Grammar Sheet
How Russian numbers work, one small rule at a time. Tap any Russian word to hear it.
2
One and two change with gender
1 has three forms (один, одна, одно) and 2 has two (два, две). They match the gender of the thing you count. No other number does this.
3
Counting things: the 1 / 2-4 / 5+ rule
The word after a number changes its ending. Only the last digits of the number matter. Change the number and the thing to see the rule work.
Ends in 1 (but not 11)
Ends in 2, 3 or 4 (but not 12, 13, 14)
Everything else: 0, 5 to 20, 25 to 30...
4
Thousands and millions
тысяча (thousand) is itself a feminine word, so it follows rule 3 and takes одна / две. миллион is masculine, so it takes один / два.
5
First, second, third...
Ordinal numbers behave like adjectives: the ending matches the gender of the noun. In a longer number only the last word changes: двадцать первый (21st).

Spelling and sound tips
Small things that trip up most learners. Tap the underlined words to hear them.
- Soft sign at the end for 5 to 20 and 30: , , , .
- Soft sign in the middle for 50 to 80 and 500 to 900: , , . A number never has both.
- No "and" between the parts: 105 is , never "сто и пять".
- Unstressed "о" sounds like "a": is said "adín" and is "adínnatsat'".
- Zero has two words: is the everyday one and appears in some set phrases.
