Polish plurals, and the split nobody warns you about
Polish plurals are mostly predictable, and then there is one division that has no counterpart in Ukrainian or Russian: the language treats groups of men differently from groups of everything else — women, animals, objects and ideas alike.
The two plural genders
Polish collapses its three singular genders into two plural ones. The first, called masculine-personal, is for groups that include at least one man. The second is for everything else — and 'everything else' genuinely means everything: women, children, cats, tables, ideas.
The division reaches further than the noun. The pronoun changes, the adjective changes, and the past tense verb changes — which is why one man joining a group rewrites the whole sentence.
| Group | They | were | Example |
|---|---|---|---|
| includes a man | oni | byli | studenci, Polacy |
| everything else | one | były | studentki, koty, stoły |
Moi koledzy byli w pracy.
My colleagues were at work. — men
Moje koleżanki były w pracy.
My colleagues were at work. — women
The endings
Feminine and neuter are the easy part and will look familiar. Masculine is where the work is, because the ending depends on whether the noun refers to a man.
| Singular | Plural | Note |
|---|---|---|
| kobieta | kobiety | feminine: -a becomes -y |
| okno | okna | neuter: -o becomes -a |
| stół | stoły | masculine thing: -y |
| kot | koty | an animal is not a man: -y |
| student | studenci | a man: the consonant softens |
| Polak | Polacy | a man: k becomes c |
Counting changes the case
Polish counts the way your language does: two, three and four take the plain plural, while five and up take the genitive plural. The last digit decides, so twenty-two goes back to the plural and twenty-five returns to the genitive.
dwa koty · pięć kotów
two cats · five cats
trzy kobiety · sześć kobiet
three women · six women
Why this is worth getting right
Because it is audible. Most case errors make a sentence slightly off; using one where oni belongs makes a Pole hear immediately that you have called a group of men something else. It is the single grammatical feature that most marks a foreign speaker, and it is also completely mechanical once you have the habit.
Mistakes people make
Studenci były na wykładzie. → Studenci byli na wykładzie.
Studenci is a group of men, so the verb takes -li. Only groups without men take -ły.
Moje koty byli w domu. → Moje koty były w domu.
Animals are not men, whatever their own gender. Cats take the -ły form.
pięć koty → pięć kotów
From five upwards the counted noun goes into the genitive plural, exactly as in your language.

Questions people ask
What if I do not know whether the group includes men?
Polish defaults to the masculine-personal form for a group that might include men — a crowd, an unknown audience, people in general. The -ły form is for groups you know contain no men.
Does this affect anything besides the verb?
Yes — the pronoun (oni or one), the adjective, and the noun's own ending all follow the same split. It is one decision that propagates through the whole sentence, which is why it is worth making it first and building the sentence around it.
