she had spoken to him before he went home. czy she spoke to him before he
went go home . ktore jest poprawne i dlaczego

[sweet_auburn]

to speak to sth/sbd expresses your ability to do so.
Usually we talk to people. (eventually, you may want to say I speak
with........., but still)
And the first one is correct. She had talked to him before he went home.
Dlaczego? Bo wyraznie zaznaczasz kolejnosc wydarzen w przeszlosci. Najpierw z
nim romawiala, a potem poszedl do domu.

I think both are correct. You would use Past Perfect when you really want to
make a point that something occurred before another action in the past. In the
second sentence, you are just stating the facts and grammatically such
sentences are still fine. It all depends on your perception of those events and
how important it is to you to make the specific time distinction.
