Somewhere before - antes de

Somewhere before - antes de
 

Would antes de be used in the following?
I have seen her somewhere before.
I heard him say that before.

thanksssssssss

Antes de is used if something follows before. (like before I knew you would translate: antes de conocerte...)

Well I would translate your sentences like this.......

I have seen her somewhere before.
-Yo la he visto antes en algún sitio.

I heard him say that before.
-Lo he escuchado decir eso antes.

:)

My attempt, I would like translate those sentences using the word antes de,


I have been in that place before than you.
He estado en ese lugar antes que tu.


Do you have toke my computer before.
Has tocado my compudora antes?

I have seen to her before on some place.
La he visto antes en algun lugar.


I want to say that the word Antes is mostly used when you are trying to say something or any sentece in past, I hope my examples to be of useful for you.

thanks for info

I'm sorry by my mistakes you're welcome.

don't worry if you made mistakes I make them too :) you can learn from your mistakes too :)

Yes, I believe that, the important of this case is help to other persons.

My take on this:

I have seen her somewhere before.
La he visto antes en algún lugar.

I heard him say that before.
Lo he escuchado decir eso antes.

my two cents
I have seen her somewhere before.
La he visto antes en algún sitio.
I heard him say that before.
Le oí decir eso antes.
Le escuché decir eso antes.
Eso ya se lo había oído yo.

"antes de" is more for something that happens before an "more-or-less" establissed event.
"antes de que amanezca" "antes de la revolución" "antes de empezar con la comida"
"antes de que os marchéis" "antes de morirme" "antes de que el coche se estropee"
