Pozvaću agenta.

Pozvaću is future tense, 1st person singular: I will call.

It comes from:

• pozvati = to call / to invite (perfective verb)
• ću = the clitic form of hoću used to make the future

In Serbian, when ću comes directly after an infinitive ending in -ti, the -ti drops and the two parts are written together:

• pozvati + ću → pozvaću

A full version is also possible:

• Ja ću pozvati agenta.

Because Serbian often drops subject pronouns when they are not needed.

The ending -ću already tells you the subject is I. So Pozvaću by itself already means I will call.

You can add ja if you want emphasis or contrast:

• Ja ću pozvati agenta, ne ti. = I will call the agent, not you.

Because agenta is in the accusative case, which is used for the direct object.

Here, the agent is the thing/person being called, so it must be in the accusative:

• agent = nominative
• agenta = accusative

This happens because agent is a masculine animate noun. In Serbian, masculine animate nouns usually take -a in the singular accusative.

Compare:

• Vidim agenta. = I see the agent.
• Pozvaću agenta. = I will call the agent.

But with a masculine inanimate noun, accusative usually looks like nominative:

• Vidim sto. = I see the table.

Serbian does not have articles like English the and a/an.

So agenta can mean:

• the agent
• an agent

The exact meaning depends on the context. English has to choose an article, but Serbian usually leaves that information unstated unless something else makes it clear.

Yes, both patterns exist, but they are used differently in the sentence.

You can say:

• Pozvaću agenta.
• Ja ću pozvati agenta.
• Sutra ću pozvati agenta.

When the future clitic follows the infinitive directly, Serbian writes it together and drops -ti:

• pozvati + ću → pozvaću

But when another word comes before the clitic, you normally use the separate form:

• Ja ću pozvati
• Sutra ću pozvati

So Pozvaću agenta is correct, and Ja ću pozvati agenta is also correct, but Ja pozvaću agenta is not the normal standard form.

This is mainly a question of aspect.

• pozvati = perfective
• zvati = imperfective

In simple terms:

• pozvati presents the call as one complete action
• zvati presents calling as ongoing, repeated, habitual, or less bounded

So:

• Pozvaću agenta. = I’ll call the agent as a single completed action.
• Zvaću agenta. can suggest I’ll be calling the agent, I’ll call him repeatedly, or a less clearly bounded future action, depending on context.

In many everyday situations, both may be possible, but pozvati is very natural when you mean I’ll make the call as a single event.

Yes. Pozvati can mean:

• to call
• to invite
• to summon

The exact meaning depends on context.

So Pozvaću agenta could mean:

• I’ll call the agent
• I’ll summon the agent
• sometimes even I’ll invite the agent

If your translation already gives call, then that is the intended meaning here.

Yes. Serbian word order is fairly flexible, and changing it often changes the emphasis, not the basic meaning.

For example:

• Pozvaću agenta. = neutral
• Ja ću pozvati agenta. = emphasizes I
• Agenta ću pozvati. = emphasizes the agent
• Sutra ću pozvati agenta. = emphasizes tomorrow

So the sentence can be rearranged, but the most natural choice depends on what you want to highlight.

A rough guide is:

• Pozvaću ≈ poz-VAH-ću
• agenta ≈ a-GEN-ta

A few helpful points:

• zv is pronounced clearly as two consonants together
• g in agenta is always a hard g, like in go
• ć is a soft sound, somewhat like a softened ch

The sound ć is softer than č. English does not have an exact equivalent, so learners usually need a bit of practice with it.

It is neutral and standard.

Pozvaću agenta. is a normal everyday sentence. It is not especially formal or especially casual. You could use it in conversation, in a workplace context, or in ordinary written Serbian.
