Plural of nouns and adjectives

First of all, you should know that all plural nouns – we share into two groups in Polish:

Group 1: a group of males (only men/ boys, don’t mix it with masculine nouns) or a group where at least one male in present, e.g. students, doctors, Polish people.

But for example: sok (juice) although is a masculine word- it is not a man, so it does not belong to this group)!

Group 2: everything else: women, animals, objects, food etc.

Yes, I know girls, it is a discrimination!:D

Here I will teach you how to make a plural for the second group. To make plural for the first group is a bit more complicated and we will worry about it later.:)

In English, we usually add '–s' to form a plural, in Polish we have 4 possible endings:

1) – a, when the words is neutral (ends with –o, -e, -um):

piwo- piwa (a beer- beers)

okno –okna (a window- windows)

centrum- centra (a center- centers)

2) – i, when the last consonant of the word is –k or –g:

sok- soki (juice- juices)

mąka- mąki (flour- flours) 

3) –e, after almost all these "funny":) Polish letters which you can NOT find in English language: ś (also si), ć (also ci), ń (also ni), ź (also zi), ż, sz, cz, rz + c,l,j

noc- noce (a night- nights)

koń- konie (a hourse- hourses)

4) – y (for all other words)

All adjectives which describe the group 2 (women, animals, objects, food etc.) end with –e:

ładne dziewczyny –pretty girls

wysokie budynki- high buildings

More examples for all 4 endings:

rachunek - rachunki

kawa- kawy

wino- wina

masło- masła

chleb- chleby

brzoskwinia- brzoskwinie
