"Ten muž často chodí do matčina bytu."

Translation: That man often goes to my mother's apartment.

[EinatAdar]

How do you know that it is my mother and not his mother?

[endless_sleeper]

It's kinda implied.

You would use something like '...do bytu jeho matky.' to stress that it's his mother. Otherwise, I would assume you talk about your own mother.

[EinatAdar]

Thanks for the explanation. Is this a general assumption, that the unspecified person is related to the speaker unless it's explicitely stated otherwise?

[endless_sleeper]

I'd say so.

[EinatAdar]

I see. Thanks!
