Numeriši kutije u kombiju.

Numeriši is the imperative form, meaning it is a command.

More specifically, it is:

• 2nd person singular
• used when speaking to one person informally (ti)

It comes from the verb numerisati, meaning to number or to mark with numbers.

So Numeriši kutije means you are telling one person: Number the boxes.

You would use Numerišite:

Numerišite kutije u kombiju.

This form is used:

• for more than one person
• for one person formally/politely (Vi)

So:

• informal singular: Numeriši
• plural/formal: Numerišite

The basic dictionary form is kutija, meaning box.

In the sentence, kutije is used because the noun is plural:

• kutija = box
• kutije = boxes

Here it is the direct object of the command, so it is in the accusative plural.

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

• kutije = boxes

So Numeriši kutije literally has the structure Number boxes / the boxes.

U kombiju is in the locative case.

The preposition u can take different cases depending on meaning:

• u + locative = in/inside somewhere, showing location
• u + accusative = into somewhere, showing movement toward a place

Here the meaning is location: the boxes are in the van, so Serbian uses locative:

• u kombiju = in the van

Compare:

• Kutije su u kombiju. = The boxes are in the van.
• Stavi kutije u kombi. = Put the boxes into the van.

Because kombi changes form when it is declined.

The dictionary form is kombi, but after a preposition like u meaning location, Serbian needs the locative singular, which is kombiju.

A simplified pattern is:

• kombi = nominative
• kombija = genitive
• kombiju = dative/locative

So even though the word ends in -i, it is not frozen in one form. Serbian adds endings, often with -j- inserted:

• kombi → kombiju

Serbian does not have articles like English a and the.

So kutije can mean:

• boxes
• the boxes

The exact meaning depends on context.

In a sentence like Numeriši kutije u kombiju, English will usually say the boxes, because the situation normally makes it clear which boxes are meant.

No. Serbian word order is fairly flexible.

The sentence Numeriši kutije u kombiju. is a very natural, neutral way to say it. It starts with the command verb, which is common in instructions.

But other orders are possible, for example:

• U kombiju numeriši kutije.
• Kutije u kombiju numeriši.

These are more marked and may shift the emphasis:

• starting with u kombiju highlights the location
• starting with kutije highlights the boxes

So the original order is probably the most neutral and natural for a basic instruction.

Yes, numerisati is understandable and natural, especially in instructions, inventory work, packing, logistics, or anything technical.

It specifically suggests giving numbers to something.

Depending on context, Serbian speakers might also say:

• označi kutije brojevima = mark the boxes with numbers
• obeleži kutije brojevima = label/mark the boxes with numbers

But Numeriši kutije u kombiju is perfectly good Serbian if the task is literally to number them.

A rough pronunciation is:

Numeriši kutije u kombiju
noo-MEH-ree-shee KOO-tee-yeh oo KOM-bee-yoo

A few helpful sound notes:

• š sounds like English sh
• j sounds like English y
• u sounds like oo in food

Serbian spelling is generally quite phonetic, so once you know the letters, pronunciation is usually straightforward.

In practice, it tells you where the relevant boxes are: they are the boxes in the van.

So in English, the sentence is often understood like:

• Number the boxes that are in the van

It can also be felt as the location of the action, but in normal usage the important idea is that the boxes are the ones located in the van.

Serbian often leaves this kind of relationship to context, and this sentence sounds completely natural as it is.
