Conjunction 'Jer' for Cause (Because)
Grammar Rule in 30 Seconds
Use 'jer' to explain the reason for an action, but remember it can never start a sentence in standard Croatian.
- Place 'jer' between two clauses to show cause: 'Učim jer želim znati' (I study because I want to know).
- Always put a comma before 'jer' in written Croatian to separate the clauses clearly.
- Never start a sentence with 'jer'; use 'budući da' or 'kako' if the cause comes first.

자주 묻는 질문 (8)
In very informal speech or texting, people might do it, but it's considered grammatically incorrect. It's better to use `Zato što` if you must start with 'because' in a casual way.
No, the meaning is identical. The difference is stylistic: `jer` is shorter and more common in writing, while `zato što` is more common in spoken language.
In Croatian grammar, `jer` introduces a dependent (subordinate) clause. Commas are used to separate the main thought from the secondary thought that explains it.
No. `Jer` is only for cause (because). For purpose (so that), you must use `da` or `kako bi`.
The most formal ways are `budući da` (since/given that) or `uslijed` (due to) followed by a noun in the genitive case.
No, `jer` is a conjunction, not a preposition. It connects clauses, so the nouns in the following clause follow standard case rules based on their role in that clause.
You say `samo zato što`. You wouldn't typically say `samo jer`.
Yes, `jer` is standard across all of Croatia, though some regions might use local variants like `zato kaj` (Zagreb) or `jerbo` (archaic/rural).
In Other Languages
because
Sentence-initial position is forbidden for 'jer'.
porque
Spanish doesn't require a comma before 'porque' as strictly as Croatian does before 'jer'.
weil / denn
No verb-final word order in Croatian.
car / parce que
French 'car' is coordinating, while 'jer' is subordinating.
kara / node
Word order: Croatian is Result-Jer-Cause; Japanese is Cause-Kara-Result.
yīnwèi (因为)
Croatian doesn't use a 'therefore' correlative with 'jer'.
li'anna (لأن)
