Mianownik
the case of the name

Polish has seven cases. Mianownik — the nominative — is the first of them, the one every dictionary uses as its headword, and the one you meet in the grammar table’s first row. Its name comes from mianować, “to name”: it is the case that simply names a thing, without saying what is done to it, where it is, or who owns it.

Because it carries no relation, it is the case of the subject — the doer — and of the predicate noun after być and to. Every other case is, in a sense, the nominative plus a job.

The dictionary form

When you look a word up, the entry is the nominative singular: dom, not domu; ręka, not ręki. When you learn a noun you should still learn its gender with it, because gender is what tells you how to decline it — but the headword itself is always the nominative.

The same goes for adjectives (dobry) and for the citation of a noun inside a sentence. If you say „Kot” to rzeczownik, “kot is a noun”, the quoted word stays in the nominative because you are naming it, not using it.

The nominative has four jobs. Three of them are easy; the fourth — the predicate noun — is where English speakers trip, because English uses the same bare form after “is”, and Polish sometimes uses the instrumental instead.

1 · The subject

The doer of the sentence stands in the nominative. It decides the form of the verb, and in the past tense the form of the verb tells you the subject’s gender — which is why the plural split matters so much.

Kot śpi. · Kobieta czyta. · Dzieci się bawią. · Studenci piszą egzamin.

The cat is asleep. · The woman is reading. · The children are playing. · The students are taking an exam.

2 · The predicate noun after być — and the great to jest exception

This is the one rule in this section worth memorising word for word:

The distinction is between identifying and classifying. If the sentence points at one particular thing and says what it is, Polish uses to and the nominative. If it puts a person into a category, it uses być and the instrumental:

To jest mój brat. — identifying: to + nominative

On jest moim bratem. — classifying a person: instrumental

To jest dobra książka. — identifying a thing

Ta książka jest dobra. — adjective after być stays nominative; only nouns turn instrumental

3 · Naming and titles

Names, titles, headings, labels, captions, the name on a door, the title of a book: all nominative. Nothing is being done to them and they are not the subject of anything — they are simply named.

„Pan Tadeusz” · „Zbrodnia i kara” · Uniwersytet Warszawski · ulica Krakowska

A poem by Mickiewicz · Crime and Punishment · the University of Warsaw · Krakowska Street

Notice that in a Polish address or in an institution’s name the words stay nominative even though English would often use “of”: Uniwersytet Warszawski is literally “University Warsawian”, not “University of Warsaw”.

4 · The subject of a negated or impersonal sentence — carefully

Polish has sentences with no subject at all, and sentences where the “subject” is a dative experiencer. These are worth knowing because they are the exception to “the doer is nominative”:

Nie ma mleka. — no subject; the missing thing is genitive

Podoba mi się ten film. — literally “the film pleases itself to me”; the film is nominative

Trzeba wyjść. — no subject at all

In Podoba mi się ten film the verb agrees with film, not with mi — and that is the giveaway that film is the grammatical subject and therefore nominative, even though in English “I like the film” makes “I” look like the subject. The same shape appears in Podobają mi się te filmy.

You cannot build a correct nominative plural without knowing the gender, so this section comes first. Polish looks like it has three genders, and in the singular it does: masculine, feminine, neuter. But in the plural the masculine splits in two, and that split is the single most important fact about the nominative plural.

The five grammatical categories

Polish grammars work with five categories, because they are the ones that matter for endings. The two extra ones split the old “masculine” into people and everything else.

How to tell the gender

For most nouns the nominative ending gives it away:

The exceptions you will actually meet

In the singular the nominative has no ending to add. The nominative singular is the dictionary form. That sounds trivial, but it is genuinely useful: for nouns, the singular nominative never changes, so there is nothing to get wrong. What you need to learn instead is the gender, because the gender is what the plural endings depend on.

Nouns that only exist in the plural

Some nouns have no singular at all — plurale tantum. They are always plural, and their nominative is the only form you will use in this case. All the everyday ones name things, so they are non-masculine-personal — which is why they take były, never byli.

Drzwi są zamknięte. · Okulary są na stole. · Wakacje były wspaniałe.

The door is locked. · The glasses are on the table. · The holidays were wonderful.

Note były, not byli — these are non-personal plurals even though English says “the holidays were”.

Here is the whole system in one sentence: masculine-personal takes -i / -y / -e / -owie — often after the stem consonant has changed — and everything else takes -y / -i / -e and leaves the stem alone. The rest of this section is the detail behind that sentence.

Masculine-personal — the hard half

Masculine-personal nouns are the only ones whose plural ending depends on the sound before it, and they are the only ones where the stem can change shape. There are four endings — -i, -y, -e, -owie — and the choice is regular once you know the final consonant of the stem.

The -owie group: honour, kinship and a few titles

-owie is the old, dignified ending. It survives in words for people you respect or are related to, and in a handful of professions where both forms are accepted.

Irregular masculine-personal plurals — learn these as words

A small set of very common nouns does not follow any rule. They are frequent enough that you should simply memorise them.

Everything else — the non-masculine-personal plural

Feminine, neuter, and all masculine nouns that are not men. The system here is simple: the stem does not change, and there are three endings.

Neuter plurals that surprise

A few neuter nouns have a plural you would not predict, and two of them are extremely common.

Fleeting e — the disappearing vowel

Many masculine nouns have an e in the last syllable of the nominative singular that disappears when an ending is added. Since the nominative plural adds an ending, the e drops there too.

pies → psy · chłopiec → chłopcy · wróbel → wróble

talerz → talerze (keeps the e — not every e is fleeting)

The fleeting e is not predictable from the spelling. When you learn such a noun, learn its plural with it: pies — psy, not just pies.

When the plural means something else

A few nouns change meaning in the plural, and the nominative is where you see it.

Surnames in the plural

Two surnames are enough to show the rule, and it is a rule, not a list: a surname that declines like an adjective takes the masculine-personal plural of an adjective; a surname that declines like a noun takes -owie when it names a couple or a family.

Kowalski → Kowalscy (adjectival: -ski → -scy)

Nowak → Nowakowie (noun-like: -owie for a couple or family)

This is the standard Polish way of naming a couple: Maria i Jan Kowalscy, państwo Nowakowie.

Seeing the nominative inside the whole paradigm makes it easier to remember, and it shows you the forms the nominative is not. Every form below was taken from the declension table of Polish Wiktionary.

Masculine — person: student

Masculine — thing: dom

Compare the accusative: studenta but dom. That is the animal/thing split at work — and note that it does not affect the nominative at all.

Masculine in -a: kolega

Feminine: kobieta

Feminine in a soft consonant: noc

The accusative equals the nominative — widzę noc — and that is the signature of every feminine noun ending in a consonant.

Neuter: okno

Neuter in -ę: imię

The whole stem expands from imi-ę to imion-. The nominative plural imiona follows from that, and so does every other case.

An adjective always agrees with its noun in gender, number and case. In the nominative that means the adjective has five forms in the plural-and-singular system: three in the singular, two in the plural.

The masculine-personal plural: -i becomes -y, and the stem changes

This is the form learners forget, because it is the only one that looks different from the pattern. After a hard stem, -y becomes -i; after k and g it becomes -cy and -dzy; and the stem consonant shifts.

The last two do not change: tani → tani, głupi → głupi — a stem already ending in a soft consonant takes no ending at all, and the form looks like the masculine singular.

Adjectives used as nouns

Polish turns an adjective into a person-noun with no extra word — the adjective simply stands alone in the masculine-personal plural, or in the singular with a masculine ending.

Chorzy czekają na lekarza. — “the sick (people) are waiting”

Dorośli nie rozumieją. — “adults don’t understand”

Biedni i bogaci. — “the poor and the rich”

This is why dorośli (adults) is masculine-personal even when it means adults in general: the adjective keeps its masculine-personal plural.

Soft-stem adjectives and the -i / -y spelling

Polish spelling does not allow ky, gy, so adjectives whose stem ends in k or g take -i in the masculine singular and -i after softening elsewhere:

wielki, wielka, wielkie — wielcy · drogi, droga, drogie — drodzy · polski, polska, polskie — polscy

The pattern -ski → -scy is worth noticing because it is also how surnames work: Kowalski → Kowalscy.

Personal pronouns have their own nominative forms, and they carry the same masculine-personal split as nouns. In fact pronouns are where the split is easiest to see — and where it matters most, because the third person pronoun is what you use to check the gender of anything.

Everyone, nobody, somebody

The indefinite and negative pronouns behave like masculine-personal adjectives when they refer to people:

Ktoś przyszedł. · Nikt nie przyszedł. · Wszyscy przyszli.

Someone came. · Nobody came. · Everyone came.

Wszyscy is the masculine-personal form — it means “all people”. For everything else the form is wszystkie: Wszystkie dzieci przyszły, wszystkie koty.

Demonstrative and interrogative pronouns

These decline like adjectives, so their nominative has the same five shapes:

Ci ludzie · te kobiety · te dzieci · którzy studenci · które koty

these people · these women · these children · which students · which cats

Possessive pronouns

mój, twój, nasz, wasz, swój all decline like adjectives. In the nominative:

Moi rodzice · moje dzieci · nasi studenci · nasze koty

my parents · my children · our students · our cats

Moi rodzice — “parents” is masculine-personal because there is a father in it, even though mama is feminine.

Numbers are where the nominative meets the genitive, and where most learners make their first real mistake. The rule has three parts.

2, 3, 4 — the nominative zone

Up to four, the noun stays in the nominative plural. This is the one place where a number and a nominative plural sit together, so it belongs on this page.

dwa koty · dwie kobiety · dwa okna · trzy książki · cztery domy

Notice that dwa has a feminine form dwie, used with feminine nouns, and dwa covers masculine and neuter. trzy and cztery have one form for everything.

Five and above — the noun leaves the nominative

From five upward the noun goes into the genitive plural and the verb becomes singular neuter:

Pięć kotów było w ogrodzie.

There were five cats in the garden. — literally “five of cats it-was”

Pięciu studentów przyszło.

Five students came.

Pięciu is the masculine-personal form of the numeral; with women, children or things it is pięć: pięć kobiet, pięć książek.

Collective numerals

For groups of mixed gender, for children, and for nouns that only exist in the plural, Polish uses the collective numerals: dwoje, troje, czworo, pięcioro and so on. These are followed by the genitive plural.

dwoje dzieci · troje drzwi · pięcioro studentów

two children · three doors · five students (mixed group)

The reason the nominative plural matters so much is that it controls the verb. In the present tense the verb distinguishes only person and number, so the gender is invisible. In the past tense and the conditional, gender appears — and the masculine-personal split becomes visible.

* Cats do not read, but the form shows the pattern. The point is the past tense: -li only ever appears when the subject is masculine-personal.

Mixed groups

A mixed group of people takes the masculine-personal forms as soon as one man is in it — even if the group is overwhelmingly women.

Ania, Kasia i Tomek przyszli. — one man in three → -li

Ania i Kasia przyszły. — women only → -ły

Ania, Kasia i kot przyszły. — an animal does not count as personal

When the subject is a number

As the numerals section showed, a subject above four takes a singular neuter verb:

Pięć osób przyszło. · Sześć kotów spało. · Dwadzieścia lat minęło.

Five people came. · Six cats were sleeping. · Twenty years passed.

This is not an error — it is the standard agreement for a numeral subject. Pięć osób przyszły would be wrong.

Agreement with państwo and polite forms

Polish has no single polite “you”. It uses pan (to a man), pani (to a woman), państwo (to a mixed group), panowie (to men), panie (to women).

Pan czyta. · Pani czyta. · Państwo czytają.

You are reading. (to a man / to a woman / to a group)

Adjectives agree too

An adjective in the nominative must match the noun in gender and number. This is where the five-form table from the adjectives section does its work:

dobry student · dobra studentka · dobre dziecko

dobrzy studenci · dobre studentki · dobre koty

These are the mistakes that actually get made — by learners and, in the colloquial variants, by native speakers too.

Trap 1 · to jest vs jestem …

The single most common error. After być describing a role, the noun is instrumental; after to identifying a thing, it is nominative.

Jestem nauczycielem. ✓ — role

To jest nauczyciel. ✓ — identification

Jestem nauczyciel. ✗

The exception: a bare adjective after być stays nominative and agrees with the subject — Jestem zmęczony, not zmęczonym. Once the adjective has a noun to agree with, it follows that noun: Jestem dobrym studentem.

Trap 2 · to jest vs to są

English says “this is” for one thing and “these are” for several, and Polish does the same — but Polish is stricter, because to is a full subject.

To jest książka. — one

To są książki. — several

To są moi rodzice. — several people

Trap 3 · The nominative after to stays nominative — even in a list

To jest kot i pies. — a compound subject: the verb can stay singular

To są kot i pies. — also correct, and more careful

With a compound subject, the standard rule prefers the plural verb when the parts are concrete things, as the University of Warsaw language clinic puts it: W łazience są wanna i umywalka, not jest wanna i umywalka.

Trap 4 · Nominative or vocative?

When you address someone directly, Polish uses the vocative, not the nominative. This is the one place where the nominative is simply wrong.

Marek czyta. — nominative: he is the subject

Marku, czytaj! — vocative: addressing him

Panie Marku, … · Pani Anno, … · Kolego, …

With first names and common nouns the vocative is different from the nominative; with many surnames and with most nouns ending in a consonant it looks identical, which is why learners often do not notice the difference until they meet a name like Marku or Anno.

Trap 5 · ludzie and dzieci

Two plurals that do not look like their singulars at all, and both are extremely common.

człowiek → ludzie (masculine-personal: ludzie przyszli)

dziecko → dzieci (non-personal: dzieci przyszły)

Trap 6 · państwo — singular form, plural meaning

Państwo looks like a neuter singular noun and literally means “state”, but as a polite “you” it is masculine-personal plural: Państwo są zmęczeni, Państwo przyszli.

So państwo has two lives: “the state” (neuter singular — państwo jest duże) and “you (plural, polite)” (masculine-personal — państwo są zmęczeni).

Trap 7 · Country names and Niemcy

Plural country names take plural verbs, and Niemcy is ambiguous between “Germany” and “Germans”:

Niemcy są dużym krajem. — Germany is a big country: non-personal

Niemcy przyjechali. — the Germans arrived: masculine-personal

Trap 8 · The nominative after prepositions — it does not happen

Every Polish preposition governs a case, and no preposition ever governs the nominative. If you see a preposition, the word after it is not nominative — it is genitive, dative, accusative, instrumental or locative.

do domu · w domu · z domem · na dom

This is a useful sanity check: if you have written a preposition and then a nominative, one of the two is wrong.

Trap 9 · Colloquial forms you will hear

Living Polish has variants that the standard does not accept. Knowing them helps you understand, but do not produce them in writing.

Poszłem and wzięłem are widely heard and widely condemned; they are the Polish equivalent of “I seen it”. Use poszedłem, wziąłem.

The ending map

The five rules that cover most real sentences

1. Every dictionary word is a nominative. Learn the noun with its gender: ta noc, not noc.
2. Subject = nominative. The verb agrees with it, and in the past tense reveals its gender: byli vs były.
3. to + nominative, być + instrumental. To jest nauczyciel but Jestem nauczycielem.
4. The plural splits by men. One man in the group → -i/-y/-owie and byli. No man → -y/-i/-e and były.
5. No preposition takes the nominative. Ever.

Plurals worth memorising

człowiek → ludzie · brat → bracia · ksiądz → księża · książę → książęta · dziecko → dzieci

oko → oczy · ucho → uszy · ręka → ręce · rok → lata

mężczyzna → mężczyźni · sędzia → sędziowie · poeta → poeci · gość → goście

Say it out loud, ten times

To jest nauczyciel. · Jestem nauczycielem. · Studenci przyszli. · Studentki przyszły. · Dzieci przyszły. · Ludzie przyszli.

Ci ludzie · te kobiety · te koty · moi rodzice · moje dzieci · państwo są zmęczeni
