Vlasnik računa proverava tekući račun.

Because the noun račun is in two different cases here.

• vlasnik računa = owner of the account

  • vlasnik is the main noun.
  • računa is in the genitive singular, showing possession: of the account.

• tekući račun = current account

  • Here račun is the direct object of proverava.
  • Since račun is a masculine inanimate noun, its accusative singular looks the same as the nominative: račun.

So the sentence uses:

• genitive after another noun: vlasnik računa
• accusative for the thing being checked: tekući račun

Vlasnik is in the nominative singular because it is the subject of the sentence.

The subject is the person doing the action:

• Vlasnik = the owner / account holder
• proverava = checks / is checking

So vlasnik is the one performing the verb, which is why it appears in the nominative.

Because tekući is an adjective agreeing with račun.

In Serbian, adjectives must agree with the noun they describe in:

• gender
• number
• case

Here:

• račun is masculine singular
• it is the direct object, but since it is inanimate, accusative singular looks like nominative singular
• so the adjective also stays in the matching form: tekući

That gives:

• tekući račun = current account

Proverava means checks, verifies, or is checking, depending on context.

It is the 3rd person singular present tense form, so it can mean:

• checks (habitual / general present)
• is checking (current ongoing action)

Serbian present tense often covers both meanings, and English chooses between them based on context.

It is imperfective.

That matters because in Serbian:

• imperfective verbs are used for ongoing, repeated, or general actions
• perfective verbs are used for completed actions

Here, proverava presents the action as a process or regular action: checks / is checking.

A learner will often compare it with a perfective partner such as proveriti. Very roughly:

• proverava = checks / is checking
• proveriće = will check
• je proverio = checked / has checked

So in this sentence, the imperfective form is the natural one.

Because Serbian does not have articles like English a and the.

So:

• vlasnik can mean owner, an owner, or the owner
• račun can mean account, an account, or the account

Whether English uses a or the depends on context, not on a separate Serbian word.

Yes. Serbian word order is more flexible than English word order because case endings show grammatical roles.

The basic neutral order here is:

• Vlasnik računa proverava tekući račun.

But other orders are possible, for example:

• Tekući račun proverava vlasnik računa.
• Vlasnik proverava tekući račun računa. ← this one is not correct for the intended meaning, because it changes structure badly

A changed order usually affects:

• emphasis
• style
• information focus

So although Serbian allows flexibility, not every rearrangement is natural.

This sentence is useful because it contains both:

• računa has č
• tekući has ć

A simple learner-friendly way to think about them:

• č = a harder ch sound, like in English church, but usually cleaner and sharper
• ć = a softer sound, somewhere between English ty and a very soft ch

So:

• račun: the č is harder
• tekući: the ć is softer

English speakers often struggle to hear the difference at first, but it is a real distinction in Serbian.

No. Račun can mean several things depending on context, including:

• account
• bill
• check (restaurant check)
• calculation

In this sentence, the context makes it clear that:

• vlasnik računa = account owner
• tekući račun = current account

So here it is definitely about a bank account, not a restaurant bill or a math calculation.

Yes. Tekući račun is a standard banking expression meaning current account.

Depending on the variety of English, you might also think of it as:

• current account
• sometimes roughly checking account in American usage

So even though tekući by itself can mean running, flowing, or current, the whole phrase tekući račun is a fixed financial term.

Yes, and that would mean the owner of the current account.

Compare:

• vlasnik računa = owner of the account
• vlasnik tekućeg računa = owner of the current account

In tekućeg računa, both the adjective and noun are in the genitive singular because they depend on vlasnik.

So this is a useful comparison:

• vlasnik računa → genitive after vlasnik
• tekući račun → accusative as the direct object
• vlasnik tekućeg računa → adjective + noun both in genitive

Yes, it is grammatically natural.

It sounds like a neutral, standard sentence meaning that the account owner is checking the current account. In real-life usage, context might make speakers choose slightly different wording, but the structure itself is normal and correct.

For example, depending on context, a speaker might also say:

• Vlasnik računa proverava stanje na tekućem računu.
  = The account holder is checking the balance in the current account.

But your original sentence is still a good, solid example of Serbian grammar.
