"Do you know his cousin's wife?"

Translation: Znáš ženu jeho bratrance?

[venik212]

For wife, DL sometimes uses žena and sometimes manželka. How can we tell which one is appropriate in a given situation?

[VladaFu]

Both are appropriate in any social situation.

[ali940239]

Znáš ženu svého bratrance....... může být?

[VladaFu]

No, svůj refers to the subject of the sentence so that would mean: Do you know the wife of your cousin?
