A subordinate clause functions inside or alongside another clause: as the content of a verb, a modifier of a noun, or an adverbial of time, cause, condition, purpose, and similar relations. Serbian uses finite markers such as да, који, што, кад(а), јер, ако. Rich case and flexible order do not remove hierarchy: each clause has its own predicate, arguments, and clitic domain.
Four high-value clause families
| Marker | Typical relation | Example frame |
|---|---|---|
| да | content, command, desire, purpose | Желим [да дођеш]. |
| који | relative modifier with an internal case role | књига [коју читам] |
| што | content/cause or relative, depending on structure | Драго ми је [што си ту]. |
| кад(а) | time; embedded “when” | Јави се [кад стигнеш]. |
Надам се да ћемо завршити пре ручка.
I hope that we'll finish before lunch.
Пронашла сам документ који си јуче тражио.
I found the document that you were looking for yesterday. (female speaker)
Драго ми је што сте прихватили позив.
I'm glad that you accepted the invitation.
Позваћу те кад стигнем у хотел.
I'll call you when I arrive at the hotel.
The marker does not have one English translation. Да can correspond to that, an infinitival complement, or a purpose clause; што can mean that/because or introduce a relative strategy.
Complement clauses are selected
The main predicate determines what kind of complement is licensed. Знати selects factual да or an embedded question; желети selects desired да + present or a same-subject infinitive.
Знам да је Ана већ стигла.
I know that Ana has already arrived.
Не знам да ли је Ана већ стигла.
I don't know whether Ana has already arrived.
Желим да останем још један дан.
I want to stay one more day.
The да clause has a finite present form останем whose interpretation depends on the selecting verb. Serbian also permits Желим остати, especially in styles and regions favoring the infinitive; neither pattern is universally wrong.
Relative clauses attach to noun phrases
Позвала сам преводиоца који ради у нашој канцеларији.
I called the translator who works in our office. (female speaker)
The bracketed structure is [преводиоца [који ради...]]. Main-clause accusative преводиоца does not force the relative pronoun's case: који is nominative because it is subject of ради.
Позвала сам преводиоца којем верујемо.
I called the translator whom we trust. (female speaker)
Here којем is dative because веровати governs dative. Hierarchy, not adjacency, assigns the role.
Adverbial clauses relate events
Time, cause, condition, concession, and purpose clauses specify how two situations relate.
Кад завршиш проверу, јави ми да ли је све у реду.
When you finish the check, let me know whether everything is all right.
Остали смо код куће јер је цео дан падала киша.
We stayed home because it rained all day.
Ако се време поправи, сутра ћемо ићи на излет.
If the weather improves, we'll go on an outing tomorrow.
Perfective present завршиш/поправи can refer to a bounded future event under кад/ако; it is not a standalone future tense.
Clause order and punctuation
An adverbial clause can precede or follow the main clause. Initial clauses are normally followed by a comma; a closely integrated final clause often is not.
Пошаљи ми записник кад завршиш уређивање.
Send me the minutes when you finish editing them.
Кад завршиш уређивање, пошаљи ми записник.
When you finish editing them, send me the minutes.
Complement да clauses normally are not separated from their selecting verb by a comma: Мислим да је у праву. Supplementary relative clauses do take commas, while restrictive ones do not. Punctuation follows syntactic and informational relations, not a universal “comma before every conjunction” rule.
Each finite clause has structure
Јуче сам чуо да ти је Марко послао уговор.
Yesterday I heard that Marko sent you the contract. (male speaker)
Matrix cluster сам belongs to чуо. Embedded cluster ти је belongs to послао and follows subordinate marker да. Moving ти beside the matrix auxiliary would change or break the dependency.
For a connector-by-connector account of cause, condition, concession, and time, continue with other subordinating conjunctions.
A short edited passage
Кад је састанак почео, директорка је објаснила да ће тим који ради на новом систему остати дуже јер рок истиче у петак.
When the meeting began, the director explained that the team working on the new system would stay longer because the deadline expires on Friday.
The passage nests time кад, content да, restrictive relative који, and cause јер. Singular тим...ће остати controls agreement despite nearby систему.
Practice Tasks
Task 1: Identify the function
Знам да долази; човек који долази; јави се кад дође.
I know that he is coming; the man who is coming; call when he comes. Answer: content, relative modifier, temporal adverbial.
Task 2: Reverse clause order
Остаћемо унутра ако почне олуја. → Ако почне олуја, остаћемо унутра.
We'll stay inside if a storm starts. → If a storm starts, we'll stay inside. Answer: initial adverbial takes a comma.
Common Mistakes
Copying an English infinitive with a different subject
❌ Желим тебе доћи сутра.
Incorrect—Serbian cannot copy English object + infinitive for ‘I want you to come.’
✅ Желим да сутра дођеш код мене.
I want you to come to my place tomorrow.
Giving the relative pronoun the antecedent's case
❌ Срео сам човека којег ради у банци.
Incorrect—који is subject inside the relative clause and must be nominative.
✅ Срео сам човека који ради у банци.
I met the man who works at the bank. (male speaker)
Adding a comma before every да
❌ Мислим, да је овај предлог добар.
Incorrect—selected content clause is not separated from мислим by a comma.
✅ Мислим да је овај предлог добар.
I think this proposal is good.
Key Takeaways
- Subordinate clauses have internal predicates, arguments, agreement, and clitic domains.
- Да, који, што, кад introduce different structural relations, not interchangeable translations.
- Case-rich order remains hierarchical: governors and controllers still determine form.
- Initial adverbial clauses normally take a following comma; selected complements normally do not.
