns invariably agree in gender with the noun they qualify. The Form of the Possessive Pronouns in the Nominative. Possessive pronouns of the 3rd person (его, её and их) don't change for number and gender, the choice of the appropriate pronoun depending on the possessor of the object being qualified. If the possessor is a man pronoun его is used, if the possessor is a woman её is used, if the object being qualified belongs to a number of possessors их is used. For instance, the word книга can be qualified either by the pronoun его, or её, or их depending on who it belongs to, the gender and number of the object qualified not influencing the form of the pronoun (его книга, его журнал).
