Istovari kutije pored prilaza.

Istovari is the informal singular imperative of istovariti, which means to unload.

So it is a command addressed to one person:

• Istovari! = Unload!

If you were speaking to more than one person, or using the polite you, you would say:

• Istovarite kutije pored prilaza.

This is a question of aspect, which is very important in Serbian.

• istovariti = perfective verb
• istovarati / istovarivati = imperfective verb

The imperative istovari uses the perfective verb, so it suggests:

• do the action
• complete it
• unload the boxes as a finished task

By contrast, istovaraj would sound more like:

• be unloading
• unload in an ongoing way
• do it repeatedly / as a process

In practical terms, istovari kutije is the natural way to say Unload the boxes when you mean a complete action.

Kutije is the accusative plural of kutija (box).

Here it is the direct object of the verb istovari, because it answers the question what should be unloaded?

• Istovari šta? → kutije

For this noun, the nominative plural and accusative plural look the same:

• kutije = boxes as a subject
• kutije = boxes as a direct object

So the form itself does not change, but the role in the sentence changes.

Because pored requires the genitive case.

The basic noun is:

• prilaz = access / approach / driveway / entrance way

After pored, it becomes:

• prilaza = genitive singular

So:

• pored prilaza = next to the driveway / beside the access way

This is a normal preposition + case pattern in Serbian:

• pored kuće = next to the house
• pored auta = next to the car
• pored prilaza = next to the driveway

Pored usually means:

• next to
• beside
• alongside

In this sentence, it tells you where the boxes should be unloaded:

• pored prilaza = beside the driveway / next to the access road

It is a location word. It does not mean onto or into the driveway, but rather at the side of it.

Prilaz literally refers to an approach, access way, or way leading up to something.

Depending on context, in English it could be translated as:

• driveway
• access road
• approach
• entrance way

So in this sentence, prilaz is probably some kind of place vehicles or people use to reach a building or property.

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

So:

• kutije can mean boxes, the boxes, or sometimes some boxes
• the exact meaning comes from context

In a command like this, English often uses the:

• Unload the boxes next to the driveway.

But Serbian simply says:

• Istovari kutije pored prilaza.

In Serbian, the subject pronoun is often left out, especially with commands.

The verb form already tells you that the speaker is addressing you:

• istovari = command to you singular, informal

So the full idea is:

• (Ti) istovari kutije pored prilaza.

But ti is normally omitted unless you want extra emphasis.

Yes. Serbian word order is relatively flexible.

The version

• Istovari kutije pored prilaza.

is very natural for a direct command.

But you could also hear:

• Kutije istovari pored prilaza.
• Pored prilaza istovari kutije.

These versions shift the emphasis:

• starting with kutije emphasizes the boxes
• starting with pored prilaza emphasizes the location

Even though the order can change, the original sentence is probably the most neutral and natural in many situations.

You would change the imperative from istovari to istovarite:

• Istovarite kutije pored prilaza.

This can mean either:

• command to several people
• polite command to one person

So:

• istovari = informal singular
• istovarite = plural or polite singular

A simple learner-friendly pronunciation is:

• kutije ≈ KOO-tee-ye

The j in Serbian is pronounced like the y in yes, so:

• tije sounds roughly like tee-ye

Likewise:

• prilaza ≈ pree-LA-za
• pored ≈ PO-red
• istovari ≈ ee-STO-va-ree

Serbian spelling is quite phonetic, so once you know the sound of each letter, pronunciation becomes much easier.
