Biernik: the Polish accusative case
If you learn one case after być, learn this one. The accusative is what almost every ordinary verb takes: what you have, like, see, buy, read, order. Four endings cover it, and for a Slavic speaker three of them are already familiar.
The four endings
Which ending a noun takes depends on its gender — and, for masculine nouns, on whether it is alive. That animacy split is the only part that is genuinely new if you already speak Ukrainian or Russian, and even there the idea is the same one your own language uses.
| Noun | Change | Example |
|---|---|---|
| feminine in -a | -a → -ę | kawa → kawę |
| masculine, not alive | no change | chleb → chleb |
| neuter | no change | okno → okno |
| masculine, alive | like the genitive: -a | kot → kota |
Lubię kawę.
I like coffee.
Poproszę chleb.
I'll have some bread.
Widzę kota.
I see a cat.
The verbs that take it
Not a list to memorise — a default. If a verb has a direct object, that object is in the accusative unless something makes it otherwise. mieć, lubić, widzieć, znać, kupować, czytać, jeść, pić, poprosić: all of them.
One useful exception early on: lubić followed by another verb needs no case at all — the second verb simply stays in its dictionary form. Lubię czytać.
Mam siostrę.
I have a sister.
Lubię czytać.
I like reading. — no case, just the plain verb
The adjective follows the noun
Whatever the noun does, the adjective in front of it does too. Feminine takes -ą, and the masculine and neuter forms follow the same no-change or genitive-like pattern as the noun.
Piję czarną kawę.
I drink black coffee.
Mam duży dom.
I have a big house.
Negation switches the case
This is the rule that catches everyone. Put nie in front of the verb and the object stops being accusative and becomes genitive. Mam czas becomes Nie mam czasu — not Nie mam czas.
Ukrainian and Russian do the same thing, but optionally — both «не маю часу» and a nominative-ish alternative sound acceptable. In Polish it is not optional. Every negated direct object goes genitive, every time.
Mam czas. → Nie mam czasu.
I have time. → I have no time.
Lubię kawę. → Nie lubię kawy.
I like coffee. → I don't like coffee.
Mistakes people make
Lubię kawa. → Lubię kawę.
A feminine noun after a verb takes -ę. The dictionary form only survives as the subject of a sentence.
Widzę pies. → Widzę psa.
A masculine noun that is alive behaves like the genitive: pies becomes psa. A table, being not alive, would not change.
Nie mam czas. → Nie mam czasu.
Negation moves the object out of the accusative and into the genitive. There is no exception to this.

Masculine and not alive: no change at all.
Negate it: Mam pieniądze.
Negation pulls the object into the genitive.

Questions people ask
How do I know if a masculine noun counts as alive?
People and animals are alive; objects are not. Polish is stricter about this than it looks, and a few words sit on the line for historical reasons — Poles say mam laptopa, treating a laptop as animate in the spoken language. Learn those as you meet them; the rule covers everything else.
Is the Polish accusative the same as the Ukrainian one?
Closely enough that your instinct will usually be right, and not closely enough to stop checking. The feminine -ę matches your -у almost word for word, and the animacy rule works the same way. The real divergence is negation: Polish always switches to the genitive, where your language lets you choose.
