Translation:But she is married.
how do I know from the sentence that it is a she and not a he?
In czech? When is it she , you use vdaná;when is it he, you use ženatý
Even if he is married to a man and she is married to a woman?
The other case yes, the first one no, that would be nonsence "ženatý=má ženu=has a wife"
As ValaCZE says, but the grammar difference can be simply seen in the -á for her and -ý for him. ;-)
