Reasoning runs in two directions, and Croatian marks them with two different toolkits. You can move backward from an effect to its cause ("I was late because it rained") or forward from a cause to its result ("It rained, therefore I was late"). The trap for English speakers is that English uses the same loose words ("so", "because") in both jobs, while Croatian splits them sharply by grammar: cause is expressed mainly by subordinating conjunctions that sit inside the sentence (jer, budući da), and result is expressed mainly by discourse markers that open a new sentence (stoga, dakle, prema tome). Mixing the two — putting jer at the head of a sentence, or stoga in the middle as if it were a conjunction — is the single most common structural error here. This page sorts them out.
Cause: jer, budući da, zbog toga što
Jer "because" is the everyday causal conjunction. It is subordinating, which means it introduces a dependent clause that normally follows the main clause — jer cannot comfortably open a sentence in neutral prose. Budući da "since, given that" is its more formal cousin; crucially, budući da can front a sentence (it puts the cause first). Zbog toga što "because of the fact that, owing to the fact that" is the heavier, explicit causal connector, built on the preposition zbog (see abstract and causal prepositions).
| Connector | Meaning | Position | Register |
|---|---|---|---|
| jer | because | mid-sentence, cause follows | neutral, everyday |
| budući da | since, given that | can front the sentence | (formal) |
| zbog toga što | because of the fact that | mid-sentence, explicit | (formal) emphatic |
Ostao sam kod kuće jer mi nije bilo dobro.
I stayed home because I wasn't feeling well. — 'jer' introduces the cause, following the main clause.
Budući da je rok blizu, moramo požuriti.
Since the deadline is near, we have to hurry. — 'budući da' fronts the cause.
Otkazali su let zbog toga što je magla bila pregusta.
They cancelled the flight because the fog was too thick. — explicit 'zbog toga što'.
One genuine exception: jer can stand alone as a full reply to Zašto? "Why?" — Zašto plačeš? — Jer mi je žao. "Why are you crying? — Because I'm sorry." But that is an elliptical answer, not a fronted clause.
Result and "therefore": zato, stoga, dakle, prema tome
The forward direction — from cause to result — is carried mainly by sentence-initial discourse markers. Zato "that's why, so" is the everyday one. Stoga "therefore, hence" is its more formal, written counterpart. Dakle "so, thus, therefore" draws a conclusion from what was said (it is also a thinking-aloud filler, "so…"). Prema tome "accordingly, consequently" is formal and signals a logical consequence. All four typically open a new sentence, set off by a comma where needed; none of them subordinates a clause the way jer does.
Vlak je kasnio. Zato smo propustili početak.
The train was late. That's why we missed the beginning. — 'zato' opens the result sentence.
Podaci su nepotpuni. Stoga zaključak nije pouzdan.
The data are incomplete. Therefore the conclusion is not reliable. — formal 'stoga'.
Svi su glasali za. Dakle, prijedlog je prihvaćen.
Everyone voted in favour. So, the proposal is accepted. — 'dakle' draws the conclusion.
Ugovor je istekao. Prema tome, više nismo obvezni plaćati.
The contract has expired. Accordingly, we are no longer obliged to pay. — formal 'prema tome'.
There is a useful pair distinction. Zato and stoga mark a consequence in the world (cause → effect). Dakle and prema tome mark a conclusion in the reasoning (premise → inference). "The train was late, stoga we missed it" is a real-world result; "Everyone agrees, dakle it's settled" is a logical inference. English "so" blurs both; Croatian lets you be precise.
Conclusion and summing up: dakle, ukratko
To wrap up a stretch of discourse, Croatian uses dakle "so, in sum" (doing double duty as both consequence and conclusion marker) and ukratko "in short, in brief". Ukratko signals that what follows is a compressed restatement of the point — the natural opener for a closing sentence.
Ukratko, projekt je propao zbog lošeg planiranja.
In short, the project failed because of poor planning.
Dakle, slažemo se da treba pričekati.
So, we agree that we should wait. — 'dakle' sums up and concludes.

Common Mistakes
❌ Jer je padala kiša, ostali smo kod kuće.
Wrong position — bare 'jer' does not front a sentence; use 'Budući da' to put the cause first, or move 'jer' after the main clause.
✅ Budući da je padala kiša, ostali smo kod kuće.
Since it was raining, we stayed home. — 'budući da' fronts the cause.
❌ Bilo je kasno, stoga smo otišli, jer smo bili umorni.
Tangled — 'stoga' opens a result sentence, it isn't a mid-clause glue. Separate the result from the added reason: 'Bilo je kasno. Stoga smo otišli, jer smo bili umorni.'
✅ Bilo je kasno. Stoga smo otišli.
It was late. So we left. — 'stoga' opens the result sentence.
❌ Zakasnio sam zato je padala kiša.
Wrong direction — 'zato' alone means 'that's why'; for 'because' you need 'zato što' (or 'jer'): 'Zakasnio sam jer je padala kiša.'
✅ Zakasnio sam jer je padala kiša.
I was late because it was raining. — 'jer' for the backward-looking cause.
❌ Svi se slažu, prema tome se slažemo.
Overformal and circular — 'prema tome' draws a fresh inference, not a restatement of the same fact; use 'dakle' to conclude: 'Svi se slažu, dakle stvar je riješena.'
✅ Svi se slažu. Dakle, stvar je riješena.
Everyone agrees. So the matter is settled. — 'dakle' concludes.
Key Takeaways
- Cause is mostly subordinating: jer "because" (mid-sentence, follows the main clause), budući da "since" (formal, can front), zbog toga što "because of the fact that" (heavy, explicit).
- Result is mostly sentence-initial markers: zato "that's why" (everyday), stoga "therefore" (formal), prema tome "accordingly" (formal).
- Don't front bare jer outside one-word answers to Zašto?; don't use stoga/dakle as mid-clause glue — they open sentences.
- zato (result) vs. zato što (cause) — one što reverses the direction of reasoning.
- zato/stoga = real-world consequence; dakle/prema tome = logical conclusion; ukratko and dakle also sum up to close.
