Questions & Answers about Ona će platiti haljinu u prodavnici danas.
In Serbian, the future tense is often formed with the short form of hteti (ću, ćeš, će, ćemo, ćete, će) plus the infinitive or a da + present construction.
Here, ona će platiti means she will pay.
With a full subject like ona, the clitic će usually comes in the second position of the sentence or clause:
- Ona će platiti...
You may also see:
- Platiće... = She will pay...
That attached form is also correct, but when the subject is stated explicitly, ona će platiti is very common and natural.
Platiti is a perfective verb, while plaćati is its imperfective partner.
- platiti = to pay, seen as a completed action
- plaćati = to be paying, to pay repeatedly, to pay in general
In this sentence, the speaker is talking about one future completed act of payment, so platiti is the natural choice:
- Ona će platiti haljinu... = She will pay for the dress
If you used plaćati, it would sound more like an ongoing, habitual, or repeated action, depending on context.
