Požurite i obavestite primaoca.

Because -te is the normal ending for the 2nd person plural imperative in Serbian.

That form is used:

• when speaking to more than one person, and
• when speaking politely/formally to one person.

So Požurite i obavestite primaoca. can mean:

• a command to several people, or
• a formal/polite command to one person.

It would be:

Požuri i obavesti primaoca.

Here the imperative forms are singular:

• požuri = hurry
• obavesti = inform / notify

So:

• požuri / obavesti = singular informal
• požurite / obavestite = plural or formal

The dictionary forms are:

• požuriti = to hurry, to make haste
• obavestiti = to inform, to notify

The sentence uses their imperative forms:

• požurite ← požuriti
• obavestite ← obavestiti

Because primaoca is in the accusative case, which is used for the direct object of the verb obavestiti.

The noun is primaoc = recipient. Since it refers to a person, it is a masculine animate noun. In Serbian, masculine animate nouns usually take an accusative form that matches the genitive.

So:

• primaoc = nominative
• primaoca = accusative

That is why the sentence says:

obavestite primaoca = notify the recipient

not obavestite primaoc.

Both požuriti and obavestiti are perfective verbs here, which is very common in commands when you want someone to do a single, complete action.

The idea is:

• požurite = hurry up
• obavestite = make sure the notification is actually done

If imperfective verbs were used instead, the meaning could sound more like an ongoing or repeated process, depending on context.

So this sentence sounds like a clear instruction to complete two actions.

Yes. I usually means and.

In this sentence it connects two commands:

• Požurite = Hurry up
• i obavestite primaoca = and notify the recipient

In English, this often feels like and then as well, because the actions are naturally understood as part of a sequence:

• hurry up, and notify the recipient

But the actual word is simply i = and.

Because Serbian usually does not need subject pronouns when the verb ending already shows the person and number.

Here -te already tells you the command is addressed to:

• you all, or
• you in a formal sense

So vi is unnecessary.

You could say:

Vi požurite i obavestite primaoca.

but that would usually add emphasis, contrast, or a special tone. The version without vi is more natural in most cases.

That is a very good question, because forms like požurite and obavestite can look identical to 2nd person plural present forms.

You know they are imperatives here because of context:

• the sentence is a direct instruction
• it consists of two bare verb forms joined by i
• this is a very typical command pattern in Serbian

So in this sentence, the natural reading is:

Hurry up and notify the recipient.

not a regular statement.

A few sounds may stand out to English speakers:

• ž in požurite sounds like the s in measure
• c in primaoca sounds like ts in cats

A rough pronunciation guide is:

• požurite ≈ po-zhu-ree-te
• obavestite ≈ o-ba-ves-ti-te
• primaoca ≈ pree-ma-o-tsa

Also, in primaoca, the a-o are pronounced separately.

Yes. That is a common regional/standard variation.

This sentence is in Ekavian Serbian:

• obavestite

In Ijekavian, you would often see:

• obavijestite

So both are related forms, and the difference is mainly one of standard pronunciation/spelling variety, not meaning.

For example:

• Požurite i obavestite primaoca.
• Požurite i obavijestite primaoca.

Both mean the same thing.
