Questions & Answers about Sem você me avisar, eu não sei se devo puxar ou empurrar a porta.
Why does the sentence start with Sem você me avisar?
Sem means without, and it is followed here by an infinitive phrase: você me avisar = you telling/warning me.
So:
- sem = without
- você me avisar = you informing me
Together, Sem você me avisar literally means Without you telling me.
This is a very natural way in Portuguese to express without someone doing something.
Why is it você me avisar and not just me avisar?
Because você is the subject of avisar.
Compare:
- Sem me avisar = Without telling me
(it doesn’t clearly say who is doing the telling) - Sem você me avisar = Without you telling me
So você is included to make it explicit that you are the one who should warn/inform me.
