The 1 / 2-4 / 5+ rule
The famous Slavic number rule.
| Number | Case of noun | Example |
|---|---|---|
| 1 | nominative singular | один стол |
| 2-4 | genitive singular | два стола |
| 5+ | genitive plural | пять столов |
| 21, 22... | by the last digit | двадцать один стол |
два (m/n) vs две (f).
In other cases, the number declines too.
