Questions & Answers about 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.
