Ako vidiš išta, pozovi me.

Ako means if.

It introduces a condition:

• Ako vidiš išta = If you see anything
• pozovi me = call me

So the whole sentence has the structure If X, then do Y.

Serbian usually does not need subject pronouns like I, you, he, etc., because the verb ending already shows who the subject is.

Here:

• vidiš = you see
• pozovi = you call / call!

So the you is already built into the verb forms.

You could add ti for emphasis, but it is normally left out:

• Ako ti vidiš išta, pozovi me.

That sounds more emphatic or contrastive, not neutral.

Vidiš is the 2nd person singular form, so it means you see.

It comes from videti / vidjeti (to see).

In this sentence, it appears in a clause with ako (if), where Serbian commonly uses the present-tense form to talk about a future condition:

• Ako vidiš... = If you see...

So even though the form looks like present tense, the meaning is really conditional/future-oriented in context.

Išta means anything or anything at all.

It is very common in contexts like:

• questions
• negatives
• conditions
• doubtful or hypothetical situations

Since this sentence is conditional (if you see...), išta fits well.

Compare:

• Ako vidiš išta, pozovi me. = If you see anything at all, call me.
• Ako vidiš nešto, pozovi me. = If you see something, call me.

Both can work, but išta sounds more like anything whatsoever, while nešto is more like something.

Not exactly.

Išta often appears in non-affirmative environments, especially:

• Da li vidiš išta? = Do you see anything?
• Ne vidim išta is generally not natural; you would normally say Ne vidim ništa = I don’t see anything
• Ako vidiš išta... = If you see anything...

So išta is not just a direct one-word replacement for English anything in every sentence. It works especially well in conditional or interrogative contexts.

A closely related word is ništa = nothing.

Pozovi is the imperative form meaning call!

It comes from pozvati (to call, perfective).

So:

• pozovi me = call me

Because it is imperative, the speaker is giving an instruction or request.

This is mainly about aspect.

• pozvati / pozovi is perfective
• zvati / zovi is imperfective

In commands, Serbian often uses the perfective verb when the idea is do this once / complete this action:

• Pozovi me = Call me / Give me a call

By contrast, zovi me can sound more like:

• Call me repeatedly
• Keep calling me
• or in some contexts simply a less bounded action

For a single completed action after some condition is met, pozovi me is very natural.

Me is the short unstressed form of I/me, used here as the direct object: call me.

Compare:

• ja = I (subject form)
• mene = me (full/emphatic form)
• me = me (short clitic form)

So:

• Pozovi me. = neutral, normal = Call me.
• Pozovi mene. = more emphatic = Call me (not someone else)

In ordinary speech, me is the expected form here.

Because me is a short clitic pronoun, and after an affirmative imperative it normally follows the verb:

• Pozovi me.
• Reci mi.
• Daj mu.

So pozovi me is the standard order.

The comma separates the conditional clause from the main clause.

• Ako vidiš išta = the condition
• pozovi me = the main instruction

When the if-clause comes first, Serbian normally uses a comma before the main clause.

This is similar to English:

• If you see anything, call me.

Yes. A very common alternative is:

• Pozovi me ako vidiš išta.

This means the same thing: Call me if you see anything.

The difference is mostly about focus and rhythm:

• Ako vidiš išta, pozovi me. puts the condition first
• Pozovi me ako vidiš išta. puts the instruction first

Both are natural.

Yes, it is understandable and natural.

That said, many speakers in everyday conversation might also say:

• Ako nešto vidiš, pozovi me.

That version is also very common and may sound a bit more conversational in some contexts.

The version with išta adds a nuance of anything at all, so it can feel slightly stronger or broader.

A simple English-friendly approximation is:

• Ako ≈ AH-koh
• vidiš ≈ VEE-deesh
• išta ≈ EESH-tah
• pozovi ≈ poh-ZOH-vee
• me ≈ meh

A few sound notes:

• š sounds like sh in ship
• ž sounds like s in measure
• č and ć are different Serbian sounds, though they do not appear in this sentence

So the whole sentence is roughly:

AH-koh VEE-deesh EESH-tah, poh-ZOH-vee meh.

Yes. That is a very helpful literal translation.

Because of išta, the sentence can carry the nuance:

• If you see anything at all, call me

That may capture the Serbian wording better than the simpler English If you see anything, call me, although both are correct translations.
