Questions & Answers about Завтра я испеку пирог для друга.
Because испечь is a perfective verb, and perfective verbs form the future with a single word.
- испечь = to bake, to bake completely, to finish baking
- я испеку = I will bake
This is different from imperfective verbs, which use буду + infinitive for the future:
- я буду печь = I will be baking / I will bake (with focus on the process)
- я испеку = I will bake it and complete it
So in this sentence, испеку emphasizes a completed result: the pie will get baked.
The infinitive is испечь.
This verb is a little irregular, so the future forms do not look exactly like the infinitive. That is normal for some common Russian verbs.
A few forms are:
- я испеку
- ты испечёшь
- он/она испечёт
- мы испечём
- вы испечёте
- они испекут
So испеку is simply the 1st person singular future form of испечь.
