Questions & Answers about Večeras ću pozvati sestru telefonom.
Why is ću used here, and what tense is this?
Ću is the 1st person singular auxiliary used to form the future tense in Serbian.
In Večeras ću pozvati sestru telefonom, the pattern is:
- ću = I will
- pozvati = infinitive of the main verb, to call
So ću pozvati means I will call.
This is the usual way to form the future in standard Serbian:
- ja ću doći = I will come
- ti ćeš videti = you will see
- oni će otići = they will leave
Why is it pozvati, not zvati?
This is about verb aspect, which is very important in Serbian.
- zvati is imperfective
- pozvati is perfective
In this sentence, pozvati is used because the speaker is talking about one completed action in the future: making a call once, successfully, as a whole event.
A rough comparison:
- zvaću sestru can suggest I’ll be calling my sister / I’ll call my sister in a more ongoing or repeated sense, depending on context.
- pozvaću sestru / ću pozvati sestru suggests I’ll give my sister a call as a single completed act.
English often does not force this distinction, but Serbian usually does.
