Zona za odmor je daleko od reflektora.

Yes. Croatian often expresses this idea as noun + za + noun.

• zona = zone / area
• za = for
• odmor = rest

So zona za odmor literally means zone for rest, and in natural English that is rest area or rest zone.

Because za here means for in the sense of purpose, and with that meaning it takes the accusative case.

So:

• odmor = nominative singular
• odmor = accusative singular too

That is why the form does not visibly change. Since odmor is a masculine inanimate noun, nominative and accusative singular are often identical.

Je is the 3rd person singular present of biti (to be), so it means is.

• Zona za odmor je... = The rest area is...

In Croatian, forms like je are clitics, so they usually appear in second position in the sentence or clause. That is why it comes after the subject phrase Zona za odmor.

Here daleko means far, and it functions as a predicative adverb-like word after je.

So:

• je daleko = is far

Croatian often uses daleko this way with biti. You do not need an adjective equivalent of far here.

Because od means from, and od requires the genitive case.

So:

• base form: reflektor
• after od: reflektora

That gives:

• daleko od reflektora = far from the reflector / spotlight / floodlight

It can be either, depending on context.

For many masculine nouns in Croatian, the genitive singular and genitive plural can look the same.

So od reflektora can mean:

• from the reflector / spotlight
  or
• from the reflectors / spotlights

Usually the intended meaning is clear from context or from the translation you were given.

Because Croatian has no articles. There is no direct equivalent of the or a/an.

So Zona za odmor can mean:

• a rest area
• the rest area

The exact meaning depends on context.

Here is the breakdown:

• Zona — nominative singular
  It is the subject of the sentence.

• odmor — accusative singular
  It follows za in the sense of purpose: for rest.

• reflektora — genitive
  It follows od: from the reflector(s).

This sentence is a good example of how Croatian cases are controlled by prepositions.

Yes, Croatian word order is more flexible than English word order. The given sentence is the most neutral and straightforward:

• Zona za odmor je daleko od reflektora.

But other orders are possible for emphasis, for example:

• Daleko od reflektora je zona za odmor.

That version puts more focus on far from the reflector(s). Even when word order changes, the cases still show the grammatical relationships.

Yes, that is possible in some contexts, but it is a slightly different structure.

• zona za odmor = zone for rest
• zona odmora = rest zone / zone of rest

Both can work, but za + accusative very clearly expresses purpose. In everyday usage, zona za odmor sounds very natural for a place intended for resting.

It is neutral standard Croatian. Nothing in it is especially slangy or highly formal.

You could use it in:

• everyday speech
• written descriptions
• signage or instructions
• basic textbook examples

So it is a very useful model sentence for learners.
