"Babcia mówi o swoich siostrach."

Translation: Grandma is talking about her sisters.

[Luke_5.1991]

Is "swoich" reserved for the subject of the sentence? If so, then it's just like Norwegian!

[Adiaphor]

Yep, just like norsk, when the object is singular it is like norsk too: ...o swoim bracie - ...om broren sin ...o swojej siostrze - ...om søstera si ...o swoim dziecku - ...om barnet sitt

[Nico515253]

Can we have 'talks' or must it be 'is talking'? If it were 'often talks about' (quite likely) is there a different verb? Thanks.

[Jellei]

It could be "mawia", but "mówi" is also a perfectly good translation. "talks" is accepted.

[zuza_245]

There is also a verb "opowiadać", which means to tell or talk about sth/sb.
Sentence with this verb would be: "Babcia opowiada o swoich siostrach".

[Jellei]

Makes sense, added.

[Matthew62991]

Sorry but why is grandmother wrong now?

[Jellei]

It's accepted. Perhaps you made a typo somewhere, then you got a correction which says "grandma". That doesn't mean that "grandmother" was the problem.

[Tim62192]

Is there any reason we can't have "speaking about" here?

[Jellei]

We can, it's accepted, it should have worked.

[megmccaliano]

Can I say, "My grandma is talking about her sisters"?

[Jellei]

On one hand, it's not that clear because there's no "I" or "my" nowhere in this sentence, but we can say that it's most likely the speaker's grandma. Alright, added.
