Grammar 14--Counting Things

In English when we count something we change the ending of its name:

one question
two questions
three questions

This is done in Russian too, but in a slightly more complex way. It looks like this:

оди́н вопро́сone question
два вопро́саtwo of question
три вопро́саthree of question
четыре вопро́саfour of question
пять вопро́совfive of questions
шесть вопро́совsix of questions

Notice how the wordвопросchanges:

One: nominative case and singular
A few (2--4): genitive case (but still singular!)
Many (5 or more): genitive plural

Compound Numbers

If a number is pronounced as multiple words, only the last part determines the number and case of the noun:

два́дцать оди́н вопро́сtwenty one questions
два́дцать два вопро́саtwenty two questions
два́дцать три вопро́саtwenty three questions
два́дцать четы́ре вопро́са twenty four questions
два́дцать пять вопро́совtwenty five questions

Special Forms of Small Numbers

один--the number one has gender and (astonishingly) a plural form which is used with plural-only nouns. Один is declined like этот:

У меня́ есть оди́н вопро́с.

I have one question.

У меня́ есть одна́ кни́га.

I have one book.

У меня́ есть одни́ ча́сы.

I have one clock.

Я ви́жу одну́ ко́шку.

I see one cat.

Я ви́жу одного́ челове́ка.

I see one man.

два, две--the number two has gender, but no plural form. It also has an animate accusative form:

У меня́ есть два вопро́са.

I have two questions.

У меня́ есть две кни́ги.

I have two books.

Я ви́жу двух люде́й.

I see two men.

три, четыре--the numbers three and four have an animate accusative form:

Я ви́жу трёх люде́й.I see three men.
Я ви́жу четырёх люде́й.I see four men.

Cases

The information above covers only the nominative and accusative cases. Most of the time this is all you need. The other cases are sometimes used in the Watchtower, particularly the genitive.

Counting Years

When counting years we switch from the word “год” to “лето” when we switch to the genitive plural:

Мне четы́ре го́да.I am four years old.
Мне пять лет.I am five summers old.
