Na festival dolaze susjedi iz cijelog susjedstva.

Both na and u can translate as “to / at / in”, but they’re used in different contexts.

• na + accusative (na festival) is used for:

  • events: na koncert, na utakmicu, na zabavu, na festival
  • surfaces / open areas: na stol, na plažu

• u + accusative (u) is used for going into an enclosed space:

  • u kuću (into the house)
  • u školu (to school, into the building)

A festival is treated as an event you attend, so Croatian uses na festival, not u festival.

Festival is in the accusative singular: na festival.

Reason:

• The preposition na with motion (going somewhere) takes the accusative.
• The verb dolaziti (they are coming) expresses movement toward a destination.

Pattern:

• Idem na festival. – I am going to the festival.
• Dolaze na festival. – They are coming to the festival.

The subject is susjedi (neighbors).

Structure:

• Na festival – prepositional phrase (destination)
• dolaze – verb (3rd person plural)
• susjedi – subject (who is coming?)

You can reorder it to see this clearly:

• Susjedi iz cijelog susjedstva dolaze na festival.
  → Susjedi (subject) dolaze (verb) na festival (where to).

The verb dolaze is plural to agree with plural susjedi.

• susjed – a (male) neighbor
• susjedi – neighbors (plural, people)
• susjedstvo – the neighborhood (the area / community)

In the sentence:

• susjedi = the actual people who are coming
• iz cijelog susjedstva = from the whole area / neighborhood

So it literally says:
Neighbors from the whole neighborhood are coming to the festival.

It can sound repetitive in English, but in Croatian it’s natural and adds emphasis:

• susjedi – tells you who is coming (neighbors, not strangers)
• iz cijelog susjedstva – adds how many / from where exactly (not only from one building or one street, but from all over the neighborhood)

It has the nuance:

• “Neighbors from all over the neighborhood are coming.”

You could drop the phrase and say just:

• Na festival dolaze susjedi. – Neighbors are coming to the festival.

But then you lose the idea of from the entire neighborhood.

Both iz and od can translate as “from”, but:

• iz is used for:
  • from inside a place / area:
    
    • iz kuće (from the house)
    • iz grada (from the city)
    • iz susjedstva (from the neighborhood)
• od is used more for:
  • from a person or source:
    
    • dobio sam pismo od prijatelja (I got a letter from a friend)
    • posudio sam knjigu od njega (I borrowed a book from him)

Since susjedstvo is an area, the natural choice is iz susjedstva.

Cijelog susjedstva is in the genitive singular.

• susjedstvo (neuter noun) → genitive singular: susjedstva
• cijelo (neuter adjective “whole”) → genitive singular: cijelog

Reason:

• The preposition iz always takes the genitive case.
• Adjectives must agree with the noun in gender, number, and case.
  So cijelog agrees with genitive singular neuter susjedstva.

Nominative (dictionary form) would be:

• cijelo susjedstvo – the whole neighborhood

In the sentence, because of iz, we get:

• iz cijelog susjedstva – from the whole neighborhood

You can say Na festival dolazi susjedstvo, but it sounds a bit more abstract:

• Na festival dolazi susjedstvo.
  → “The neighborhood is coming to the festival” (as a community, as a whole group)

The original sentence:

• Na festival dolaze susjedi iz cijelog susjedstva.
  → emphasizes individual people (neighbors) coming, from all over the neighborhood.

So:

• susjedi iz cijelog susjedstva – focuses on the people, and suggests many and from everywhere in that area.
• susjedstvo dolazi – can sound like you’re treating the neighborhood as a single unit.

Both are understandable; the original is more natural if you want to talk about people actually attending.

Yes, you can, and the basic meaning stays the same.

Both are correct:

• Na festival dolaze susjedi iz cijelog susjedstva.
• Susjedi iz cijelog susjedstva dolaze na festival.

Nuances:

• Starting with Na festival slightly emphasizes the event:
  → “To the festival, (it is) neighbors from the whole neighborhood (who) are coming.”
• Starting with Susjedi iz cijelog susjedstva emphasizes who is coming.
  This is closer to normal English word order: subject–verb–place.

Croatian word order is flexible; grammar is shown mostly by endings, not position.

The verb must agree with the subject in person and number.

• Subject: susjedi – plural (neighbors)
• Verb: dolaziti (to come), 3rd person plural present: dolaze

Conjugation (present, for reference):

• ja dolazim – I come / am coming
• ti dolaziš – you come
• on/ona/ono dolazi – he/she/it comes
• mi dolazimo – we come
• vi dolazite – you (pl/formal) come
• oni/one/ona dolaze – they come

Since it’s “they (neighbors) are coming”, we use dolaze.

Croatian has aspect:

• dolaziti – imperfective (process, repeated / ongoing)
• doći – perfective (single, completed arrival)

In the sentence:

• Na festival dolaze susjedi iz cijelog susjedstva.
  → describes a general or ongoing situation:
  “(The) neighbors are coming / come (to the festival).”

If you want to emphasize the completed act of arriving (future or one-time), you’d use doći:

• Na festival će doći susjedi iz cijelog susjedstva.
  → Neighbors from the whole neighborhood will come (will arrive) at the festival.

So:

• dolaze – focuses on the process / habit / current action.
• doći – focuses on the moment of arrival as a single event.

Susjedi is pronounced roughly like: [SOOS-ye-dee].

Breakdown:

• su – like “soo”
• sj – pronounced like “sy” or a soft “s” + “y”
• je – like “ye” in “yes” (this is where j = English y)
• di – like “dee”

In Croatian:

• j is always pronounced like English “y” in yes.
• It never makes a “dʒ” sound like English “j” in job.

So susjedi ≈ “SOOS-ye-dee”, not “sus-jed-ee”.

Croatian has no articles (the, a, an), so susjedi by itself can mean:

• the neighbors
• (some) neighbors
• neighbors in general

Context decides. In this sentence:

• Na festival dolaze susjedi iz cijelog susjedstva.

Because it says “from the whole neighborhood”, in natural English we would usually translate it as:

• “The neighbors from the whole neighborhood are coming to the festival.”

But grammatically, Croatian doesn’t mark “the” vs “a”; that’s an interpretation based on context.
