Advokat često zove korisnika.

Because it is the direct object of the verb zove.

In Serbian, masculine nouns referring to people or other animate beings usually change in the accusative singular. So:

• korisnik = nominative singular, used for the subject
• korisnika = accusative singular, used for the direct object

Here:

• Advokat = the lawyer, the subject
• zove korisnika = calls the user/customer, the object

So korisnika shows that this is the person being called.

Because advokat is the subject of the sentence, so it is in the nominative singular.

The basic dictionary form of a noun is usually the nominative singular, and here that form is:

• advokat = lawyer

So in this sentence:

• Advokat = the one doing the action
• korisnika = the one receiving the action

Serbian often shows these roles through case endings, not just word order.

It is accusative singular.

The verb zvati when it means to call (someone) takes a direct object, and the direct object goes in the accusative.

For a masculine animate noun like korisnik, the accusative singular is:

• korisnik → korisnika

This is a very common pattern in Serbian.

Yes, in this sentence that is the most natural meaning.

The verb zvati can mean several related things, including:

• to call someone
• to name someone
• to be called in some constructions

But in Advokat često zove korisnika, the normal meaning is:

• The lawyer often calls the user/customer/client

Without more context, English calls is the best match.

Zove is the 3rd person singular present tense of the verb zvati.

That means it matches a singular subject like:

• on/ona/ono
• or a noun such as advokat

So:

• ja zovem = I call
• ti zoveš = you call
• on/ona zove = he/she calls

Since advokat is singular, zove is the correct form.

Because često is an adverb meaning often, and in Serbian adverbs of frequency commonly appear before the verb.

So:

• Advokat često zove korisnika. = The lawyer often calls the user.

This is a very natural word order. But Serbian word order is fairly flexible, so you may also hear:

• Advokat zove korisnika često.
• Često advokat zove korisnika.

These can sound slightly different in emphasis, but the basic meaning stays the same.

No. Serbian does not have articles like English the and a/an.

So:

• advokat can mean a lawyer or the lawyer
• korisnika can mean a user/customer or the user/customer

The exact meaning depends on context.

That is why a short Serbian sentence can sometimes be translated into English in more than one way.

It most naturally describes a habitual/repeated action:

• The lawyer often calls the user/customer.

The adverb često strongly suggests repetition, and the present tense in Serbian is commonly used for habits and regular actions.

So this is not just is calling right now, but more like often calls in general.

Yes. Serbian word order is more flexible than English because case endings help show who is doing what.

The neutral version is:

• Advokat često zove korisnika.

But you could also see:

• Korisnika često zove advokat.
• Često advokat zove korisnika.
• Advokat korisnika često zove.

These versions may shift the focus or emphasis, but the cases still show that:

• advokat is the subject
• korisnika is the object

Korisnik literally means user, but depending on context it can also mean:

• customer
• client
• service user
• account holder

So the best English translation depends on the situation. For example:

• in technology: user
• in business or services: customer/client
• in administration or social services: beneficiary/service user

You know it mainly from the case forms.

• Advokat is in the nominative → subject, the one doing the action
• korisnika is in the accusative → direct object, the one receiving the action

So the sentence means:

• The lawyer calls the user/customer

not

• The user/customer calls the lawyer

Even if the word order changes, the case endings still tell you the grammatical roles.

Yes, the final -e is fully pronounced.

A rough guide:

• zove ≈ ZO-veh
• često ≈ CHES-to
• advokat ≈ ad-vo-KAT
• korisnika ≈ ko-RIS-ni-ka

A few helpful pronunciation notes:

• č sounds like ch in church
• Serbian vowels are usually clear and fully pronounced
• unstressed vowels are not reduced as much as in English

So do not pronounce zove like English zove with a silent vowel at the end; say both syllables clearly.

Yes, advokat is a masculine noun, and yes, that matters for grammar.

Gender affects things like:

• adjective agreement
• pronouns
• some case endings

In this sentence, gender matters especially because korisnik is also masculine and animate, which is why its accusative changes to korisnika.

So understanding that these are masculine nouns helps explain why the forms look the way they do.
