Cardinal Numbers 0-20 | Polish Grammar

Counting to twenty in Polish looks deceptively simple — a list of words to memorise — but two of those words, jeden ('one') and dwa ('two'), already drag you into the heart of the Polish gender system, and the moment you reach pięć ('five') the noun you are counting changes its ending. This page gives you the full list, flags the gender forms early so they never surprise you, and shows the case shift in action so that even your first counting sentences are correct.

The numbers 0 to 10

Here is the core list. Learn the spelling exactly — every accented letter and digraph is part of the word.

Numeral	Polish	Notes
0	zero	neuter noun; indeclinable in counting
1	jeden / jedna / jedno	agrees in gender
2	dwa / dwie	agrees in gender
3	trzy
4	cztery
5	pięć	governs genitive plural
6	sześć
7	siedem
8	osiem
9	dziewięć
10	dziesięć

Pay attention to the nasal vowels and digraphs: pięć has ę, sześć has the digraph sz plus ść, dziewięć and dziesięć both contain dzi and ę. These are not optional decorations — piec (without the ę) is a different word entirely ('oven, to bake').

Mam tylko pięć złotych, to za mało na bilet.

I only have five złoty, that's not enough for a ticket.

Spotkajmy się o siódmej — nie, lepiej o ósmej.

Let's meet at seven — no, better at eight.

'One' agrees in gender: jeden, jedna, jedno

English says one book, one man, one window with a single invariant word. Polish cannot. Jeden behaves like an adjective and takes the gender of the noun it counts:

masculine: jeden — jeden kot (one cat), jeden dzień (one day)
feminine: jedna — jedna kobieta (one woman), jedna godzina (one hour)
neuter: jedno — jedno okno (one window), jedno dziecko (one child)

Zostało nam już tylko jedno jabłko i jedna gruszka.

We've only got one apple and one pear left.

Daj mi jeden bilet, proszę.

Give me one ticket, please.

This is your first signal that in Polish number and gender are inseparable. You cannot say jeden before kobieta — it has to be jedna. The reflex of always pairing the right form is something you build from day one.

'Two' has two basic forms: dwa and dwie

The number two splits by gender as well, and this is the form English speakers forget most often:

dwa — masculine non-personal (animals and things) and neuter: dwa koty (two cats), dwa okna (two windows)
dwie — feminine: dwie kobiety (two women), dwie godziny (two hours)

Kupiłam dwie kawy i dwa croissanty.

I bought two coffees and two croissants.

Mam dwa pytania i dwie prośby.

I have two questions and two requests.

There is a third form, dwaj / dwóch, used for counting groups of men (the masculine-personal forms). It is genuinely difficult and gets its own page — see Gender in Numbers. For now, just lock in dwa for things and animals, dwie for feminine nouns.

💡

From trzy (3) and cztery (4) upwards the numbers stop changing for gender in everyday speech — except for the special "counting men" forms. So the gender headache for counting is concentrated almost entirely in jeden and dwa/dwie. Master those two and most counting becomes mechanical.

The teens: the -naście family (11-19)

The teens are built on a recognisable pattern: a reduced form of the unit digit + -naście. The element -naście descends from an old phrase meaning "on ten", much like English -teen means "ten". Learn them as a rhythmic chant:

Numeral	Polish
11	jedenaście
12	dwanaście
13	trzynaście
14	czternaście
15	piętnaście
16	szesnaście
17	siedemnaście
18	osiemnaście
19	dziewiętnaście

Watch the irregular stems: 11 is jeden*aście (not *jedennaście), 14 drops to cztern- (not czter-), 15 is pi*ętnaście with ę, 16 contracts to *szes- (not sześć-), and 19 is *dziewięt*naście with ę. None of the teens agree in gender — they are fixed forms.

Mój syn ma piętnaście lat, a córka dwanaście.

My son is fifteen and my daughter is twelve.

W lodówce zostało jeszcze szesnaście jajek.

There are still sixteen eggs left in the fridge.

Twenty: dwadzieścia

The number twenty, dwadzieścia, opens the "tens" series and is built from dwa + an old form of dziesięć. Note the ś — it is dwadzie*ś*cia, not dwadziescia. The rest of the tens (thirty, forty, and so on) are covered on the Tens, Hundreds, Thousands page.

Do końca miesiąca zostało dwadzieścia dni.

There are twenty days left until the end of the month.

The counted noun changes case — even here

This is the single biggest structural surprise for English speakers, so meet it now in miniature. The noun you are counting takes a different case depending on the number:

1 → nominative singular: jeden kot (one cat)
2, 3, 4 → nominative plural: dwa koty, trzy koty, cztery koty (two/three/four cats)
5 and above (including the teens) → genitive plural: pięć kotów, dziesięć kotów, jedenaście kotów (five/ten/eleven cats)

So a single noun appears in three shapes — kot, koty, kotów — purely because of the number in front of it. English keeps cats identical the whole way up; Polish does not.

Jeden samochód, dwa samochody, pięć samochodów — łatwo się pomylić.

One car, two cars, five cars — it's easy to get it wrong.

Na stole leży pięć książek i jedna gazeta.

There are five books and one newspaper lying on the table.

The deep logic is worth a sentence: from five up, the number behaves like a noun meaning a quantity of something, and "of something" in Polish is the genitive — so pięć kotów is literally "a five of cats". Two, three and four predate this counting logic and keep an older agreement pattern (nominative plural), which is why the boundary falls right at five. The full rule and the case forms live on the Numeral Case Government and Genitive After Numbers pages; here, just notice that the noun is not invariant.

💡

A quick self-check for any number up to twenty: ask "is the unit 2, 3 or 4?" If yes, use the plural that looks like the basic plural (koty, kobiety). If the number is 5-20, switch to the genitive plural (kotów, kobiet). One is its own case (singular).

Common Mistakes

❌ Mam jeden siostrę.

Incorrect — 'one' must agree with the feminine noun.

✅ Mam jedną siostrę.

I have one sister.

(Siostra is feminine, so 'one' is jedna — and in the accusative object position it becomes jedną. English's invariant 'one' gives no warning that the form must change.)

❌ Kupiłem dwa kawy.

Incorrect — 'coffee' is feminine, so 'two' must be dwie.

✅ Kupiłem dwie kawy.

I bought two coffees.

❌ Mam pięć koty.

Incorrect — five governs the genitive plural, not the nominative plural.

✅ Mam pięć kotów.

I have five cats.

(This is the classic transfer error: English keeps the noun in one form regardless of the number, so learners leave the noun in the dwa koty shape and forget the switch to kotów at five.)

❌ On ma dwanaście rok.

Incorrect — twelve takes the genitive plural lat, not a singular.

✅ On ma dwanaście lat.

He is twelve years old.

(The teens (11-19) all behave like 5+, so they take the genitive plural — and 'years' in counting uses the irregular lat, not roków.)

❌ Daj mi jeden minutę.

Incorrect — 'minute' is feminine; 'one' must be jedna.

✅ Daj mi jedną minutę.

Give me one minute.

Key Takeaways

The list 0-20 must be memorised with exact diacritics: pięć, sześć, dziewięć, dziesięć, piętnaście, dwadzieścia.
Jeden agrees fully (jeden / jedna / jedno); dwa splits into dwa (masculine non-personal + neuter) and dwie (feminine).
The teens -naście and the number dwadzieścia are fixed, ungendered forms.
The counted noun shifts case: 1 → nominative singular, 2-4 → nominative plural, 5-20 → genitive plural. This starts immediately, not "later".
