Questions & Answers about Если код подтверждения не придёт, я перезвоню в банк.

Why is Russian using the future придёт after если? In English we say if the code doesn't arrive, not if the code won't arrive.

This is a normal difference between English and Russian.

In Russian, when you talk about a real future condition, you usually use a future form:

• Если код подтверждения не придёт, я перезвоню в банк.

Russian does not avoid the future after если the way English does. So не придёт is exactly what you expect here.

If you used не приходит, that would sound like a general or repeated situation, something more like if the code doesn't usually come / isn't coming, not this one future case.

Why is it придёт and not будет приходить?

Because прийти is a perfective verb, and perfective verbs form the future with a single word:

• приду
• придёшь
• придёт

Perfective here shows one completed event: the code either arrives or it does not.

Будет приходить is an imperfective future and usually suggests an ongoing, repeated, or process-like action, which does not fit a one-time confirmation code very well.

So:

• придёт = will arrive once
• будет приходить = will be coming / will keep coming

What verb is from? Why does it look so different from ?
