Genitive Case
In a nutshell
- Genitive is the workhorse case: possession ("of"), the entire «у меня́ есть» ("I have") construction, negation, quantities, numbers, and a whole family of common prepositions (из, от, до, без, для, о́коло) all run through it.
- «У меня́ нет» ("I don't have") and «не́ было / не бу́дет» always pair with genitive.
- Numbers are strange: 2, 3, 4 take genitive singular; 5 and up take genitive plural.
- Plural genitive has more irregularity than any other case — including a "zero ending" pattern and fleeting vowels (окно́ → о́кон).
- This lesson is deliberately longer than the others. Budget two study passes, not one.
Genitive earns its reputation as the hardest-working case in Russian. It's the case you'll reach for most often outside of straightforward subject/object sentences, so it's worth slowing down here.
1. Possession — "of"
The core meaning: genitive marks the thing something belongs to, equivalent to English "of X" or "X's."
Э́то кни́га сестры́. — lit. "This book sister-GEN." — "This is my sister's book."
Э́то маши́на бра́та. — lit. "This car brother-GEN." — "This is my brother's car."
Notice there's no word for "of" or an apostrophe-s — the genitive ending on «сестры́» and «бра́та» does that job entirely by itself.
2. Singular genitive endings
| Gender | Nominative | Genitive | Rule |
|---|---|---|---|
| Masc. (consonant) | студе́нт → | студе́нта | add -а |
| Masc. (-ь) | слова́рь → | словаря́ | -ь → -я |
| Masc. (-й) | музе́й → | музе́я | -й → -я |
| Neut. (-о) | окно́ → | окна́ | -о → -а |
| Neut. (-е) | мо́ре → | мо́ря | -е → -я |
| Fem. (-а, hard consonant) | сестра́ → | сестры́ | -а → -ы |
| Fem. (-а, spelling-rule consonant) | кни́га → | кни́ги | -а → -и (г triggers the 7-letter rule) |
| Fem. (-я) | неде́ля → | неде́ли | -я → -и |
| Fem. (-ь) | дверь → | две́ри | -ь → -и |
У меня́ нет словаря́. — lit. "At me not-exist dictionary-GEN." — "I don't have a dictionary."
Fem. -а nouns split the same way plurals did in Gender & Nouns: after a hard consonant you get -ы (сестра́ → сестры́), but after one of the seven spelling-rule letters (г к х ж ш щ ч) you get -и instead (кни́га → кни́ги) — same rule, different case.
3. «У меня́ есть» — the possession construction
Russian has no verb "to have" in everyday use. Instead, possession is expressed as "at me there-exists X," with the possessor in genitive form (after «у») and the thing possessed staying in the nominative.
У меня́ есть соба́ка. — lit. "At me exists dog-NOM." — "I have a dog."
У бра́та есть маши́на. — lit. "At brother-GEN exists car-NOM." — "My brother has a car."
The «у» always takes its object in genitive (that's what "у + genitive" means structurally) — «меня́», «бра́та» are the genitive forms of «я» and «брат». The thing owned («соба́ка», «маши́на») is not genitive — it's the grammatical subject of "exists," so it stays nominative.
Past and future
«Есть» disappears in past/future, replaced by «был/была́/бы́ло/бы́ли» (past) or «бу́дет/бу́дут» (future) — and this verb agrees with the thing possessed, not the possessor.
У меня́ была́ соба́ка. — lit. "At me was-FEM dog-NOM." — "I had a dog." (была́ agrees with feminine соба́ка)
У меня́ бу́дет маши́на. — lit. "At me will-be car-NOM." — "I will have a car."
У нас бы́ли де́ньги. — lit. "At us were money-NOM.PL." — "We had money." (бы́ли agrees with plural де́ньги)
Negation: «у меня́ нет»
To say you don't have something, use нет (present), не́ было (past), or не бу́дет (future) — and critically, the thing not possessed switches to genitive:
У меня́ нет соба́ки. — lit. "At me not-exist dog-GEN." — "I don't have a dog." (соба́ка → соба́ки, genitive)
У меня́ не́ было де́нег. — lit. "At me not was money-GEN." — "I didn't have money."
У меня́ не бу́дет вре́мени. — lit. "At me not will-be time-GEN." — "I won't have time."
This flip is the single most important pattern in this section: affirmative "have" keeps the object in nominative; negative "don't have" pushes the object into genitive. «Нет», «не́ было», «не бу́дет» never change form for gender or number — they stay fixed no matter what's being negated.
4. Quantities and numbers
Genitive shows up any time you're saying "a lot of," "a little of," "how much/many," or a specific count of something.
много / мало / сколько
У меня́ мно́го книг. — lit. "At me much books-GEN.PL." — "I have a lot of books."
Ско́лько вре́мени у тебя́? — lit. "How-much time-GEN at you?" — "How much time do you have?"
У нас ма́ло де́нег. — lit. "At us little money-GEN." — "We have little money."
Numbers: 2-4 vs. 5+
This is a quirk that trips up nearly everyone. Russian numbers govern the case of the noun that follows them, and the rule changes depending on the number:
| Number | Case required | Example |
|---|---|---|
| 1 (оди́н) | nominative singular | одна́ кни́га |
| 2, 3, 4 | genitive singular | две кни́ги, три стола́, четы́ре окна́ |
| 5 and up | genitive plural | пять кни́г, де́сять столо́в |
У меня́ две кни́ги. — lit. "At me two book-GEN.SG." — "I have two books." (кни́ги here is genitive singular, not the nominative plural — they happen to look identical for this noun, which is part of why this rule is confusing; check «стол»/«окно» below where singular and plural clearly differ)
У меня́ три стола́. — lit. "At me three table-GEN.SG." — "I have three tables." (genitive singular «стола́», not plural «столы́»)
У меня́ пять столо́в. — lit. "At me five table-GEN.PL." — "I have five tables." (genitive plural now that we've crossed into 5+)
Compound numbers follow the last digit: 21 behaves like 1, 22–24 behave like 2–4, 25–30 behave like 5+. («два́дцать оди́н стол», «два́дцать два стола́», «два́дцать пять столо́в»)
5. Plural genitive endings
Plural genitive is where Russian gets messy — it's the least predictable case form, and it's worth treating as semi-memorization rather than a clean rule.
| Gender/type | Nominative sg. | Genitive plural | Pattern |
|---|---|---|---|
| Masc. (consonant) | студе́нт | студе́нтов | add -ов |
| Masc. (-ь, -й) | слова́рь / музе́й | словаре́й / музе́ев | add -ей / -ев |
| Neut. (-о) | окно́ | о́кон | zero ending + fleeting vowel |
| Neut. (-е) | мо́ре | море́й | add -ей |
| Fem. (-а) | кни́га | книг | zero ending |
| Fem. (-я) | неде́ля | неде́ль | zero ending + soft sign |
| Fem. (-ь) | дверь | двере́й | add -ей |
The "zero ending" pattern
Many feminine (-а) and neuter (-о) nouns simply drop the ending entirely in genitive plural — no suffix added at all:
кни́га → книг (no ending)
У меня́ мно́го книг. — lit. "At me much books-GEN.PL." — "I have a lot of books." (книг, bare stem, zero ending)
Fleeting vowels
When dropping the ending would leave an awkward consonant cluster at the end of the word, Russian inserts a "fleeting" о or е to make it pronounceable — this vowel appears only in this form and disappears everywhere else.
окно́ → о́кон (not "окн" — the cluster кн is hard to end a word on, so a fleeting о is inserted)
У до́ма пять о́кон. — lit. "At house-GEN five window-GEN.PL." — "The house has five windows."
Irregulars worth memorizing outright
| Nominative sg. | Genitive plural | Meaning |
|---|---|---|
| ме́сто | мест | place(s) — zero ending, no fleeting vowel needed |
| де́ньги (plural-only) | де́нег | money — fleeting е appears |
| челове́к | люде́й* | people (*used after numbers; «люде́й» is the genitive plural of «лю́ди»/челове́к) |
| друг → друзья́ | друзе́й | friends |
У меня́ нет де́нег. — lit. "At me not-exist money-GEN." — "I don't have money." (де́ньги only exists in the plural, and its genitive plural де́нег shows the fleeting е clearly: де́ньги → де́нег)
Здесь мно́го люде́й. — lit. "Here much people-GEN.PL." — "There are a lot of people here."
6. Prepositions that take genitive
A cluster of very common prepositions always take their object in genitive. Worth memorizing as a set:
| Preposition | Meaning | Example |
|---|---|---|
| из | out of, from (origin) | Я из Росси́и. — "I'm from Russia." |
| от | away from, from (a person/source) | Письмо́ от дру́га. — "A letter from a friend." |
| до | until, up to | До за́втра! — "Until tomorrow!" |
| без | without | Ко́фе без са́хара. — "Coffee without sugar." |
| для | for (the benefit of) | Э́то пода́рок для тебя́. — "This is a gift for you." |
| о́коло | near, approximately | О́коло до́ма. — "Near the house." |
Я из Москвы́. — lit. "I from Moscow-GEN." — "I'm from Moscow."
Э́то кни́га для тебя́. — lit. "This book for you-GEN." — "This book is for you."

| Gender | Nominative | Genitive |
|---|---|---|
| Masc. | студе́нт | студе́нта |
| Neut. | окно́ | окна́ |
| Fem. -а | кни́га | кни́ги |
| Fem. -ь | дверь | две́ри |
Summary table — plural
| Gender | Nominative pl. | Genitive pl. |
|---|---|---|
| Masc. | студе́нты | студе́нтов |

| Fem. -а | кни́ги | книг (zero ending) |
| Fem. -ь | две́ри | двере́й |
Practice
- Put «сестра́» into genitive for possession: Э́то маши́на ___. ("This is [my] sister's car.")
- Fill in the affirmative "have": У меня́ ___ (есть/был) кни́га. in the past tense.
- Fill in the negative: У меня́ ___ кни́ги. (I don't have a book — present tense.)
- Put «пять» + «студе́нт» together correctly.
- Put «два» + «окно́» together correctly.
- Give the genitive plural of «кни́га».
- Give the genitive plural of «окно́», and name the phenomenon that produces its form.
- Translate: "I don't have money." (де́ньги)
- Fill in the correct preposition + case: Ко́фе ___ са́хара. (coffee without sugar)
- Translate: "There are a lot of people here." (use «мно́го»)
- Why does «У меня́ есть кни́га» use nominative «кни́га», but «У меня́ нет кни́ги» switches to genitive?
- Give the genitive plural of «друг» (irregular — recall the plural stem from Gender & Nouns).
Answers
- Э́то маши́на сестры́. — genitive marks possession; сестра́ → сестры́. Fem. -а nouns take genitive -ы after hard consonants (р is hard) and -и after the 7 spelling-rule letters (see Gender & Nouns) — «кни́га» → «кни́ги» uses -и because г is one of those letters, while «сестра́» → «сестры́» uses plain -ы because р is not.
- У меня́ была́ кни́га. — past tense "have" uses был/была́/бы́ло agreeing with the possessed noun; кни́га is feminine, so была́.
- У меня́ нет кни́ги. — negation forces genitive; кни́га → кни́ги.
- пять студе́нтов — 5+ triggers genitive plural; студе́нт → студе́нтов.
- два окна́ — 2–4 triggers genitive singular; окно́ → окна́ (genitive sg., not the nominative plural о́кна — note the stress difference: genitive sg. окна́ vs. nominative pl. о́кна).
- книг — zero ending, feminine -а nouns commonly drop the ending entirely in genitive plural.
- о́кон — zero ending plus a fleeting о inserted to avoid the unpronounceable cluster "окн" at the end of a word.
- У меня́ нет де́нег. — lit. "At me not-exist money-GEN." «Де́ньги» is plural-only; its genitive plural де́нег shows a fleeting е.
- Ко́фе без са́хара. — «без» always takes genitive; са́хар → са́хара.
- Здесь мно́го люде́й. — lit. "Here much people-GEN.PL." «Мно́го» always takes a genitive object, and «люде́й» is the genitive plural used for people/челове́к.
- Affirmative «есть» constructions treat the possessed thing as the grammatical subject of "exists," so it stays nominative; negation flips the logic to "of X, none exists," which requires genitive on the thing being negated — this is a fixed pattern, not optional.
- друзе́й — irregular; the plural stem друзья́ (see Gender & Nouns) takes -ей in the genitive plural: друзе́й.
Where this connects
Genitive threads through almost everything ahead: Numbers & Time leans heavily on the 2-4/5+ split above, and you'll see genitive again anywhere negation or quantity comes up. Next: Dative.
