Clause Relations and Punctuation

Level 6Sounds Like veznici i interpunkciǰa u složenoǰ rečenici

In standard Serbian, punctuation is governed strictly by grammatical and logical relationships, not by breath or pauses in speech. Whether a comma is mandatory, forbidden, or optional depends directly on clause coordination (adversative, copulative, disjunctive), clause hierarchy (inversion, restrictive vs. non-restrictive), and conjunction classification.

How It Works

According to the official orthographic standard (Pravopis srpskoga jezika), punctuation in compound and complex sentences (сложена реченица) marks syntactic boundaries rather than arbitrary breathing pauses.

1. Coordinating Relations (Напоредни односи)
• Adversative clauses (супротне реченице): Generally require a comma before the conjunction: а, али, већ, него, но (e.g., Ја радим, а он спава). However, when two contrasting predicates form an inseparable, fused conceptual and rhythmic unit, the comma is omitted (e.g., Слуша али не чује; Гледа а не види).
• Copulative, Disjunctive, and Gradational clauses (саставне, раставне и градационе реченице): A single copulative connector и or disjunctive connector или linking integrated actions takes no comma. When coordinating conjunctions are repeated correlatively (и... и..., или... или..., ни... ни..., нити... нити...), a comma is normally required before the second element when separating distinct, extended clauses or contrasting predications pronounced with a pause (e.g., Или ћеш радити, или ћеш отићи). However, when short correlative predicate pairs are tightly fused into a single rhythmic and semantic unit, the comma is standardly omitted (e.g., Нити говори нити слуша; Није ни јео ни пио). The connectors па and те omit commas only in seamless, immediate temporal sequences of actions (e.g., Устаде па оде); whenever they express a consequence or conclusive relation, standard punctuation requires a comma (e.g., Није учио, па је пао на испиту). In gradational clauses, correlative constructions like не само што... него/већ и... standardly take no comma before the second part because it marks a cumulative gradation rather than an adversative split; conversely, gradational clauses introduced by а камоли, а некмоли, and а поготово obligatorily require a preceding comma (e.g., Није могао да хода, а камоли да трчи).
• Exclusionary and Conclusive clauses (искључне и закључне реченице): Exclusionary clauses always require a comma before connectors such as само, само што, једино, једино што. Conclusive clauses require a comma at the clause boundary; conclusive connectives (such as the modal particle дакле, the pronominal adverbs зато, стога, or the phrasal connective према томе) can appear internally within the second clause, with the comma positioned at the boundary between clauses (e.g., Није се припремио, пао је стога на испиту).

2. Subordinating Relations (Зависни односи)
• Normal Order (Matrix + Dependent): Subordinate clauses following the main clause generally take no comma when tightly integrated into the sentence. This applies to complement clauses (e.g., Знао сам да ће доћи) and unmarked adverbial clauses (e.g., Отићи ћемо кући када завршимо посао; Остаћемо у соби ако падне киша). Notice the contrast in causal expressions: јер standardly requires a preceding comma (e.g., Није дошао, јер је био болестан), whereas зато што in post-position is tightly integrated and takes no comma (e.g., Није дошао зато што је био болестан).
• Inversion (инверзија): When an adverbial clause (temporal, conditional, causal, concessive) precedes the main clause, a separating comma is strictly obligatory (e.g., Када завршимо посао, отићи ћемо кући; Ако падне киша, остаћемо у соби). However, this rule does not apply to preposed nominal clauses: preposed subject clauses (e.g., Ко рано рани две среће граби) and tightly linked preposed object clauses (e.g., Шта тражи то ће и наћи) generally omit the comma.
• Embedded and Relative clauses (уметање и односне реченице): Non-restrictive, appositive clauses are enclosed in commas (e.g., Мој отац, који живи у Нишу, сутра долази). Essential, restrictive relative clauses embedded directly or postposed take no commas (e.g., Људи који раде овде су веома љубазни).

3. Conjunction-Specific Mechanics
• No comma after the conjunction: Unlike English However, ..., Serbian coordinating conjunctions are never followed immediately by a comma (write Али он није дошао, never Али, он није дошао).
• Comparative vs. Adversative него: When него introduces a comparative clause of degree following a comparative adjective, it takes no comma (e.g., Бољи је него што сам мислио). It takes a comma only when used adversatively in contrast (не ... него).

Examples (5)

  1. Када будемо завршили све обавезе, отићи ћемо на одмор, али још не знамо тачно где.

    When we finish all our obligations, we will go on vacation, but we still do not know exactly where.

    Word by Word: When we-will-be finished all obligations, we-will-go on vacation, but still not we-know exactly where.

    Features an inverted temporal clause requiring a comma after 'обавезе', followed by an adversative clause requiring a comma before 'али'.

  2. Сви грађани који имају важећу личну карту могу да гласају.

    All citizens who hold a valid ID card can vote.

    Word by Word: All citizens who have valid personal card can that vote.

    A restrictive relative clause specifying which citizens are meant; it is structurally bound to the noun phrase and takes no comma.

  3. Мој комшија Јован, који ради у градској болници, помогао ми је јуче.

    My neighbor Jovan, who works at the city hospital, helped me yesterday.

    Word by Word: My neighbor Jovan, who works in city hospital, helped to-me is yesterday.

    A non-restrictive, appositive relative clause adding descriptive detail about a known person; it must be framed by commas on both sides.

  4. Он је читао књигу и његова сестра је слушала музику.

    He was reading a book and his sister was listening to music.

    Word by Word: He is read book and his sister is listened music.

    Copulative coordination with single 'и' linking two parallel clauses; in standard Serbian, no comma precedes 'и'.

  5. Овај задатак је много тежи него што смо очекивали.

    This task is much harder than we expected.

    Word by Word: This task is much harder than what we-expected.

    When 'него што' introduces a comparative clause of degree following a comparative adjective, no comma is used.

Common Mistakes

  • Placing a comma before complement clauses or postposed adverbial clauses.

    Рекао ми је, да ће отићи на море, када заврши испите.
    Рекао ми је да ће отићи на море када заврши испите.

    Unlike Russian or German, Serbian uses no comma before tightly bound complement clauses with 'да', nor before postposed adverbial clauses in normal order ('када заврши испите').

  • Omitting the mandatory comma after an inverted adverbial clause, or mistakenly putting one after a preposed subject clause.

    Ако сутра буде лепо време ићи ћемо на излет, док ко рано рани, две среће граби.
    Ако сутра буде лепо време, ићи ћемо на излет, док ко рано рани две среће граби.

    When an adverbial clause (temporal, conditional, causal, concessive) precedes the main clause, a comma is strictly obligatory. In contrast, preposed subject or tightly linked object clauses generally take no comma.

  • Placing an immediate comma after sentence-initial conjunctions by transferring English habits.

    Али, ми то никада нисмо чули.
    Али ми то никада нисмо чули.

    Serbian coordinating conjunctions like 'али', 'а', and 'па' are unstressed connective elements and are never followed immediately by a comma.
