Pratim pošiljku na telefonu.

In Serbian, the subject pronoun is often omitted because the verb ending already shows who is doing the action.

• pratim = I track / I am tracking

The -m ending tells you it is 1st person singular, so ja is not necessary.

You can say Ja pratim pošiljku na telefonu, but that usually adds emphasis, like:

• I’m the one tracking it.
• I am tracking it, not someone else.

So the version without ja is the normal, neutral one.

Pratim is the present tense, 1st person singular, of the verb pratiti.

So:

• pratiti = to follow, track
• pratim = I follow / I am following, I track / I am tracking

A useful thing to remember is that Serbian present tense often covers both English:

• I track
• I am tracking

The exact English translation depends on context.

Because pošiljku is the accusative singular form, used here for the direct object of the verb.

The base form is:

• pošiljka = shipment, package, consignment

But after a verb like pratim when it is the thing being tracked, Serbian uses the accusative:

• Pratim pošiljku. = I’m tracking the shipment.

This is a very common pattern with feminine nouns ending in -a:

• nominative: pošiljka
• accusative singular: pošiljku

Telefonu is in the locative singular.

That is because it comes after the preposition na, which here expresses location or the place where something is being done:

• na telefonu = on the phone

The noun changes like this:

• telefon = phone
• na telefonu = on the phone

So in this sentence:

• pošiljku = accusative, because it is the object
• telefonu = locative, because it follows na

Because Serbian normally uses na for things done on a device / on a screen / on a platform.

So na telefonu is the natural way to say:

• on the phone
• on my phone
• using my phone

If you said u telefonu, it would usually sound like inside the phone, which is not the intended meaning here.

This is similar to other common Serbian patterns such as:

• na računaru = on the computer
• na internetu = on the internet
• na ekranu = on the screen

In this sentence, it most naturally means on my phone or using a phone.

But yes, na telefonu can have other meanings in different contexts. For example, it can sometimes mean on the phone in the sense of being engaged with the phone.

Here, because the verb is pratim pošiljku (I’m tracking a shipment), the most natural interpretation is:

• I’m tracking the shipment on my phone

If the speaker wanted to make my explicit, they could say:

• Pratim pošiljku na svom telefonu.

That adds clarity or emphasis, but it is not required.

No, not usually.

Serbian often leaves out possessives like my, your, his, etc. when they are obvious from context, especially with personal items.

So:

• na telefonu often naturally means on my phone or on the phone, depending on context

If you want to be more explicit, you can say:

• na svom telefonu = on my own phone

That version is useful if you want contrast, for example:

• Pratim pošiljku na svom telefonu, ne na tvom.
• I’m tracking the shipment on my phone, not yours.

No, Serbian word order is fairly flexible.

Pratim pošiljku na telefonu is a neutral, natural order. But you could also say:

• Pošiljku pratim na telefonu.
• Na telefonu pratim pošiljku.

These versions are still grammatical, but they shift the focus a little:

• Pošiljku pratim... puts more emphasis on the shipment
• Na telefonu... puts more emphasis on the phone / device

So the original sentence is a good neutral default.

It can mean either, depending on context.

Serbian present tense is broader than English, so pratim can correspond to:

• I track
• I am tracking

In this sentence, most people would understand it as something currently happening or as a normal ongoing activity, such as checking shipment status on a phone.

Also, pratiti is an imperfective verb, which fits actions seen as ongoing, repeated, or in progress.

A few sounds in pošiljku are especially important:

• š sounds like sh in shoe
• lj is a single Serbian sound, not a normal English l + y sequence

A rough guide:

• po-šilj-ku

You can think of lj as somewhat similar to the lli in some pronunciations of million, though it is not exactly the same for every English speaker.

So pošiljku is roughly:

• po-SHEEL-kyoo, but with a softer lj sound before the k

This is only an approximation, but it helps.

Not exactly, though they can overlap.

• paket usually means a physical package / parcel
• pošiljka is broader and can mean shipment, dispatch, or mail item

So if you are tracking something through delivery or postal service, pošiljka is a very natural word.

In many real-life situations, both might be possible, but pošiljka sounds a bit more general and logistics-related.

Yes, it sounds natural and understandable.

A native speaker would easily understand:

• Pratim pošiljku na telefonu.

Depending on context, they might also say things like:

• Pratim pošiljku preko telefona.
• Pratim pošiljku na svom telefonu.
• Na telefonu pratim pošiljku.

But the original sentence is perfectly normal, especially if the idea is that someone is checking tracking information on their phone.
