"Mama posprzątała mój pokój."

Translation: Mom has cleaned my room.

[Filavero]

Does this require the "up" in English?

[Viersch]

No.

[Darth_Elven]

Sounds a little bit strange without "up"

[NotLolpan]

Not really, to be fair.

[dundevanma1]

I used 'tidy' which was marked as incorrect. Was surprised.

[Jellei]

Added "tidied".

[aleksy8]

Surely it should be my mom and not just mom, there needs to be an article befor the work mom

[eannaoc]

Not necessarily, usually in English if someone is referring to their own mother they just say "mom/mum/mam", especially when talking to another family member

[Jellei]

"My mom" is also accepted.

[Fidchell]

So "posprzątać" is supposed to be the perfective of sprzątać, right? Because in internet I also found that "sprzątnać" is the perfect of "sprzątać". Is there a difference between the two perfective forms? Or is it just the same meaning and same usage?

[Jellei]

I think both could work here, but 'sprzątnąć' can be also used to refer to some object which has to be put in its right place.

thanks! :)
