In Russian, every word that says how much or how many drags the counted noun into the genitive. This is not optional and not occasional — мно́го ("a lot"), ма́ло ("few/little"), немно́го ("a bit"), не́сколько ("several"), ско́лько ("how much/many"), сто́лько ("so much/many"), and the comparatives бо́льше ("more") and ме́ньше ("less/fewer") all govern the genitive. The one fork you must learn is singular vs plural: things you can count go genitive plural (мно́го книг), while mass and abstract nouns go genitive singular (мно́го воды́). English hides this split inside the words much and many; Russian forces you to decide every time.
The rule: quantity word + genitive
The quantity word leads; the noun follows in the genitive. Compare with English, which leaves the noun untouched:
| Quantity word | Meaning | Example |
|---|---|---|
| мно́го | a lot, many, much | мно́го книг (a lot of books) |
| ма́ло | few, little, not much | ма́ло вре́мени (little time) |
| немно́го | a little, a bit | немно́го са́хара (a bit of sugar) |
| не́сколько | several, a few | не́сколько домо́в (several houses) |
| ско́лько | how much / how many | ско́лько люде́й? (how many people?) |
| сто́лько | so much / so many | сто́лько рабо́ты (so much work) |
| бо́льше / ме́ньше | more / less, fewer | бо́льше де́нег (more money) |
У меня́ до́ма мно́го книг.
I have a lot of books at home. (кни́ги → genitive plural книг — countable)
Ско́лько люде́й бы́ло на конце́рте?
How many people were at the concert? (genitive plural люде́й after ско́лько)
У нас о́чень ма́ло вре́мени.
We have very little time. (вре́мя → genitive singular вре́мени — mass/abstract)
The count/mass split: plural vs singular
Now the one decision. Ask: can I count this noun?
- Countable (books, houses, people) → genitive plural: мно́го книг, не́сколько домо́в, ско́лько люде́й.
- Mass or abstract (water, time, sugar, happiness) → genitive singular: мно́го воды́, ма́ло вре́мени, немно́го са́хара, мно́го сча́стья.
| Countable → gen PLURAL | Mass/abstract → gen SINGULAR |
|---|---|
| мно́го друзе́й (many friends) | мно́го сча́стья (much happiness) |
| не́сколько ошибо́к (several mistakes) | ма́ло са́хара (little sugar) |
| ско́лько столо́в? (how many tables?) | ско́лько воды́? (how much water?) |
| мно́го книг (a lot of books) | мно́го рабо́ты (a lot of work) |
У него́ мно́го друзе́й, но ма́ло свобо́дного вре́мени.
He has many friends but little free time. (друзе́й — gen plural, countable; вре́мени — gen singular, abstract)
В э́том упражне́нии сли́шком мно́го ошибо́к.
There are too many mistakes in this exercise. (оши́бка → genitive plural ошибо́к, with a fleeting vowel)
Жела́ю тебе́ мно́го сча́стья и здоро́вья!
I wish you much happiness and health! (сча́стье, здоро́вье → genitive singular — abstract masses)
Measure nouns: kilo, bottle, cup, group
Container and measure words behave exactly like quantity words: the measure comes first, the substance or items follow in the genitive — singular for a mass, plural for countables:
Купи́, пожа́луйста, килогра́мм я́блок и литр молока́.
Please buy a kilo of apples and a litre of milk. (я́блоки → gen plural я́блок, countable; молоко́ → gen singular молока́, mass)
К у́жину откро́ем буты́лку вина́.
We'll open a bottle of wine with dinner. (вино́ → genitive singular вина́)
Мо́жно ча́шку ко́фе и стака́н воды́?
Could I have a cup of coffee and a glass of water? (ко́фе is indeclinable; вода́ → genitive воды́)
На экску́рсию прие́хала больша́я гру́ппа студе́нтов.
A large group of students came on the excursion. (студе́нты → genitive plural студе́нтов, countable)
These overlap with the "cup of tea" possession-style phrases on genitive: possession and 'of' and with the "some" reading of the partitive genitive — the case is the same; only the nuance differs.
A note on numerals (the related rule)
Quantity words and numbers both demand the genitive, but numbers split the cases by their last digit — a separate, sharper rule that the Numbers pages cover in full. In brief:
- 1 (and compounds ending in 1) → nominative: одна́ кни́га (one book), два́дцать одна́ кни́га (twenty-one books).
- 2, 3, 4 (and compounds ending in 2/3/4) → genitive SINGULAR: две кни́ги, три стола́, два́дцать два до́ма.
- 5 and up (5–20, and anything ending in 5–9 or 0) → genitive PLURAL: пять книг, де́сять столо́в, сто рубле́й.
На по́лке две кни́ги и пять журна́лов.
There are two books and five magazines on the shelf. (2 → gen singular кни́ги; 5 → gen plural журна́лов)
Э́то сто́ит два́дцать два рубля́ и́ли сто рубле́й?
Does it cost twenty-two roubles or a hundred roubles? (…два → gen singular рубля́; сто → gen plural рубле́й)
This is the famous 2–4 genitive singular / 5+ genitive plural numeral rule. It is genuinely different from the quantity-word rule above (where the count/mass meaning, not a digit, picks singular vs plural), so keep the two systems apart. The full machinery is on the numeral government rule and case after numbers.
Common Mistakes
❌ У меня́ мно́го кни́ги.
Incorrect — мно́го requires the genitive; for a countable noun that means the genitive PLURAL книг, not the nominative plural кни́ги.
✅ У меня́ мно́го книг.
I have a lot of books. (мно́го + genitive plural книг)
❌ Ско́лько вре́мя?
Incorrect as a quantity question — after ско́лько the noun goes genitive. (As an idiom 'what time is it' Russians say Ско́лько вре́мени? anyway.)
✅ Ско́лько у нас вре́мени?
How much time do we have? (вре́мя → genitive singular вре́мени)
❌ В реке́ мно́го во́ды.
Incorrect — вода́ is a mass noun, so мно́го takes the genitive SINGULAR воды́; a plural form is impossible here.
✅ В реке́ мно́го воды́.
There's a lot of water in the river. (mass noun → genitive singular воды́)
❌ Купи́ килогра́мм я́блоки.
Incorrect — the measure noun килогра́мм governs the genitive plural of the countable: я́блок.
✅ Купи́ килогра́мм я́блок.
Buy a kilo of apples. (я́блоки → genitive plural я́блок)
❌ не́сколько друзья́
Incorrect — не́сколько ('several') takes the genitive plural; друг → друзе́й.
✅ Я пригласи́л не́сколько друзе́й.
I invited several friends. (не́сколько + genitive plural друзе́й)
Key Takeaways
- All quantity words — мно́го, ма́ло, немно́го, не́сколько, ско́лько, сто́лько, бо́льше, ме́ньше — govern the genitive. The frequent learner error is dropping the case, not mishandling it.
- Choose singular vs plural by countability: countable → genitive plural (мно́го книг); mass/abstract → genitive singular (мно́го воды́, ма́ло вре́мени).
- Measure nouns work the same way: килогра́мм я́блок, буты́лка вина́, ча́шка ко́фе, гру́ппа студе́нтов.
- This is distinct from the numeral rule, where the last digit decides: 1 → nominative, 2–4 → genitive singular, 5+ → genitive plural (две кни́ги, пять книг).
- English collapses the split into much/many without touching the noun; Russian changes the noun's number instead.

- Genitive: FormsA2 — The genitive (роди́тельный паде́ж) is one of the most-used and most-varied cases. The singular is tidy: masc/neuter -а/-я (стола́, окна́, музе́я), feminine -ы/-и (кни́ги, неде́ли, но́чи). The plural is the single hardest ending set in Russian — a three-way split between zero ending (often with a fleeting vowel: книг, о́кон, де́вушек), -ов/-ев (столо́в, музе́ев, отцо́в), and -ей (ноже́й, словаре́й, ноче́й). Learn the decision procedure, not a word list.
- The Partitive GenitiveB1 — Russian uses the genitive to mean 'some of / a quantity of' a mass noun, against the accusative for the whole, definite amount: Нале́й воды́ (pour some water) vs Я вы́пил во́ду (I drank the water). It maps roughly to English some vs the. A handful of masculine mass nouns keep an old partitive ending in -у/-ю (ча́шка ча́ю, кусо́к са́хару) — now colloquial and recessive, but worth recognising.
- Quantifiers: Много, Мало, Несколько, СколькоA2 — The vague-quantity words мно́го ('much/many'), ма́ло ('little/few'), немно́го ('a little'), не́сколько ('several'), ско́лько ('how much/many'), and сто́лько ('so much/many') all GOVERN THE GENITIVE: genitive plural for countables (мно́го книг, не́сколько дней) and genitive singular for mass nouns (мно́го воды́). When such a phrase is the subject, the past-tense verb goes NEUTER SINGULAR (Пришло́ мно́го люде́й). This page also separates the adverb-quantifier мно́го (+ genitive) from the declinable adjective мно́гие ('many people / many of them').
- The Numeral Government Rule in DepthA2 — The single most important rule in Russian numbers, stated definitively for the nominative/accusative: a number ending in 1 (except 11) puts the noun in the NOMINATIVE SINGULAR (два́дцать оди́н дом); ending in 2, 3, 4 (except 12–14) → GENITIVE SINGULAR (два до́ма, три рубля́); ending in 0, 5–9, or being 11–14 → GENITIVE PLURAL (пять домо́в, двена́дцать книг). Plus where the rule comes from (the genitive singular is a fossilized dual), how adjectives agree inside a numeral phrase (два больши́х до́ма), and how compounds key on the final word (сто оди́н дом).
- Case After NumbersA2 — Russia's famous numeral-government rule, viewed from the case angle: 1 takes the nominative singular (одна́ кни́га), 2/3/4 take the genitive SINGULAR (две кни́ги, три стола́), and 5 and up take the genitive PLURAL (пять книг). In compound numbers the LAST digit decides — два́дцать одна́ кни́га, два́дцать две кни́ги, два́дцать пять книг — and in oblique cases the whole phrase declines together (с двумя́ друзья́ми, о пяти́ кни́гах). The gen-sg-after-2/3/4 is a frozen relic of the old dual number, which is exactly why it feels so unlike the 5+ rule.
- Genitive: Possession and 'of'A2 — The genitive's flagship job: expressing both the English possessive ('s) and the preposition 'of' at once. There is no apostrophe and no separate 'of' word — possession is shown purely by putting the owner in the genitive AFTER the thing owned: маши́на отца́ (father's car / the car of the father), центр го́рода (the centre of the city). The whole possessor phrase declines, not just its head.
