Translation: Co robisz w weekend?

Is "na weekend" totally wrong?

[immery]

not totally wrong, I've heard Poles say this (also na weekendzie/łikeńdzie), but not correct either. Also may be misunderstood, na weekend means "for weekend", Like a homework for weekend, ( how dare they give it?) or a weekend trip. I might think you mean what I am preparing for weekend.

What is the difference between "w" and "we"?

[immery]

no difference. only we say "we" when "w" would be too hard to pronounce.
