The complex sentence in full: cause, purpose, time, concession — and the comma

Four links used to be enough for "because" and "if". Adult speech demands the full set: cause comes in three grades, purpose in two, and concession puts the comma where you do not expect it. Here is the map, group by group — and everywhere: where the comma goes and what happens to the clitic. For example: “Пошто нам је отказан лет, остали смо још један дан” — Since our flight was cancelled, we stayed one more day. A…

How it works

Four links used to be enough for "because" and "if". Adult speech demands the full set: cause comes in three grades, purpose in two, and concession puts the comma where you do not expect it. Here is the map, group by group — and everywhere: where the comma goes and what happens to the clitic.

Cause. Zato što — the commonest, the spoken one: Ne idem, zato što pada kiša. Jer — the same in one word, bookish: Ne idem jer pada kiša. Pošto — "since", and it likes to go first: Pošto pada kiša, ostajemo. Zbog toga što — the heavyweight, for documents. The trap: zato without što is no longer a cause but a consequence — "so, therefore".

Purpose. Here is a fork English knows well, Serbian just marks it differently. If the doer is one and the same person, use da plus the present: Došao sam da pomognem — I came to help. If the persons differ — still da, but with the other person of the verb: Došao sam da mi pomogneš — I came for you to help me. And kako bi is the bookish, newspaper variant of purpose, followed by the conditional: kako bi smanjili troškove. In speech kako bi sounds like a headline; on paper the reverse.

Time. Kad — plain "when". Dok — "while" and "as" at once. Čim — "as soon as". Pre nego što and nakon što — before and after, three words that refuse to be shortened. Otkako — "since". The common rule for all of them: the future is spoken in the present. Kad stignem, not "kad ću stići".

Concession. Iako and mada — "although", interchangeable. Uprkos tome što — "despite the fact that". And remember separately: uprkos without tome što takes the to-case: uprkos kiši — despite the rain.

Now the thing that earns this note the last place in the course. The comma is set when the clause comes first: Iako je hladno, šetamo. And skipped when it follows: Šetamo iako je hladno. English mostly agrees here — the difference is that Serbian is strict about it.

And the connectives — međutim, dakle, naime, uzgred, na primer — are not conjunctions and behave the opposite way: they are fenced with commas always, on both sides, when they stand mid-sentence. And this re-seats the clitic: after a comma the positions count from zero, so Međutim, on je zakasnio puts je second within the clause, not right after međutim. Writing "Međutim je on zakasnio" promotes the connective to first member of the sentence, and the phrase breaks.

    Pošto nam je otkazan let, ostali smo još jedan dan
    Since our flight was cancelled, we stayed one more day
  • Влада мења закон како би смањила трошкове
    Vlada menja zakon kako bi smanjila troškove
    The government is changing the law to cut costs

    He, however, only arrived after the meeting

How the rule settles in your head

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.

Frequently asked

The complex sentence in full: how does it work in Serbian?

Four links used to be enough for "because" and "if". Adult speech demands the full set: cause comes in three grades, purpose in two, and concession puts the comma where you do not expect it. Here is the map, group by group — and everywhere: where the comma goes and what happens to the clitic.

What does it look like in an example sentence Serbian?

“Пошто нам је отказан лет, остали смо још један дан” (Pošto nam je otkazan let, ostali smo još jedan dan) — Since our flight was cancelled, we stayed one more day. A rule is easier to test on sentences like this than to memorize as a wording: what surfaces in conversation is the sentence.
