мой/твой/наш/ваш + Noun
Possessive Pronoun Agreement
Russian possessive pronouns like мой (my) and наш (our) act like adjectives. They change their endings to agree with the noun they belong to, not the person speaking.
How It Works
Possessive pronouns are essential for showing ownership. In Russian, these pronouns are divided into two morphological groups:
1. мой (my) and твой (your, informal): These follow a specific pronominal declension. In the nominative, they are мой (m), моя (f), моё (n), and мои (pl).
2. наш (our) and ваш (your, formal/plural): These have a slightly different stem but follow the same logic. In the nominative, they are наш (m), наша (f), наше (n), and наши (pl).
Key Rules:
- Agreement: The pronoun agrees with the object possessed. If a man says 'my car,' he uses моя машина because 'машина' is feminine.
- Case Declension: These pronouns change their endings in all six cases. For example, in the prepositional case, 'in my house' becomes в моём доме.
- Animacy: In the accusative case, masculine and plural forms follow the animacy rule. If the noun is a person, the pronoun takes the genitive form; if it is an object, it stays like the nominative.
- Omission: Russians often omit possessives if the context is clear (e.g., 'I am washing [my] hands').
Examples (5)
- Это мой папа.
This is my dad.
Word by Word: This [is] my dad.
Even if the speaker is female, 'мой' is used because 'папа' is grammatically masculine.
- Где твоя машина?
Where is your car?
Word by Word: Where [is] your car?
The pronoun 'твоя' is feminine to match the noun 'машина'.
- Мы любим наш город.
We love our city.
Word by Word: We love our city.
Here, 'наш' is in the inanimate accusative, which looks the same as the nominative.
- Я не знаю вашего брата.
I don't know your brother.
Word by Word: I not know your brother.
Because 'брат' is animate and the object of a negative verb, the pronoun 'ваш' changes to the genitive/animate accusative form 'вашего'.
- В нашем классе пять студентов.
There are five students in our class.
Word by Word: In our class five students.
The pronoun 'наш' takes the prepositional ending '-ем' to match 'классе'.
Common Mistakes
Matching the pronoun to the speaker's gender instead of the noun's gender.
Моя папа врач.Мой папа врач.Even if a woman is speaking, 'папа' is masculine, so the pronoun must be 'мой'.
Declining the 3rd-person possessives (his, her, their).
Я видел егого друга.Я видел его друга.Unlike мой/твой/наш/ваш, the pronouns его, её, and их are invariable and never change their endings.
Forgetting to change the pronoun case in prepositional phrases.
Я живу в мой дом.Я живу в моём доме.When a noun changes case (here, to prepositional), the possessive pronoun must change with it.
