Cases in the Plural
Every course quietly skips this lesson, and learners plateau exactly here. Not us. The genitive plural is the last real boss of Russian nouns — and you've been fighting it successfully since your first сто рублей.
The Money Rule, Finally Named
After 5+, много (many), мало (few) and сколько (how many), nouns take the genitive plural:
| Russian | English |
|---|---|
| пять рублей | five roubles — the shop pattern, explained at last |
| много людей | many people |
| мало времени | little time |
| Сколько дней? | How many days? |
Its Three Endings
| Noun type | Ending | Example |
|---|---|---|
| masculine (most) | -ов | стол → столов |
| masculine (soft/hushing) | -ей | рубль → рублей, друг → друзей |
| feminine -а / neuter -о | (drops away) | книга → книг, окно → окон |
The Tidy Rest
The other plural cases share one melody — learn the trio once:
| Case | Ending | Example |
|---|---|---|
| dative | -ам / -ям | Я даю детям книги. — I give the children books. |
| instrumental | -ами / -ями | Я гуляю с друзьями. — I stroll with friends. |
| prepositional | -ах / -ях | Мы говорим о книгах. — We talk about books. |
Your New Favourite Sentence
Нет проблем!
No problem!
Note: нет + genitive plural. You'll say it daily — and now you know exactly why it ends that way.
У тебя много друзей в Москве?
Do you have many friends in Moscow?
Да! Пять человек из университета, и мы часто гуляем с друзьями Анны.
Yes! Five from university, and we often go out with Anna's friends.
Common Mistakes
- много + nominative. Много люди → много людей. Quantity words herd nouns into the genitive plural.
- два рублей. The 2–4 slot takes the singular form: два рубля. Genitive plural starts at five.
- Forgetting the trio. Датам? Instrumentalах? The plural melody is -ам, -ами, -ах — one set for everything.
What You Can Do Now
You can count anything past four, quantify your life (много работы, мало времени), and speak about groups — с друзьями, о книгах, детям. The noun system is, at last, complete.
