Questions & Answers about Ocena će pomoći kupcu.
Će is the 3rd person singular future-tense auxiliary, from the verb hteti (to want), which is also used to form the future.
So:
- ocena = rating / grade / evaluation
- će pomoći = will help
- kupcu = to the customer / buyer
So će is the part that gives the sentence the meaning will.
Because the standard Serbian future tense is commonly formed with:
- a clitic form of hteti (ću, ćeš, će, ćemo, ćete, će)
- plus the infinitive
So here:
- će pomoći = will help
You do not use a normal present-tense form after bare će in this structure.
A different, more colloquial pattern is:
- će da + present
- for example: Ocena će da pomogne kupcu.
But in standard, textbook-style Serbian, Ocena će pomoći kupcu. is a very normal way to say it.
