Questions & Answers about Я выйду на минуту.
Because выйду comes from выйти, which is a perfective verb. In Russian, perfective verbs do not have a true present tense. Their “present-looking” forms actually refer to the future.
So:
- я выхожу = I am going out / I go out
- я выйду = I will go out / I’ll step out
Here, the speaker means a single, complete action: stepping out once.
The infinitive is выйти.
It is built from:
- идти = to go (on foot, in one direction)
- prefix вы- = out, outward
So выйти literally means to go out, to come out, or to step out.
In this sentence, it usually means something like to step out briefly.
