El festival de cine reúne a mucha gente del barrio.

De cine is a very common Spanish way to classify or describe something by its type or subject.

So festival de cine means film festival or literally festival of cinema.

A few similar examples:

• museo de arte = art museum
• tienda de ropa = clothes shop
• clase de inglés = English class

You would not normally say festival del cine here, because del cine would sound more like of the cinema / of cinema in general in a more specific or abstract sense, not the standard label for the kind of festival it is.

Reúne is the third person singular present of reunir, meaning to gather, to bring together, or to attract together.

Because the subject is El festival de cine, the verb has to be singular:

• el festival reúne
• not reúnen

In this sentence, reúne suggests that the festival brings together a lot of people.

The accent mark in reúne shows that the u is pronounced in a separate syllable from the e.

So it is pronounced roughly as:

• re-ú-ne

Without the accent, Spanish spelling rules would tend to make those vowels blend differently. The written accent helps show the correct stress and syllable pattern.

This also happens in related forms:

• reúno
• reúnes
• reúnen

But:

• reunir has no written accent in the infinitive

This is the personal a.

In Spanish, when the direct object refers to people or other specific animate beings, you often use a before it.

So:

• reúne a mucha gente

Even though in English we do not add anything like this, in Spanish it is normal.

Compare:

• Veo a mi hermano = I see my brother
• Conozco a mucha gente = I know a lot of people

Here, mucha gente refers to people, so the a is used.

Because gente is a singular feminine noun in Spanish.

Even though it refers to many people, grammatically it is singular:

• mucha gente
• not muchas gente

This is similar to how some collective nouns work in English, though the grammar is more clearly singular in Spanish.

That is also why you would usually say:

• La gente es...
• not La gente son...

Because the verb agrees with the subject, not with gente in this sentence.

The subject is:

• El festival de cine

That is singular, so the verb is singular:

• reúne

Also, gente is not the subject here; it is the direct object.

So the structure is:

• El festival de cine = subject
• reúne = verb
• a mucha gente del barrio = object

Del barrio means from the neighbourhood or from the local area.

It modifies gente, so it tells you which people:

• mucha gente del barrio = a lot of people from the neighbourhood

So it does not describe the festival; it describes the people.

You can think of it as:

• gente
  • del barrio
• people + from the neighbourhood

Because de + el normally contracts to del in Spanish.

So:

• de + el barrio → del barrio

This contraction is required in standard Spanish.

A similar contraction is:

• a + el → al

Example:

• Voy al centro

One important exception: If el is part of a proper name, you do not contract:

• de El Escorial
• not del Escorial when referring to the proper name itself

In standard Spanish, with gente meaning people, reúne a mucha gente is the normal and correct form because of the personal a.

If you leave out a, it may sound non-standard or unnatural to many speakers in this context.

So for learners, the safe choice is:

• reúne a mucha gente

Its basic meaning is neighbourhood or district.

In many contexts, el barrio suggests the local area where people live, often with a community feeling. Depending on context, it can sound like:

• neighbourhood
• district
• local area

In this sentence, it most naturally means the local neighbourhood that the people come from.

That would change the meaning.

• El festival reúne a mucha gente = the festival brings together / gathers a lot of people
• Mucha gente se reúne en el festival = a lot of people gather at the festival

So:

• reunir = to gather something/someone, to bring together
• reunirse = to gather, to meet up

Both are correct verbs, but they describe the situation from different angles.

Spanish often uses the definite article more than English does.

Here, El festival de cine refers to a specific festival, or to the festival already understood from context.

So el is natural because it identifies the noun:

• el festival = the festival

If you said Un festival de cine, that would mean a film festival, which is less specific.

In Spain, a careful pronunciation would be roughly:

el fes-ti-VAL de CI-ne re-Ú-ne a MU-cha HEN-te del BA-rrio

A few useful points:

• reúne has the stress on ú
• gente has a strong j-like sound for g
• rr in barrio is a rolled or strong r
• ll in barrio is usually pronounced like y in most of Spain today

The sentence flows quite smoothly, especially:

• reúne a where the vowels run together naturally in speech
