Kurir čeka napolju.

Kurir is a noun meaning courier or delivery person. In this sentence it is in the nominative singular because it is the subject of the verb — the person who is doing the waiting.

Čeka is the 3rd person singular present form of the verb čekati (to wait).

It agrees with kurir, which is a singular subject:

• ja čekam — I wait / I am waiting
• ti čekaš — you wait / are waiting
• on/ona čeka — he/she waits / is waiting
• kurir čeka — the courier waits / is waiting

Because kurir is singular, the verb must also be singular.

It can mean both, depending on context.

In Serbian, the present tense often covers both:

• simple present: waits
• present progressive: is waiting

So Kurir čeka napolju can naturally mean:

• The courier waits outside
• The courier is waiting outside

In everyday English, is waiting outside is usually the more natural translation.

Napolju means outside or outdoors.

In this sentence, it tells you where the waiting is happening:

• Kurir čeka napolju. — The courier is waiting outside.

It functions as an adverb, not as a noun or adjective.

Serbian does not have articles like a or the.

So kurir can mean:

• a courier
• the courier

Which one is meant depends on the context.

In many situations, English will translate it as the courier if the person is already understood from the situation.

Yes, kurir is a masculine noun.

However, in the present tense, the verb form čeka does not change for gender. It only changes for person and number.

So you would still say:

• Kurir čeka.
• Poštarka čeka. — The female postal worker is waiting.

Gender matters more in places like:

• past tense
• adjectives
• some pronouns

But not here in the present-tense verb form čeka.

The dictionary form is čekati, meaning to wait.

This is an imperfective verb, which is the normal choice when describing an ongoing action, repeated action, or general action in the present.

That is why čekati fits naturally in a sentence like Kurir čeka napolju.

Yes. Serbian word order is more flexible than English word order.

The neutral order here is:

• Kurir čeka napolju.

But you could also hear:

• Napolju čeka kurir. — Outside, the courier is waiting.
• Kurir napolju čeka. — possible, but less neutral and more marked

Changing the order usually changes the focus or emphasis, not the basic meaning.

The letter č is pronounced roughly like ch in church, but usually a bit firmer.

A rough English-friendly guide:

• Kurir ≈ koo-REER
• čeka ≈ CHEH-kah
• napolju ≈ nah-PO-lyoo

So the whole sentence is approximately:

• koo-REER CHEH-kah nah-PO-lyoo

This is only an approximation, but it is a useful starting point.

Yes. Kurir can refer to different kinds of couriers, depending on context, such as:

• a package courier
• a delivery person
• a messenger

So in modern everyday use, it often means someone delivering parcels, food, or documents — not only traditional mail.

No. Serbian has more than one way to express outside.

For example:

• napolju — outside, outdoors
• vani — also outside, common in some regional varieties
• ispred — in front of, outside in front of something

So:

• Kurir čeka napolju. = The courier is waiting outside.
• Kurir čeka ispred zgrade. = The courier is waiting in front of the building.

Napolju is a very natural and common choice in this sentence.

Yes. Serbian often omits subject pronouns, but in this sentence the subject is a noun, not a pronoun, so whether you omit it depends on what you want to say.

You could say:

• Čeka napolju. — He/She is waiting outside.

But then the subject would only be understood from context.

If you specifically want to say that the courier is the one waiting, you keep kurir:

• Kurir čeka napolju.
