Possessive Pronouns in Russian

In Brief

Russian possessives identify an owner: мой дом (“my house”), твоя сестра (“your sister”), and наши друзья (“our friends”). Мой, твой, наш, ваш change to match the gender, number, and case of the thing owned; его, её, их never change. Russian also uses свой for something belonging to the subject of the sentence.

Overview

A possessive pronoun is a word such as “my,” “your,” or “their” that shows a relationship of ownership or association. A noun is a naming word such as “house,” “sister,” or “idea.” In Russian, possessives normally come before their noun: моя книга (“my book”), наш город (“our city”). They are essential from A1 onward when talking about family, belongings, work, and home.

The first important difference from English is agreement: a changing word takes a form that matches another word. Russian мой changes according to the thing possessed, not according to the owner. A male speaker and a female speaker both say мой телефон, because телефон is masculine, and both say моя машина, because машина is feminine.

For a beginner, start with the nominative case—the basic dictionary form, used especially for the subject (the person or thing the sentence is about) and after это in identification sentences. Later, the same possessives also change for case, meaning their endings reflect the noun’s role in the sentence. The major exceptions are его, её, and их, which remain exactly the same everywhere.

How It Works

The basic forms

Russian has no single form corresponding to English “your.” It distinguishes informal singular твой from ваш, used for more than one person and also for formal address to one person.

Owner	Masculine	Feminine	Neuter	Plural	Meaning
я	мой	моя	моё	мои	my
ты	твой	твоя	твоё	твои	your, informal singular
он	его	его	его	его	his
она	её	её	её	её	her
мы	наш	наша	наше	наши	our
вы / Вы	ваш	ваша	ваше	ваши	your, plural or formal
они	их	их	их	их	their

The letter ё is often printed as е, so you may see мое and твое. They are still pronounced with ё: моё, твоё. Writing ё is especially helpful for learners.

Match the thing owned

Choose the form from the noun’s gender or number:

• masculine: мой брат, твой паспорт, наш урок
• feminine: моя сестра, твоя работа, наша комната
• neuter: моё имя, твоё письмо, наше место
• plural: мои друзья, твои ключи, наши дети

Gender is a grammatical category, not necessarily biological sex. For example, книга (“book”) is feminine and письмо (“letter”) is neuter. If noun gender is unfamiliar, review it before memorizing all the possessive endings.

Three possessives never agree

Его (“his”), её (“her”), and их (“their”) do not change for gender, number, or case:

Form	With different nouns
его	его брат, его сестра, его письмо, его друзья
её	её брат, её сестра, её письмо, её друзья
их	их брат, их сестра, их письмо, их друзья

Do not add adjective endings to these words. Forms such as еговая or ихние are not standard neutral Russian. You may hear nonstandard ихний in colloquial or regional speech, but learners should use standard их.

Agreement across cases

A case is a set of endings that shows what a noun does in a sentence—for example, whether it is the subject, direct object, recipient, or location. Мой, твой, свой follow the same pattern. Наш and ваш follow a regular hard-adjective pattern.

Here is the singular pattern for мой:

Case	Masculine	Feminine	Neuter	Typical idea
Nominative	мой	моя	моё	basic form / subject
Accusative	мой / моего	мою	моё	direct object
Genitive	моего	моей	моего	of, from, absence
Dative	моему	моей	моему	to or for
Instrumental	моим	моей / моею	моим	with, by
Prepositional	моём	моей	моём	about, in, at

In the masculine accusative, use мой with an inanimate noun (вижу мой дом, “I see my house”) but моего with an animate noun—a person or animal (вижу моего брата, “I see my brother”). In natural Russian, the reflexive свой is often preferred in these examples when the owner is also the subject; that distinction is explained below.

The plural forms are:

Case	мой	наш
Nominative	мои	наши
Accusative, inanimate	мои	наши
Accusative, animate	моих	наших
Genitive	моих	наших
Dative	моим	нашим
Instrumental	моими	нашими
Prepositional	моих	наших

Substitute твой or свой into the мой pattern, and ваш into the наш pattern. Meanwhile, его, её, and их remain unchanged even when the noun changes case: нет его книги, говорю о её работе, встречаю их друзей.

Possessives can stand without a noun

When the missing noun is clear, a possessive can be used by itself:

• Чья это сумка? — Моя. (“Whose bag is this? — Mine.”)
• Этот телефон ваш? (“Is this phone yours?”)
• Наш дом большой, а их маленький. (“Our house is big, but theirs is small.”)

The form still agrees with the understood noun. Сумка is feminine, so the answer is моя, not мой. Russian does not have a separate set like English “my/mine” or “your/yours”; context allows the same Russian forms to do both jobs.

Asking “whose?”

The question word чей follows the same basic agreement pattern:

Masculine	Feminine	Neuter	Plural
чей?	чья?	чьё?	чьи?

Ask Чей это паспорт?, Чья это куртка?, Чьё это место?, or Чьи это вещи? The answer matches the noun too: мой, моя, моё, мои.

Common Mistakes

Matching the owner instead of the possession

• Wrong: моя брат
• Right: мой брат
• Why: The owner may be female, but брат is masculine. The possessive agrees with брат, the person possessed or related to the owner.

Leaving a changing possessive in its dictionary form

• Wrong: мой книга, мой друзья
• Right: моя книга, мои друзья
• Why: мой changes for feminine and plural nouns. Learn each noun together with its gender.

Changing его, её, or их

• Wrong: ея книга, ихняя машина
• Right: её книга, их машина
• Why: Standard его, её, их are invariable. Case and agreement affect the following noun, not the possessive.

Using твой in formal or plural address

• Wrong: Где твой паспорт? (to a customer or to several people)
• Right: Где ваш паспорт? (formal singular) / Где ваши паспорта? (plural)
• Why: твой belongs with informal singular ты. Ваш belongs with plural вы and formal Вы.

Forgetting case agreement

• Wrong: Я говорю о мой работе.
• Right: Я говорю о моей работе.
• Why: After о meaning “about,” the noun is in the prepositional case, so both the possessive and noun change.

Using его or её when the subject owns the item

• Awkward or different: Анна любит её работу.
• Natural for “her own”: Анна любит свою работу.
• Why: свою points back to the subject, Anna. Её normally suggests another woman’s job or creates ambiguity.

Usage Notes

Твой and ваш express social relationships

Use твой with someone you address as ты: a friend, child, close colleague, or family member. Use ваш with people addressed as вы: several people, or one person in a formal or respectful relationship. Social practice varies by setting, age, and workplace, so follow the form of address used by Russian speakers around you.

In ordinary text, lowercase вы, ваш is common even for polite singular address. Capitalized Вы, Ваш may be used when writing directly and respectfully to one person, especially in formal correspondence, questionnaires, or customer communication. It is not required in every polite sentence and is not used merely because the referent is important.

Possession is broader than ownership

As in English, these forms can show family, association, authorship, or experience rather than legal ownership: моя сестра (“my sister”), наш учитель (“our teacher”), его идея (“his idea”), их поезд (“their train”). Russian may also use у + genitive + есть to say that someone has something: У меня есть машина (“I have a car”). That construction states possession; моя машина identifies which car is mine.

Word order and emphasis

The neutral order is possessive plus noun: моя книга. Moving the possessive after the noun can add contrast, emotion, or a literary tone: Это книга моя, не твоя (“This book is mine, not yours”). Beginners should use the neutral order unless there is a clear contrast.

Beyond the Basics: Свой and Other Subtleties

You do not need to master every detail at A1, but свой is frequent enough that you should recognize it early. It means “one’s own” and refers back to the subject—the person or thing performing the action or being described.

Russian	English	What the possessive refers to
Иван читает свою книгу.	Ivan is reading his own book.	свою = Ivan’s
Иван читает его книгу.	Ivan is reading his book.	его normally = another man’s
Анна показала нам свою комнату.	Anna showed us her room.	свою = Anna’s
Анна показала нам её комнату.	Anna showed us her room.	её normally = another woman’s
Мы любим свой город.	We love our city.	свой = the subject “we”

Like мой and твой, свой agrees with the possessed noun: свой дом, своя квартира, своё место, свои вещи. It can refer to any grammatical person: my own, your own, his own, her own, our own, or their own. Its owner comes from the subject, not from the ending.

With first- and second-person subjects, мой/наш/твой/ваш may still be possible, especially for contrast: Я взял мою сумку, а не твою (“I took my bag, not yours”). Without contrast, Я взял свою сумку is usually the neutral choice. With a third-person subject, the contrast is particularly useful because свой and его/её/их can identify different owners.

Be careful when the owner is not the sentence’s grammatical subject. In Мама попросила Антона взять свою куртку (“Mom asked Anton to take [someone’s] own jacket”), свою can be structurally ambiguous in some contexts: it may be interpreted through the main subject or through the understood doer of the infinitive. Clear writing often names the owner or rewrites the sentence.

A few possessive adjectives are formed from names or family words, such as мамин (“Mom’s”), папин (“Dad’s”), or Сашин (“Sasha’s”). They also agree: мамина книга, папино кресло, Сашины друзья. These are related to possession but are not members of the basic pronoun set.

Finally, его, её, их can look identical to ordinary personal-pronoun forms. Compare Я вижу его (“I see him”), where его stands alone as the object, and Я вижу его дом (“I see his house”), where его modifies дом. The following noun and the meaning of the whole sentence reveal the function.

Practice Tips

1. Build four-form sets. Take five common nouns and combine them with one possessive: мой телефон, моя книга, моё окно, мои ключи. Say the noun’s gender or number aloud as you choose the ending.
2. Add cases gradually. Once the basic forms are automatic, practice one frame at a time: нет моей книги, к моему дому, о моих друзьях. Change both the possessive and the noun together.
3. Track the owner with arrows. In sentences with свой, mark the subject and draw an arrow from свой back to it. Contrast pairs such as Анна взяла свою сумку / Анна взяла её сумку make the ownership difference memorable.
