Serbian has several ways to count people and things because a number can describe not only quantity but also the composition of a group. Двоје, троје, четворо are collective numerals for mixed-gender groups and young beings; двојица, тројица, четворица explicitly count males; agreeing forms such as двоја врата count sets of nouns that exist only in the plural. These systems overlap in number but not in meaning.
Collective numerals: dvoje, troje, četvoro
The basic series is двоје, троје, четворо, петоро, шесторо, седморо, осморо, деветоро, десеторо. Larger forms continue the pattern, and in compounds the final component is collective: двадесет петоро студената.
Use collective numerals mainly with:
- nouns for children or young animals: двоје деце, троје јагњади;
- a group explicitly containing male and female people: четворо студената;
- a standalone mixed group: њих двоје, вас троје.
The following noun is a partitive complement, normally in genitive plural or the appropriate genitive collective form.
Троје деце се игра испред зграде док их отац посматра са терасе.
Three children are playing in front of the building while their father watches them from the terrace.
У финале је ушло четворо студената: две студенткиње и два студента.
Four students reached the final: two women and two men.
На фарми се током ноћи родило двоје телади.
Two calves were born on the farm during the night.
Водитељ је рекао: „У програму учествује двадесет петоро студената.“
The host said, ‘Twenty-five students of mixed genders are taking part in the program.’
The collective form does not say which members are male or female individually. It packages them as one mixed or age-defined set. English three students leaves group composition unmarked; Serbian can choose to encode it.
All-male and all-female groups
For groups consisting only of male persons, Serbian has masculine-person numeral nouns: двојица, тројица, четворица, петорица and so on. From four upward, these forms typically end in -орица. Their noun complement is genitive plural.
Тројица мајстора су стигла рано и одмах почела да раде.
Three male tradespeople arrived early and immediately started working.
Semantic masculine-plural predicate agreement is also standard:
Тројица мајстора су стигли рано и одмах почели да раде.
Three male tradespeople arrived early and immediately started working.
For an all-female group, use an ordinary cardinal with a feminine noun: две лекарке, три ученице, четири колегинице.
Две лекарке и тројица техничара дежурају вечерас.
Two female doctors and three male technicians are on duty tonight.
This makes a useful four-way contrast:
| Group | Natural form |
|---|---|
| two male students | два студента / двојица студената |
| two female students | две студенткиње |
| one male and one female student | двоје студената |
| two children | двоје деце |
Ordinary два студента counts two grammatically masculine students without highlighting group composition. Двојица студената explicitly presents them as male persons.
Oboje, obojica, oba, obe
English both splits into several Serbian forms:
- обоје: a mixed pair, two children/young beings, or two abstract alternatives;
- обојица: two male persons;
- оба: both masculine or neuter nouns;
- обе: both feminine nouns.
Милица и Ненад су из Ниша; обоје сада раде у Београду.
Milica and Nenad are from Niš; both now work in Belgrade.
Ненад и Марко су из Ниша; обојица сада раде у Београду.
Nenad and Marko are from Niš; both men now work in Belgrade.
Оба рачуна су плаћена, а обе потврде су сачуване.
Both bills have been paid, and both confirmations have been saved.
Обоје can also mean “both things/both alternatives.”
Можемо да кренемо возом или аутобусом; обоје ми одговара.
We can go by train or bus; both options work for me.
Here neuter singular одговара reflects an abstract “both alternatives” reading. With a mixed pair of people, semantic plural is common, as in обоје раде above.
Predicate agreement
With a collective numeral plus an overt noun, neuter singular is the dependable formal pattern: троје деце је дошло, четворо студената је изабрано. Semantic plural is also found, especially when the people are prominent as individuals. With standalone обоје referring to a man and a woman, plural predicates are particularly natural.
Двоје нових колега је стигло јуче, а обоје су већ упознали тим.
Two new colleagues, one woman and one man, arrived yesterday, and both have already met the team.
The first clause presents a quantified group and uses neuter singular је стигло. The second treats the two people as discourse participants and uses plural су упознали. This is a shift in construal, not random agreement.
Masculine-person numeral nouns allow neuter-plural formal agreement and masculine-plural semantic agreement, as the paired тројица мајстора examples showed.
Declension in current Serbian
Masculine-person numerals decline like feminine singular nouns, while the counted noun stays genitive plural:
| Case | Form with “three colleagues” |
|---|---|
| Nominative | тројица колега |
| Genitive | тројице колега |
| Dative/locative | тројици колега |
| Accusative | тројицу колега |
| Instrumental | тројицом колега |
Разговарала сам са тројицом колега, а касније сам позвала још двојицу.
I spoke with three male colleagues and later called two more.
Collective двоје, троје, четворо are usually left unchanged in contemporary usage, including after prepositions: са троје деце. Declined forms above two are now marginal. Обома and двома survive more readily, especially standalone or with a personal pronoun, in careful prose.
Поклон је намењен обома, а поруку сам послао њима двома.
The gift is intended for both of them, and I sent the message to the two of them. (careful style)
Do not manufacture rare paradigms in everyday speech. The numeral declension page explains when inflection is productive and when restructuring is more natural.
Plural-only nouns: dvoja vrata, dvoje makaze
Nouns such as врата “door,” кола “car,” маказе “scissors,” and панталоне “trousers” are pluralia tantum: their ordinary lexical form is plural. To count sets, Serbian uses numeral adjectives that agree with their grammatical gender.
| Noun gender | One set | Two sets | Three sets |
|---|---|---|---|
| Neuter plural | једна врата | двоја врата | троја врата |
| Neuter plural | једна кола | двоја кола | троја кола |
| Feminine plural | једне маказе | двоје маказе | троје маказе |
| Feminine plural | једне панталоне | двоје панталоне | троје панталоне |
Although двоје маказе looks like collective двоје, it is an agreeing feminine-plural numeral adjective here. With neuter врата, the ending is -а: двоја врата.
За нову канцеларију купили смо двоја врата и троје маказе.
For the new office we bought two doors and three pairs of scissors.
For items whose singular exists but which naturally come in pairs, пар + genitive plural is often clearer: један пар ципела, два пара чарапа.
Понела је два пара чарапа и једне резервне панталоне.
She packed two pairs of socks and one spare pair of trousers.
In informal speech, пар can also mean “a few,” as in пар дана (informal). In precise counting it means a pair and behaves as a noun: један пар чарапа, два пара чарапа.
A practical mixed-group example
Двоје деце, од осам и десет година, платило је 2. маја по триста динара за радионицу.
Two children, aged eight and ten, each paid three hundred dinars for the workshop on May 2.
This sentence combines collective двоје деце, cardinal ages, an ordinal date written with a period, and a price. Spoken aloud, the opening is двоје деце, not два деца, and the date is другог маја.

Common Mistakes
Using an all-male numeral for a mixed group
❌ На списку пише: „Тројица студената — Ана, Милица и Ненад.“
Incorrect—тројица denotes three males, not a mixed group containing two women and one man.
✅ На списку пише: „Троје студената — Ана, Милица и Ненад.“
The list says: ‘Three students — Ana, Milica, and Nenad.’
Using oboje for two men
❌ Милош и Иван су стигли; обоје су лекари.
Incorrect for two men—use masculine-person обојица.
✅ Милош и Иван су стигли; обојица су лекари.
Miloš and Ivan have arrived; both are doctors.
Using a collective numeral for an all-female group
❌ Троје студенткиња је добило награду.
Incorrect for three women—use the ordinary feminine cardinal phrase три студенткиње.
✅ Три студенткиње су добиле награду.
Three female students received an award.
Failing to agree the numeral adjective with vrata
❌ Ормар има двоје врата.
Incorrect—врата is neuter plural, so the agreeing numeral adjective is двоја.
✅ Ормар има двоја врата.
The wardrobe has two doors.
Putting a nominative noun after a collective numeral
❌ У ходнику чека троје студенти.
Incorrect—collective троје takes the partitive complement студената.
✅ У ходнику чека троје студената.
A mixed group of three students is waiting in the hallway.
Key Takeaways
- Двоје/троје count mixed groups and young beings; the complement is genitive.
- Двојица/тројица explicitly count male persons and decline like nouns.
- All-female groups take ordinary feminine cardinal phrases.
- Обоје, обојица, оба, обе divide “both” by group composition and noun gender.
- Plural-only nouns take agreeing numeral adjectives: двоја врата, двоје маказе; ordinary paired items often use пар + genitive plural.
