Nominative case
A1 Mianownik 4 / 52
In short
Polish nouns, adjectives and pronouns change their endings depending on their role in the sentence - this is called case. The nominative (Polish mianownik) is the base, dictionary form: it is the case of the subject, the person or thing doing the action. It answers the questions kto? (who?) and co? (what?). Every word you meet in a dictionary is given in the nominative, so this is where learning a noun begins.
The rule
The nominative marks the subject of a clause - the doer of the verb - and it is also the form used after the linking verb być (to be) in simple identifying statements at the very start of learning (To jest kot - This is a cat). It is the citation form: when you look a word up, you find its nominative singular.
What the nominative does
- Names the subject: Kot śpi. (The cat sleeps.) - kot does the sleeping, so it is nominative.
- Answers kto? / co?: ask “who or what is doing this?” and the answer is nominative. Kto to jest? To jest Anna. (Who is this? This is Anna.)
- Follows “to (jest)”: in the pattern To jest / To są + noun, the noun stays nominative: To jest dom (This is a house), To są koty (These are cats).
Why endings matter
Because the subject is marked by case, Polish does not need a fixed word order the way English does. Kot widzi psa and Psa widzi kot both mean “The cat sees the dog” - the endings (kot = nominative subject, psa = accusative object), not the position, tell you who does what. Learning the nominative first gives you the anchor against which all the other cases are contrasted.
Gender is read off the nominative
The nominative singular ending is what tells you a noun’s gender, which then controls agreement everywhere else:
- Masculine: usually ends in a consonant - kot (cat), dom (house), student (student).
- Feminine: usually ends in -a - kobieta (woman), książka (book), lampa (lamp).
- Neuter: usually ends in -o, -e, -ę, -um - okno (window), morze (sea), imię (name), muzeum (museum).
Forms & patterns
The nominative is the unmarked, base form, so there is little to “build” here - the point is to recognise the typical endings by gender, singular and plural.
Nominative singular by gender
| Gender | Typical ending | Examples (Nom. sg.) |
|---|---|---|
| masculine | consonant | student, kot, dom, nauczyciel |
| feminine | -a (rarely -i, or consonant) | kobieta, książka, pani, noc |
| neuter | -o / -e / -ę / -um | okno, pole, imię, centrum |
Nominative plural
The plural ending depends on gender and, for masculine nouns, on whether the noun is personal masculine (a male human = męskoosobowy / virile) or not.
| Group | Sg. -> Pl. ending | Example |
|---|---|---|
| masculine personal (male humans) | -i / -y / -e (+ softening) | student -> studenci, Polak -> Polacy, nauczyciel -> nauczyciele |
| masculine non-personal (things, animals) | -y / -i / -e | kot -> koty, pies -> psy, pokój -> pokoje |
| feminine | -y / -i / -e | kobieta -> kobiety, książka -> książki, ulica -> ulice |
| neuter | -a | okno -> okna, pole -> pola, muzeum -> muzea |
Consonant alternations in the masculine personal plural
Forming the plural of male-human nouns often triggers a softening of the final consonant - a key A1 pattern to recognise:
| Sg. ends in | Alternation | Example |
|---|---|---|
| -t | t -> ci | student -> studenci |
| -k | k -> cy | Polak -> Polacy |
| -g | g -> dzy | kolega -> koledzy |
| -r | r -> rzy | aktor -> aktorzy |
| -ch | ch -> si | Włoch -> Włosi |
The demonstrative “to” and the pattern To jest / To są
| Number | Pattern | Example |
|---|---|---|
| singular | To jest + Nom. sg. | To jest książka. (This is a book.) |
| plural | To są + Nom. pl. | To są książki. (These are books.) |
Note that to here is invariable - it does not agree with the noun; only the following noun and verb (jest / są) change.
Examples
| Polski | English |
|---|---|
| Kot śpi na kanapie. | The cat is sleeping on the sofa. |
| To jest mój dom. | This is my house. |
| Anna jest nauczycielką. | Anna is a teacher. |
| Studenci czytają książki. | The students are reading books. |
| Gdzie jest twoja siostra? | Where is your sister? |
| Dzieci bawią się w parku. | The children are playing in the park. |
| To są nowe okna. | These are new windows. |
| Pies i kot mieszkają razem. | The dog and the cat live together. |
| Kto to jest? To jest pan Kowalski. | Who is this? This is Mr Kowalski. |
| Moi koledzy są mili. | My friends (male) are nice. |
Common mistakes
- To jest kota -> To jest kot - after to jest the noun stays nominative (kot), not accusative (kota).
- studentzy -> studenci - the male-human plural of student softens t -> ci, it is not a simple added -y.
- Polakowie -> Polacy - Polak takes -cy with k -> c softening, not the ending -owie here.
- dwa okno -> dwa okna - neuter plural of okno is okna; the noun must be plural, not left in the singular.
- ta dom -> ten dom - dom ends in a consonant, so it is masculine and takes ten, not the feminine ta.
- Kot widzi pies meant as “the cat sees the dog” -> Kot widzi psa - only the subject kot stays nominative; the object pies must take the accusative (psa). Polish reads the roles off the endings, not off English word order.
Tips
- Learn every noun in its nominative singular - that is the dictionary form and it reveals the gender at a glance.
- Quick gender test: ends in a consonant -> masculine; ends in -a -> feminine; ends in -o/-e/-ę -> neuter (a handful of exceptions exist, e.g. mężczyzna “man” is masculine despite -a).
- Ask kto? co? (“who? what?”) of the verb - whatever answers is your nominative subject.
- The nominative is your baseline: every other case is easier to learn as “the nominative, but changed to show a different role.”
- Watch for softening in male-human plurals (Polak -> Polacy, student -> studenci); it is regular once you spot which consonant changes.
- Remember that to in to jest / to są never changes - only the noun after it moves between singular and plural.
