Overview

Plural endings depend on gender: masculine usually takes -и, feminine -а changes to -е, and neuter -о/-е to -а.

This lesson covers the nominative plural (subject form); other cases have their own plural endings.

Masculine plural: -и, and the -ов-/-ев- infix

Most masculine nouns simply add -и to the consonant-final singular: студент → студенти, пријатељ (friend) → пријатељи. Nothing else changes.

Many monosyllabic masculine nouns - one syllable in the nominative singular - insert -ов- or -ев- before that same -и. After a hard final consonant the infix is -ов-: град (city) → градови, мост (bridge) → мостови. After a soft/palatal final consonant (ч, ж, ш, ђ, ћ, џ, љ, њ, ј, ц) the infix is -ев- instead: кључ (key) → кључеви, нож (knife) → ножеви. Some frequent one-syllable nouns take no infix and simply add -и: зуб (tooth) → зуби, прст (finger) → прсти, дан (day) → дани - learn these separately.

Feminine and neuter plural

Feminine nouns ending in -а swap it for -е: жена (woman) → жене, књига (book) → књиге. Feminine nouns ending in a consonant instead - the exception class from the lesson on noun gender, like ноћ - take -и: ноћ (night) → ноћи.

Neuter nouns swap their singular -о or -е for -а: село (village) → села, поље (field) → поља. This covers most neuter nouns cleanly, but a small class of nouns ending in -е inserts an -ен- infix instead of a plain swap - име (name) → имена, време (time) → времена - so it isn't quite as exception-free as it looks.

Extra stem changes in some plurals

Some masculine nouns change their stem before -и. Learn common forms such as ђак → ђаци and бубрег → бубрези as vocabulary.

Some masculine nouns have a vowel that disappears in the plural: момак → момци, пас → пси. Learn common forms as vocabulary; detailed sound-change rules come later.

Irregular plurals to memorize

A few common nouns have irregular plural forms that are best learned as vocabulary: човек → људи, око → очи, ухо → уши, дете → деца and брат → браћа.

For now, learn дете → деца and брат → браћа as irregular plural forms. Their agreement patterns are covered later.

Monosyllabic masculine noun град takes the -ов- infix before -и.

Ključevi su na stolu.

The keys are on the table.

Soft-stem monosyllabic noun кључ takes -ев-, not -ов-.

Žene rade u školi.

The women work at the school.

The feminine plural is жене.

Sela su mala, ali lepa.

The villages are small, but beautiful.

Neuter noun: -о becomes -а - село → села.

Momci pevaju pesmu.

The young men are singing a song.

The plural of момак is момци. Learn this common form as a word.

Ljudi vole muziku.

People love music.

Човек has a fully irregular plural, људи - no rule produces it.

Oči su joj plave.

Her eyes are blue.

The plural of око is очи. Learn this irregular form as vocabulary.

Čaše su čiste.

Feminine -а noun swaps the ending for -е: чаша → чаше - the easiest plural pattern.

Tanjiri su na stolu.

The plates are on the table.

Тањир is a consonant-final masculine noun of more than one syllable, so it just adds -и - no infix needed.

Noževi su oštri.

The knives are sharp.

Soft-stem monosyllabic noun нож takes -ев-, the same pattern as кључеви above.

Compared with…

English marks almost every plural with one ending, -s (or -es), regardless of gender - a category English nouns don't even have. Serbian instead picks the ending from gender, and layers sound changes (sibilarization, the fleeting а) that English's plain -s never triggers. The one genuine bridge is irregular plurals: English already has child→children and man→men, so a plural that must be memorized rather than derived is a familiar idea - only the words and their number (five, not two or three) differ.

Serbian

Ovo dete je moje. Ova deca su moja.

Дете→деца mirrors English child→children - both irregular, memorized rather than derived.

English

This child is mine. These children are mine.

Common mistakes

Wrong

To su mosti.

Right

To su mostovi.

Мост is a monosyllabic masculine noun and needs the -ов- infix before the plural -и: мостови, not *мости.

Wrong

To su ključi.

Right

To su ključevi.

After a soft/palatal final consonant like ч, the infix is -ев-, not plain -и: кључеви, not *кључи.

Wrong

To su kuća.

Right

To su kuće.

Feminine -а nouns swap the ending to -е in the plural - куће, not the unchanged singular кућа.

Wrong

To su čoveci.

Right

To su ljudi.

Човек has a fully suppletive plural, људи - never a regularized *човеци.

Tips & exceptions

Tips

Predict the plural ending from the gender you already learned in the lesson on noun gender: consonant-final masculine → -и (or -ови/-еви for many one-syllable nouns), -а-feminine → -е, -о/-е-neuter → -а.
Many one-syllable masculine nouns add -ов-/-ев- before -и; learn the frequent forms as chunks. Some common nouns add only -и, such as зуб → зуби, прст → прсти and дан → дани.
The five irregular plurals - човек→људи, дете→деца, брат→браћа, око→очи, ухо→уши - cannot be derived from any rule; learn them as fixed vocabulary pairs, the same way you memorize an English irregular plural like child→children.

Exceptions

Some masculine nouns change their stem in the plural. Learn common forms such as ђак → ђаци and бубрег → бубрези as vocabulary.
Not every one-syllable masculine noun takes -ов-/-ев-. Several frequent ones add plain -и: зуб (tooth) → зуби, прст (finger) → прсти, дан (day) → дани. Learn them as individual words, the way you learn век → векови.
Деца and браћа are irregular plural forms. Learn them with their singular forms; agreement is covered later.
The plural forms очи and уши are irregular. Learn them as vocabulary.

Summary

Masculine nouns usually add -и, with -ов-/-ев- in many one-syllable words; feminine nouns ending in -а change it to -е, and neuter nouns ending in -о/-е change it to -а. Learn common exceptions and stem changes as vocabulary: зуби, ђаци, момци, људи, очи, уши, деца and браћа.
