Accusative: Forms | Polish Grammar

The accusative (Polish biernik) is the case of the direct object — the thing directly acted on by the verb. It answers the questions kogo? ("whom?") and co? ("what?"). When you say I see a dog, I'm drinking coffee, I have a brother, the dog, the coffee and the brother all go into the accusative. This is one of the first cases you need, because almost every sentence with a transitive verb uses it. The catch for English speakers is that there is no single accusative ending: the form a noun takes depends on its gender and, for masculine nouns, on animacy. This page lays out all the patterns so you can build any accusative form on sight.

The big picture: four patterns, not one ending

English marks the object only on a handful of pronouns (I → me, he → him) and leaves nouns untouched: the dog is the dog whether it bites or is bitten. Polish marks the object on the noun itself, but the way it does so splits into four behaviours:

Noun type	What happens in the accusative	Nominative → Accusative
Feminine in -a	ending changes to -ę	kobieta → kobietę
Masculine inanimate	no change (= nominative)	dom → dom
Masculine animate	takes -a (= genitive)	kot → kota
Neuter	no change (= nominative)	okno → okno

The two things to actually memorise are the feminine -ę ending and the rule that masculine animate nouns borrow the genitive. Masculine inanimate and neuter nouns simply don't change — they're the easy ones. Let's take each in turn.

Feminine nouns in -a → -ę

The most distinctive accusative form belongs to feminine nouns ending in -a. They swap that -a for the nasal vowel -ę. This is the single most recognisable accusative signal in the language: when you hear a word end in -ę, it is almost always a feminine direct object.

Nominative	Accusative	Meaning
kobieta	kobietę	woman
kawa	kawę	coffee
książka	książkę	book
woda	wodę	water
siostra	siostrę	sister

Piję kawę bez cukru.

I drink coffee without sugar.

Czytam ciekawą książkę o Krakowie.

I'm reading an interesting book about Kraków.

Note the diacritic: it is ę (e with the ogonek, the little hook), not a plain e. Writing kobiete instead of kobietę is a spelling error that natives notice immediately. In careful or southern-regional speech the -ę is lightly nasalised; in everyday speech across most of Poland it is pronounced like a plain [e] word-finally — but you must still write the ogonek.

A small but important sub-group: feminine nouns ending in a soft consonant (like noc "night", rzecz "thing", miłość "love") don't change at all in the accusative. They look identical to the nominative.

Mam dla ciebie jedną rzecz do powiedzenia.

I have one thing to tell you.

Masculine inanimate → no change

Masculine nouns naming non-living things (a house, a table, a car, a film) keep their nominative form in the accusative. There is nothing to add; the object looks exactly like the subject would.

Nominative = Accusative	Meaning
dom	house
stół	table
samochód	car
film	film
chleb	bread

Kupiłem nowy samochód.

I bought a new car.

Oglądamy dzisiaj wieczorem stary film.

We're watching an old film this evening.

Keep the diacritics in the stem: stół and samochód have ó, not o, even though the ending doesn't move.

Masculine animate → genitive-like -a

Here is the pattern English cannot prepare you for. Masculine nouns naming living beings — people and animals — take the genitive ending in the accusative, which for most of them is -a (or -ego for the soft/extended type and for many surnames). So the direct-object form of pies "dog" is psa, the same word you'd use to say koniec psa "the end of the dog."

Nominative	Accusative (= genitive)	Meaning
kot	kota	cat
pies	psa(fleeting -e- drops)	dog
student	studenta	student
brat	brata	brother
nauczyciel	nauczyciela	teacher

Mam brata i dwie siostry.

I have a brother and two sisters.

Widzę psa na podwórku.

I see a dog in the yard.

Notice pies → psa: the -e- in the stem is a "fleeting vowel" that vanishes once an ending is added. This is regular and you'll see it on many masculine nouns (pies/psa, chłopiec/chłopca, ojciec/ojca).

💡

The masculine accusative is really two questions in one: Is this noun masculine? and Is it alive? If it's a living masculine being, reach for the genitive form. If it's a thing, leave it alone. This animacy split has no parallel in English and is worth drilling until it's automatic — see the dedicated animacy rule page, which also covers the "honorary animate" objects (mam mercedesa, jem banana).

Neuter → no change

Neuter nouns (those ending in -o, -e, -ę, -um) never change in the accusative singular. Subject and object look identical.

Nominative = Accusative	Meaning
okno	window
dziecko	child
mieszkanie	flat / apartment
imię	(first) name

Otwórz okno, jest gorąco.

Open the window, it's hot.

Wynajmujemy małe mieszkanie w centrum.

We're renting a small flat in the centre.

Adjectives agree with the noun

An adjective modifying an accusative noun must match it in gender, number and case. The endings follow the same four-way logic:

Gender / type	Adjective accusative	Example
Feminine	-ą	dobrą kawę (good coffee)
Masculine inanimate	-y / -i (= nom.)	dobry dom (a good house)
Masculine animate	-ego (= gen.)	dobrego psa (a good dog)
Neuter	-e (= nom.)	dobre wino (good wine)

Znam tę miłą dziewczynę z pracy.

I know that nice girl from work.

Mam starszego brata i młodszą siostrę.

I have an older brother and a younger sister.

Two things to flag here. First, the feminine adjective ending is -ą (a with the ogonek), e.g. dobrą, miłą, starą — diacritic required. Second, the demonstrative ta "this/that (fem.)" has a special accusative tę (formal/written) — in everyday speech tą is extremely common and widely accepted, but tę is the textbook form: tę książkę, tę kobietę.

💡

For masculine-animate nouns, the noun ends in -a but the adjective ends in -ego: widzę dobrego psa, znam nowego nauczyciela. The two endings look different but are working together — both are genitive forms borrowed into the accusative. Don't try to make them rhyme.

Plurals: a one-line preview

In the plural, the four-way split collapses into a simpler two-way one based on masculine-personal gender. Nouns denoting groups of men (or mixed-gender people) take a genitive-like accusative; everything else (women, animals, things, of all genders) uses the nominative plural form. So widzę studentów "I see (male/mixed) students" but widzę książki "I see books" and widzę kobiety "I see women." This deserves its own treatment — see the masculine-personal plural page. For now, just know the singular rules above are your A1 priority.

Common Mistakes

❌ Piję kawa.

Incorrect — kawa is a feminine direct object and must take -ę.

✅ Piję kawę.

I'm drinking coffee.

❌ Mam brat.

Incorrect — brat is masculine animate, so the accusative is brata.

✅ Mam brata.

I have a brother.

❌ Widzę pso.

Incorrect — there's no -o ending here; masculine animate takes the genitive form psa.

✅ Widzę psa.

I see a dog.

❌ Kupiłem nowego samochodu.

Incorrect — samochód is inanimate, so it stays in the nominative form; the -ego/-u genitive is wrong here.

✅ Kupiłem nowy samochód.

I bought a new car.

❌ Czytam dobry książkę.

Incorrect — the adjective must be feminine -ą to agree with książkę.

✅ Czytam dobrą książkę.

I'm reading a good book.

Key Takeaways

There is no single accusative ending — the form depends on gender and animacy.

Masculine inanimate and neuter nouns don't change (dom, okno).
Masculine animate nouns borrow the genitive (kot → kota, pies → psa).
Adjectives agree: feminine -ą, masculine-animate -ego, masculine-inanimate/neuter unchanged.
