Prodavac čuva garanciju.

Because garanciju is the direct object of the verb čuva.

The dictionary form is garancija. But in this sentence it has to be in the accusative singular:

• garancija = nominative singular
• garanciju = accusative singular

This happens with many feminine nouns ending in -a:

• knjiga → knjigu
• torba → torbu
• garancija → garanciju

So Prodavac čuva garanciju literally has:

• Prodavac = subject
• čuva = verb
• garanciju = object

Čuva is the 3rd person singular present tense of čuvati.

So it means:

• he/she/it keeps
• he/she/it is keeping
• depending on context, even protects, holds onto, or stores

In this sentence, the subject is prodavac, so čuva means:

• the seller keeps
• the seller is keeping

Because Serbian does not use articles like English a/an/the.

So prodavac can mean:

• a seller
• the seller

And garanciju can mean:

• a warranty
• the warranty

Which one sounds best depends on context. Serbian leaves that information unstated unless something else makes it clear.

Prodavac usually means seller, salesman, shop assistant, or clerk, depending on context.

A few useful notes:

• It is a masculine noun
• Its basic form here is nominative singular
• It refers to a male person grammatically

The feminine form is usually prodavačica.

In real life, English translations can vary:

• seller
• sales clerk
• salesman
• store employee

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

The sentence structure is:

• Prodavac = nominative subject
• čuva = verb
• garanciju = accusative object

If prodavac had a different role in the sentence, it could change form. For example:

• Vidim prodavca. = I see the seller.
  Here prodavca is accusative.

So in your sentence, prodavac stays in its basic form because it is the one doing the action.

Čuvati is imperfective.

That means it usually describes:

• an ongoing action
• a repeated action
• a general habit or state

So čuva suggests something like:

• is keeping
• keeps
• looks after
• holds onto

That fits naturally here: the seller is in possession of the warranty, or keeps it safe.

A perfective verb would focus more on a completed action. For learners, the key point is:

• čuvati = ongoing/habitual
• čuva = present tense of that ongoing/habitual verb

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

The neutral order here is:

• Prodavac čuva garanciju.

But you could also hear:

• Garanciju čuva prodavac.
• Čuva garanciju prodavac.

These alternatives can add emphasis or shift focus. For example:

• Garanciju čuva prodavac.
  Emphasis on the warranty

Even though the order changes, the endings still tell you:

• prodavac = subject
• garanciju = object

Č is pronounced like ch in church.

So:

• čuva sounds roughly like CHOO-va

A rough pronunciation of the whole sentence is:

• pro-DA-vats CHOO-va ga-RAN-tsi-yu

A few details:

• c in prodavac sounds like ts
• č in čuva sounds like ch
• ci in garanciju sounds like tsi
• ju sounds like yu

It can mean either, depending on context.

In everyday situations involving products, receipts, repairs, and stores, garancija often means:

• warranty

In a broader sense, it can also mean:

• guarantee

So the exact English word depends on the situation, even if the Serbian word is the same.

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

Here, čuva already tells you it is 3rd person singular:

• he/she/it keeps

Since the noun prodavac is already there, adding a pronoun would be unnecessary.

English needs:

• The seller keeps the warranty.

Serbian naturally says:

• Prodavac čuva garanciju.

Yes. The verb čuvati has a broader meaning than just keep.

Depending on context, it can mean:

• keep
• hold onto
• preserve
• guard
• look after
• keep safe

So Prodavac čuva garanciju could suggest:

• the seller has the warranty
• the seller is holding onto it
• the seller is keeping it safe

The most natural English translation depends on the situation.
