The core idea

The genitive answers кого? чего? (of whom? of what?). Think of it as the "of" case - whenever English uses "of," "from," "'s," or "no/none," Russian reaches for the genitive. Книга брата = "the book of the brother" (brother's book). Нет воды = "there is no water" (absence). Стакан воды = "a glass of water" (quantity).

When to use the genitive case

The genitive has more triggers than any other Russian case. Here are the main ones, roughly ordered by how often you'll hit them.

1. Possession

Russian has no word for "'s." Instead, the possessor goes into the genitive and follows the thing possessed.

2. Absence and negation (нет + genitive)

To say something doesn't exist or isn't present, Russian uses нет + genitive. This replaces "there is no" entirely.

3. After numbers

Russian numbers trigger the genitive in a pattern that trips up every learner:

4. After prepositions

A large group of common prepositions demand the genitive:

5. Partitive genitive (quantities)

When you take some of a larger whole, the "whole" goes into genitive:

6. Comparison

After comparatives, the thing being compared to takes the genitive:

Genitive noun endings

Here's how nouns change in the genitive case. The singular is relatively straightforward; the plural is where the real complexity lives.

GenderNominativeGenitive SingularGenitive Plural
Masculine (hard)стол (table)столастолов
Masculine (soft)учитель (teacher)учителяучителей
Masculine (-ж, -ш, -ч, -щ)нож (knife)ножаножей
Feminine (-а)книга (book)книгикниг
Feminine (-я)неделя (week)неделинедель
Feminine (-ия)станция (station)станциистанций
Neuter (-о)окно (window)окнаокон
Neuter (-е)море (sea)моряморей

The zero ending in genitive plural. This is the pattern that catches learners off guard. Feminine nouns ending in -а simply drop the -а and have no ending at all: книга → книг, рука → рук, сестра → сестёр (with a fleeting vowel). This "zero ending" feels unnatural to English speakers, who expect something to be added, not removed.

Pronoun forms in the genitive

Personal pronouns have their own genitive forms. Note that его, её, их are the same in genitive and accusative - and they gain a н- prefix after prepositions (у него, от неё, для них).

NominativeGenitiveExample
я (I)меняу меня - I have
ты (you)тебяу тебя - you have
он (he)егоу него - he has
она (she)еёу неё - she has
мы (we)насу нас - we have
вы (you pl.)васу вас - you have
они (they)иху них - they have

Example sentences

Real genitive usage across different triggers. Pay attention to the endings.

У меня есть книга брата.
U menya yest' kniga brata.
I have my brother's book.
у + меня (gen. pronoun) for possession; брата (gen. of брат) for "brother's"
В комнате нет стола.
V komnate net stola.
There is no table in the room.
нет + стола (gen. sg. of стол) - absence triggers genitive
Я купил пять книг.
Ya kupil pyat' knig.
I bought five books.
пять + книг (gen. pl. of книга) - numbers 5+ take genitive plural; note the zero ending
Она пришла из магазина без сахара.
Ona prishla iz magazina bez sakhara.
She came from the store without sugar.
из + магазина (gen.) and без + сахара (gen.) - both prepositions require genitive
Дайте мне чашку чая, пожалуйста.
Dayte mne chashku chaya, pozhaluysta.
Give me a cup of tea, please.
чашку (acc. - direct object) + чая (gen. of чай) - partitive genitive for "of tea"

Common pitfalls

These are the mistakes that trip up learners most often with the genitive case.

Cultural note

Russians don't say "I have." There is no direct verb for "to have" in everyday Russian. Instead, possession is expressed with the genitive: У меня есть... (lit. "at me there is..."). The possessor goes into the genitive case after у, and the thing possessed stays in the nominative.

This construction is so central to Russian that it's one of the first structures learners encounter - and it's pure genitive. "У тебя есть собака?" (Do you have a dog?) literally asks "At you is there a dog?" The negative form doubles down on the genitive: "У меня нет собаки" - the possessor (меня) and the thing absent (собаки) are both genitive.

This is why the genitive is sometimes called the first "real" case learners need: you can't even say "I have a book" without it.
