Zvučnik pušta plejlistu.

Here zvučnik means a speaker / loudspeaker, the audio device.

It does not normally mean a speaker in the sense of a person who is speaking. For a person, Serbian would usually use a different word depending on the context.

So in this sentence, Zvučnik pušta plejlistu. means the device is playing the playlist.

The basic form is puštati.

In this sentence, pušta is:

• 3rd person singular
• present tense
• from the imperfective verb puštati

So literally it is something like:

• the speaker plays
• the speaker is playing
• the speaker lets out / runs

In this context, puštati is commonly used for playing audio, music, a track, a playlist, a video, etc.

Yes — puštati has a broad meaning. Its core idea is something like to let go, to let, to release, or to set in motion.

From that core meaning, it also developed the common media-related meaning:

• puštati muziku = to play music
• puštati film = to play/show a movie
• puštati plejlistu = to play a playlist

So this is very natural Serbian usage. In everyday speech, puštati is one of the main verbs used for playing recorded media.

Because plejlistu is in the accusative singular.

The noun plejlista is feminine, and its basic form is:

• plejlista = playlist

But here it is the direct object of the verb pušta, so it goes into the accusative:

• plejlista → plejlistu

So:

• Zvučnik = subject
• pušta = verb
• plejlistu = direct object

This is a very common pattern in Serbian.

It is a borrowed word from English, but it is very common and natural in modern Serbian.

Serbian often adapts borrowed words to Serbian spelling and grammar:

• playlist → plejlista

Then it declines like a normal Serbian noun:

• plejlista (nominative)
• plejlistu (accusative)
• etc.

So even though the word comes from English, it behaves like a regular Serbian word in the sentence.

Because Serbian does not have articles like a / an / the.

So zvučnik can mean:

• a speaker
• the speaker

And plejlistu can mean:

• a playlist
• the playlist

Which one is meant depends on context.

So Zvučnik pušta plejlistu. could mean:

• The speaker is playing the playlist.
• A speaker is playing a playlist.

In many learning examples, English uses the because it sounds most natural in context, but Serbian itself does not mark that distinction with articles.

A simple learner-friendly pronunciation guide would be:

zvučnik ≈ ZVOOCH-neek

A few details:

• zv is pronounced together at the start
• č sounds like ch in chocolate
• i is like ee in see
• Serbian pronunciation is generally quite phonetic, so words are usually pronounced close to how they are written

And:

• pušta ≈ POOSH-tah
• plejlistu ≈ PLAY-lee-stoo

It is in the present tense, but Serbian present tense can often translate into English in more than one way.

So Zvučnik pušta plejlistu. can mean:

• The speaker plays a playlist.
• The speaker is playing a playlist.

Which translation is best depends on context.

Because the verb is imperfective (puštati), it is especially natural for:

• ongoing actions
• repeated actions
• habitual actions

So in many situations, is playing is a very good translation.

The perfective partner is pustiti.

This is a very important Serbian verb pair:

• puštati = imperfective
• pustiti = perfective

Very roughly:

• puštati focuses on the process, repetition, or ongoing action
• pustiti focuses on a single completed action

For example:

• Zvučnik pušta plejlistu. = The speaker is playing / plays a playlist.
• Zvučnik je pustio plejlistu. = The speaker started/played the playlist or has played the playlist, depending on context

English and Serbian do not match perfectly here, but the aspect difference is important.

Yes. Serbian word order is more flexible than English word order.

The neutral order here is:

• Zvučnik pušta plejlistu.

But other orders are possible, for example:

• Plejlistu pušta zvučnik.
• Pušta plejlistu zvučnik.

These alternatives usually change the focus or emphasis, not the basic meaning.

The original sentence sounds like the most neutral, textbook-style version:

• subject + verb + object

Mostly because of the case endings.

• zvučnik is in the nominative, which is the usual case for the subject
• plejlistu is in the accusative, which is commonly used for the direct object

So even if the word order changed, the endings would still help show who is doing the action and what is being affected by it.

That is one reason Serbian can allow more flexible word order than English.

No, but it is one of the most common verbs for playing recorded audio.

Some useful distinctions are:

• puštati muziku = to play music from a device
• svirati = to play an instrument, or sometimes music is playing in a more performance-related sense

So if a phone, computer, or speaker is playing songs, puštati is very natural:

• Telefon pušta muziku.
• Zvučnik pušta plejlistu.

If a person plays the piano, you would usually use svirati:

• On svira klavir.

Zvučnik is masculine.

That matters because Serbian nouns belong to grammatical genders, and this affects:

• adjective endings
• pronouns
• some past-tense forms

In this sentence, you do not see many consequences of that yet, but it is useful to know:

• zvučnik = masculine
• plejlista = feminine

For example, with an adjective:

• nov zvučnik = a new speaker
• nova plejlista = a new playlist

Yes, depending on context, pušta can sometimes feel like:

• is playing
• puts on
• starts playing
• is running

The exact English choice depends on what you want to emphasize.

In many everyday situations, if a device is currently running audio, is playing is the best translation. But the Serbian verb itself is a little broader than just the English word play.
