A közönség énekli a refrént, kiabál és tapsol.

In Hungarian, közönség is a collective noun, so it is grammatically singular, just like audience can be in English.

That is why the verbs are in third person singular:

• énekel
• kiabál
• tapsol

So Hungarian is treating the audience as one group.

If you wanted to talk about the individual people instead, you would use a plural noun such as az emberek or a nézők, and then the verb would be plural.

Because énekel and énekli belong to two different Hungarian verb conjugations:

• énekel = indefinite conjugation
• énekli = definite conjugation

Hungarian uses the definite conjugation when the verb has a specific definite direct object.

Here, the object is:

• a refrént = the chorus / the refrain

Since the object is definite, Hungarian uses:

• A közönség énekli a refrént.

Compare:

• A közönség énekel. = The audience is singing.
• A közönség énekel egy dalt. = The audience is singing a song.
• A közönség énekli a refrént. = The audience is singing the chorus.

So the -i in énekli signals that the verb is agreeing with a definite object.

Because in this sentence they do not have a direct object.

• énekel valamit = sing something
• kiabál = shout / yell
• tapsol = clap

Here:

• énekl i a refrént has a direct object: a refrént
• kiabál has no object
• tapsol has no object

So Hungarian uses:

• definite conjugation for énekl i
• indefinite/default conjugation for kiabál and tapsol

This mixture in one sentence is completely normal.

Because refrént is in the accusative case, which marks the direct object in Hungarian.

The basic noun is:

• refrén = refrain / chorus

As the direct object, it gets -t:

• refrént

So:

• a refrén = the refrain
• a refrént = the refrain, as the thing being sung

This -t ending is one of the most important Hungarian case endings to learn, because it often shows what receives the action.

Hungarian uses definite articles very often, much like English uses the.

Here:

• a közönség = the audience
• a refrént = the chorus/refrain

The article a is used before consonant sounds, while az is used before vowel sounds:

• a közönség
• az ember

In this sentence, both nouns are definite, so both take the definite article.

Also note that Hungarian keeps the article even when the noun is in a case form:

• a refrén
• a refrént

The case ending goes on the noun, not on the article.

Because the same subject, a közönség, applies to all three verbs:

• énekeli a refrént
• kiabál
• tapsol

Hungarian, like English, does not need to repeat the subject when it stays the same.

So this is perfectly natural:

• A közönség énekli a refrént, kiabál és tapsol.

Repeating the subject each time would usually sound unnecessary:

• A közönség énekli a refrént, a közönség kiabál és a közönség tapsol.

That is grammatical, but awkward unless you want strong emphasis.

No, Hungarian word order is fairly flexible, but different orders can change the emphasis.

The given sentence has a neutral, natural flow:

• A közönség énekli a refrént, kiabál és tapsol.

You could also say:

• A közönség kiabál, tapsol és énekli a refrént.

That is still grammatical, but now the order of actions is different, so the rhythm and emphasis feel different.

In Hungarian, word order often reflects information structure rather than rigid grammar. English learners often expect one fixed order, but Hungarian allows more variation.

Still, for a simple descriptive sentence, the original order is very natural.

Hungarian often lists actions with commas and then uses és before the last item, just like English can do:

• sings the chorus, shouts, and claps

So:

• énekeli a refrént, kiabál és tapsol

is a normal Hungarian list of three actions.

You could think of it as:

1. sings the chorus,
2. shouts,
3. and claps.

This structure is very common and natural.

A rough pronunciation guide is:

• kö-zön-shayg

A few important points:

• ö is like the German ö or French eu
• zs is pronounced like the s in measure
• é is a long ay sound
• g at the end is pronounced normally

So közönség sounds roughly like kø-zøn-shaayg, though English does not have exact equivalents for every vowel.

Also, Hungarian stress is normally on the first syllable:

• KÖ-zön-ség

Yes, in many contexts refrén means chorus or refrain in a song.

A useful distinction is:

• refrain is the more literal, general meaning
• chorus is often the most natural translation in modern song contexts

So in this sentence, English speakers will often understand it best as:

• the audience sings the chorus, shouts, and claps

But the Hungarian word itself is very close to refrain.

It can do either, depending on context.

Hungarian present tense often covers both:

• what is happening now
• what generally happens

So this sentence could mean:

• the audience is singing, shouting, and clapping right now
• or, in a descriptive context, the audience sings, shouts, and claps

The surrounding context tells you which reading is intended.

Without extra context, many learners should understand it simply as a present-time description.
