Here's a breakdown:
* Czy - means "whether" or "if"
* chcesz - means "you want"
* wyjść - means "to go out"
* za - means "for"
* mnie - means "me"
So, the entire phrase translates to "Whether you want to go out for me?" which is a common way of asking someone to marry you in Polish.
Here are some other ways to say it:
* Czy chcesz zostać moją żoną? - "Do you want to become my wife?" (more formal)
* Czy chcesz wziąć ze mną ślub? - "Do you want to marry me?" (more literal)
* Chcesz być moją żoną? - "Do you want to be my wife?" (less formal)
Remember to adjust your tone and formality to the situation and your relationship with the person you're asking. Good luck!
