Questions & Answers about Zanim uruchomię silnik, muszę ustawić fotel.

Why does the sentence start with zanim?

Zanim means before in the sense of before something happens / before I do something.

It introduces a subordinate clause:

• Zanim uruchomię silnik = Before I start the engine

So the structure is:

• zanim + clause
• then the main clause: muszę ustawić fotel

This is very common in Polish:

• Zanim wyjdę, zamknę okno. = Before I leave, I’ll close the window.
• Zanim usiądę, zdejmę płaszcz. = Before I sit down, I’ll take off my coat.

Why is it uruchomię, not something like a normal future tense?

Uruchomię is the 1st person singular form of the perfective verb uruchomić.

In Polish, perfective verbs do not have a separate simple future form. Their present-tense-looking forms usually refer to the future.

So:

• uruchamiam = I am starting / I start (imperfective, present)
• uruchomię = I will start (perfective, future meaning)

That is why zanim uruchomię silnik means before I start the engine, not before I am starting the engine.
