"Pomogła nam sprzątać dom."

Translation: She helped us clean the house.

[Pasteten]

There is a missing "to" before clean, or rather use "cleaning".

[Jellei]

I'm pretty sure that the sentence is correct, and "to" is not necessary.

[JerryMcCarthy99]

It is correct not to have a "to", but a "to" feels somehow better. If "cleaning" would be used, then the sentence would need to be something like "She helped us with cleaning the house".

[DidierCol]

Why "she" and not "he"? There are not here "ona"...

[Zkamin]

Past tense always has male/female different forms. Pomógł for "on" pomogła for "ona"

[ijbrito]

oh god

[patrisallegro]

thanks!

[zickovski]

Because 'ona pomogła' is feminine version of helped, for him it should be 'on pomógł'.

[Kendra800150]

So when the helping verb is perfective, as here, does it matter whether the infinitive is imperfective sprzątać or perfective posprzątać?

[Jellei]

Well... "posprzątać" means that the house was clean when we finished, "sprzątać" doesn't mention anything about that - maybe we had such a mess that after a few hours of hard work it is definitely better, but still far from being clean ;)

And "pomogła" just states that on one occasion she helped us with that.

[SandyTidwe]

"She helped us clean our home" was not accepted. Why?

[JerryMcCarthy99]

Possibly because "house" and "home" are not exactly interchangeable, although I think it might be alright in this sentence.

[Jellei]

OK, added "home".

[Walkinthedog]

Would you accept, clean house. That's the way we use that term.

[Jellei]

OK, added.
