Questions & Answers about W sobotę ona odkurza dywan, a ja myję podłogę.
In Polish, days of the week after w (in / on) are usually in the accusative case when you mean “on [this/that] Saturday” or a specific Saturday.
- sobota – nominative (dictionary form)
- sobotę – accusative
So:
- w sobotę = on Saturday
- w niedzielę = on Sunday
- w poniedziałek = on Monday
The preposition w + a point in time like a day → accusative case.
That’s why you say w sobotę, not w sobota.
Yes, you can. Polish is a “pro‑drop” language: subject pronouns are often omitted because verb endings already show who is doing the action.
- odkurza – 3rd person singular (he/she/it)
- myję – 1st person singular (I)
So grammatically you can say:
- W sobotę odkurza dywan, a myję podłogę.
However, adding ona and ja can:
- make the contrast clearer: ona vs ja
- add emphasis: She vacuums the carpet, and I wash the floor.
Both versions are correct; the original sounds slightly more explicit and emphatic.
