Dopełniacz (Genitive)

The 'of / no / from' case: absence, possession, quantity

Grammar A1

What the Genitive does

The Genitive shows absence, possession, or amount. It answers kogo? czego? (of whom? of what?).

Absence: nie ma czasu - there's no time
Possession: samochód brata - brother's car
Quantity: szklanka wody - a glass of water

Nie ma mleka.

There's no milk.

To jest książka Anny.

This is Anna's book.

Signals that trigger Genitive

Memorize these triggers and half the work is done.

nie ma (there isn't) + Gen: nie ma czasu
Negated verbs: nie mam samochodu, nie widzę Anny
Prepositions: z, do, od, dla, bez, u, obok
Numbers 5+ and dużo/mało/trochę/ile: dużo ludzi

The negation rule is crucial: in standard Polish a direct object that would be Accusative normally changes to Genitive when the verb is negated. Mam czas → Nie mam czasu. This applies to the direct object - a complement already required in another case normally stays in that case: Pomagam mamie → Nie pomagam mamie.

Jadę do Warszawy.

I'm going to Warsaw.

Kupuję kawę bez cukru.

I'm buying coffee without sugar.

Masculine singular: -a or -u

The trickiest part of the Genitive - two possible endings.

Group	Ending	Example
People & animals	-a	brat → brata, kot → kota
Tools, body parts, months	-a	nóż → noża, palec → palca, styczeń → stycznia
Abstract & uncountable	-u	czas → czasu, cukier → cukru, sport → sportu

Rule of thumb: -a for living things, tools, body parts, months, and currencies. -u for abstracts, liquids, materials, and feelings. Some common words break the pattern (chleb → chleba, dom → domu) - just memorize them.

Nie ma brata.

Brother isn't here.

Nie ma cukru.

There's no sugar.

Feminine singular: -y or -i

Much simpler than masculine - just watch the last consonant.

Group	Ending	Example
Default	-y	kawa → kawy, kobieta → kobiety
After k, g	-i	książka → książki, noga → nogi
After soft consonant	-i	ulica → ulicy, kuchnia → kuchni

If the word ends in -ka, -ga, use -i. If it ends in a soft consonant (like -nia, -cia), you also usually get -i. Everything else takes -y.

Szklanka wody, proszę.

A glass of water, please.

Nie ma książki.

The book isn't here.

Neuter singular: -a

Neuter nouns almost always take -a in the Genitive.

Group	Ending	Example
-o → -a	okno → okna	Nie ma okna.
-e → -a	mieszkanie → mieszkania	Szukam mieszkania.
-ę → -ęcia / -enia	dziecko → dziecka	Nie mamy dziecka.

'Dziecko' is neuter and follows the -o → -a rule in the singular. Its plural is famously irregular (dzieci).

Nie ma piwa.

There's no beer.

Kawa bez mleka.

Coffee without milk.

Plural Genitive: the trickiest form

Plural Genitive endings depend on the gender and are notoriously varied.

Group	Ending	Example
Masculine personal	-ów	studentów, Polaków, panów
Masc. non-personal	-ów / -y / -i	kotów, samochodów, dni
Feminine	zero ending	kobiet, książek, sióstr
Neuter	zero ending	okien, mieszkań, dzieci

Feminine and neuter often drop the final vowel, sometimes inserting an -e-: książka → książek, okno → okien. This is called the fleeting vowel.

Pięciu studentów jest w klasie.

Five students are in the class.

Dużo książek na stole.

Lots of books on the table.

Watch out: negation flips Accusative to Genitive

This is the #1 mistake foreigners make in Polish.

Mam kawę. (Acc) → Nie mam kawy. (Gen)
Widzę Annę. (Acc) → Nie widzę Anny. (Gen)
Lubię pizzę. (Acc) → Nie lubię pizzy. (Gen)

Any verb whose direct object was Accusative switches that object to Genitive under negation. Treat it as the standard rule - it holds for the direct object of a negated verb. It does not touch objects that were already in another case (Pomagam mamie → Nie pomagam mamie, still Dative).

Nie znam tego człowieka.

I don't know this person.

Nie piję kawy.

I don't drink coffee.
