When you put a number in front of a Ukrainian noun, the noun does not just sit there in the plural the way English "five tables" works. It changes form, and which form depends on the number in a three-way pattern that governs every counted noun in the language. This page previews that pattern so you can build correct counted phrases from A2 onward; the full machinery (declining the numeral itself, agreement details, мільйон vs тисяча behaviour) lives on the numeral agreement page. The single most important thing to take away: after 2, 3, 4 Ukrainian uses the nominative plural — два столи́, not the Russian genitive singular — and that one fact instantly marks your Ukrainian as authentic.
The three-way pattern
Every number falls into one of three slots, and the slot decides the noun's form.
| Number | Noun form | Example |
|---|---|---|
| 1 (and …1) | nominative singular | оди́н стіл, два́дцять одна́ кни́га |
| 2, 3, 4 (and …2/…3/…4) | nominative plural (often with end-stress) | два столи́, три кни́ги, чоти́ри вікна́ |
| 5 and up (5–20, then …5–…9, 0) | genitive plural | п’ять столі́в, де́сять книг, сто ві́кон |
Read that table as the whole grammar of counting in miniature. The rest of the page just unpacks each row with examples and the reasoning behind it.
After 1: nominative singular
The number оди́н "one" is really an adjective — it agrees in gender with the noun and leaves it in the nominative singular. So "one" behaves exactly as you'd expect: just a singular noun.
У ме́не лиши́вся оди́н уро́к, і на сього́дні я ві́льна.
I've got one lesson left, and then I'm free for today. (оди́н уро́к — nominative singular.)
Crucially, this applies to any compound number ending in 1, even huge ones, because only the final word counts:
На по́лиці рі́вно два́дцять одна́ кни́га — я перерахува́ла дві́чі.
There are exactly twenty-one books on the shelf — I counted twice. (…одна́ кни́га: singular, because the number ends in 1, even though there are 21 of them.)
After 2, 3, 4: nominative plural — the Ukrainian hallmark
Here is the form that distinguishes Ukrainian. After два / дві, три, чоти́ри, the noun goes into the nominative plural — the same form you'd use to list them without a number — and very often the stress jumps onto the ending.
На ку́хні стоя́ть два столи́: оди́н для готува́ння, оди́н для їжі.
There are two tables in the kitchen: one for cooking, one for eating. (два столи́ — nominative plural, stress on the ending: сто-ЛИ.)
Я прочита́в три кни́ги за цей ти́ждень — давно́ так не було́.
I've read three books this week — it's been a long time since that happened. (три кни́ги — nominative plural.)
У кла́сі чоти́ри вікна́, і всі вихо́дять на двір.
There are four windows in the classroom, and all of them face the yard. (чоти́ри вікна́ — neuter nominative plural.)
Why the nominative plural, and why the stress shift? Historically this slot is the old dual number (the form Slavic languages once used for "exactly two"). When the dual died out, its endings merged with the nominative plural in Ukrainian — but the dual stress pattern survived, which is why so many of these forms put the accent on the ending: два столи́, дві сестри́, три відра́. So the modern rule is "nominative plural after 2/3/4," with a stress quirk inherited from a number category that no longer exists.
У ме́не дві сестри́ і оди́н брат — на жаль, всі живу́ть дале́ко.
I have two sisters and one brother — unfortunately they all live far away. (дві сестри́ — note the end-stress, sister sg. сестра́.)
A note on gender for 2: два vs дві
The number 2 itself agrees in gender: два before masculine and neuter nouns (два столи́, два вікна́), дві before feminine nouns (дві кни́ги, дві сестри́). The numbers 3 and 4 have a single form (три, чоти́ри) regardless of gender.
Дай мені́ дві хвили́ни — я ті́льки взу́юся.
Give me two minutes — I just need to put my shoes on. (дві хвили́ни — feminine, so дві not два.)
After 5 and up: genitive plural
From п’ять "five" upward, the noun switches to the genitive plural — the case of quantity. This holds for 5–20, then resumes from compounds ending in 5–9 and 0.
У хо́лодильнику ще п’ять яє́ць — на омле́т ви́стачить.
There are still five eggs in the fridge — enough for an omelette. (п’ять яє́ць — genitive plural.)
Я взяла́ де́сять книг у бібліоте́ці, тепе́р не зна́ю, що чита́ти пе́ршим.
I borrowed ten books from the library, now I don't know what to read first. (де́сять книг — genitive plural, here with a zero ending.)
На ма́йдані зібра́лося сто люде́й, мо́же й бі́льше.
A hundred people gathered in the square, maybe more. (сто люде́й — genitive plural.)
The genitive plural is the form learners most often get wrong, because it interacts with fleeting vowels (вікно́ → ві́кон) and the о/і alternation (нога́ → ніг). That form-building is taught in Genitive Plural Forms; here, just register that 5+ pulls the genitive plural.
A worked count: 1 → 5
Watch one noun travel through all three slots:
| Number | Phrase | Form |
|---|---|---|
| 1 | оди́н стіл | nominative singular |
| 2 | два столи́ | nominative plural (end-stress) |
| 3 | три столи́ | nominative plural |
| 4 | чоти́ри столи́ | nominative plural |
| 5 | п’ять столі́в | genitive plural |
Notice the vowel: the singular стіл has і, but every counted form (столи́, столі́в) restores the underlying о, because adding an ending opens the syllable. That о/і swing is the closed-syllable alternation, and it shows up the moment you start counting.
Source-language comparison: the Russian difference
For an English speaker, the shock is simply that the noun changes shape at all — and three different ways. English keeps one plural ("five tables, ten tables"); Ukrainian asks you to track which of three forms the number selects.
For a Russian speaker, the danger is a near-miss that sounds wrong to natives. After 2/3/4, Russian uses the genitive singular (два стола, три книги with a genitive-singular ending), but Ukrainian uses the nominative plural (два столи́, три кни́ги). The phrases look deceptively similar but the grammar is different, and the stress is different too:
| Ukrainian (nom. pl.) | Russian (gen. sg.) — contrast | |
|---|---|---|
| 2 tables | два столи́ | (Russian: два стола́) |
| 2 sisters | дві сестри́ | (Russian: две сестры́) |
| 3 brothers | три бра́ти | (Russian: три бра́та) |
The 5+ slot, by contrast, is genitive plural in both languages, so that one doesn't trip up a Russian speaker — it's the 2/3/4 slot that does.
Common Mistakes
❌ два стола́ (Russian-style genitive singular)
Incorrect — Ukrainian uses the nominative plural after 2/3/4: два столи́, with the stress on the ending.
✅ два столи́
two tables — nominative plural.
❌ п’ять столи́ (nominative plural after 5)
Incorrect — 5 and above take the genitive plural: п’ять столі́в.
✅ п’ять столі́в
five tables — genitive plural.
❌ два́дцять одні́ кни́ги (plural after a number ending in 1)
Incorrect — a number ending in 1 takes the nominative singular: два́дцять одна́ кни́га.
✅ два́дцять одна́ кни́га
twenty-one books — singular, because the number ends in 1.
❌ два кни́ги (using два with a feminine noun)
Incorrect — before a feminine noun the number 2 is дві: дві кни́ги.
✅ дві кни́ги
two books — feminine, so дві.
❌ чоти́ри вікон (genitive plural after 4)
Incorrect — 4 takes the nominative plural, not the genitive: чоти́ри вікна́.
✅ чоти́ри вікна́
four windows — nominative plural.
Key Takeaways
- Numbers select one of three noun forms: 1 → nominative singular, 2/3/4 → nominative plural, 5+ → genitive plural.
- The form is chosen by the last word of the number: 21 ends in 1, so два́дцять одна́ кни́га (singular).
- After 2/3/4 the noun is the nominative plural with frequent end-stress: два столи́, дві сестри́, три відра́ — this is the Ukrainian hallmark, not the Russian genitive singular.
- The number 2 has gender: два (m/n) vs дві (f); 3 and 4 don't.
- From 5 up, the noun is the genitive plural (п’ять столі́в, де́сять книг), the form that interacts with fleeting vowels and the о/і alternation.

- Numeral–Noun Agreement (The Hard Part)B1 — The notorious three-way rule: after 1 (and …1) the noun is nominative SINGULAR, after 2/3/4 (and …2/3/4) nominative PLURAL with the dual-reflex end-stress (два столи́, дві сестри́), and after 5+ genitive PLURAL — chosen by the LAST digit, and applying only when the whole phrase is nominative or inanimate-accusative.
- Forming the Nominative PluralA1 — The regular nominative plural in Ukrainian: hard stems take -и, soft and hushing stems take -і, neuters take -а/-я — and the choice follows stem hardness, while words like стіл→столи reveal the о/і alternation reversing as the syllable opens, a pattern with no Russian parallel.
- Genitive After Numbers and QuantityB1 — When numbers and quantity words trigger the genitive — numbers 5+ (and any number ending in 5–9 or 0) take the genitive PLURAL (п’ять столі́в, де́сять книг, сто гри́вень, два́дцять ро́ків), as do quantity words бага́то, ма́ло, кі́лька, скі́льки, тро́хи; fractions and полови́на/чверть take the genitive singular (полови́на я́блука) — all contrasted with the 2/3/4 rule that takes nominative plural, plus the suppletive рік→ро́ків and люди́на→люде́й you must drill as fixed combinations.
- Saying Numbers 0–100 AloudA1 — A practical reading-and-pronunciation drill for the numbers 0–100. The units нуль, оди́н–де́сять; the fused -на́дцять teens (одина́дцять, двана́дцять, чотирна́дцять… — all stressed on -на́-); the tens (два́дцять, три́дцять, со́рок, п’ятдеся́т, шістдеся́т, сімдеся́т, вісімдеся́т, дев’яно́сто, сто), where 50–80 are final-stressed -деся́т compounds; and the compounds (два́дцять оди́н, сімдеся́т ві́сім). The orthography is unavoidable: п’ять, шість, де́в’ять, ві́сім carry mandatory apostrophes and soft signs, and со́рок (40) and дев’яно́сто (90) are irregular.
- Plural-Only and Singular-Only NounsB1 — Some Ukrainian nouns are locked to one number: plurale tantum like двері, гроші, окуляри exist only in the plural and take plural agreement, while singularia tantum like молоко, щастя and the collective -я neuters like волосся, листя exist only in the singular — and the grammar often runs opposite to English.
- Special Counted Forms (2/3/4 and Stress)B2 — After два/три/чотири a Ukrainian noun takes the NOMINATIVE PLURAL — not the Russian genitive singular — and crucially the stress often jumps to the ending and differs from the plain plural (два столи́, три си́ни, дві сестри́): a surviving reflex of the lost dual number, the most distinctively Ukrainian corner of the case system, with the adjective wavering between nominative plural and genitive plural (два нові́ / нови́х столи́).
