Test yourself

The Russian noun and number agreement tool picks the correct form of a Russian noun after a number: 1 яблоко, 2 яблока, 5 яблок, 21 год, 12 лет. It shows the rule and a table of forms for different numbers.

The rule

The form of the noun depends on the last two digits of the number:

Number ends in	Form	Example
1 (except 11)	nominative singular	1, 21, 101 рубль
2, 3, 4 (except 12–14)	genitive singular	2, 33, 104 рубля
0, 5–9, 11–14	genitive plural	5, 11, 100 рублей

After a decimal number the noun is in the genitive singular: 2,5 литра.

Tricky words

год — 5 лет, человек — 5 человек, раз — 5 раз, ребёнок — 5 детей;
глаз, сапог, солдат, чулок have a zero ending in the genitive plural: пять сапог.

For developers pluralizing Russian strings: if n % 100 is 11–14, use the third form; otherwise n % 10 = 1 gives the first form, 2–4 the second, anything else the third.
