Quick Latin Translation, please help! Thanks....

Have you heard of declensions? The declension you are looking for is genitive. It's in both plural and singular. If you look in a Latin dictionary, the genitive singular form is always displayed after the nominative (in this case, "wife", "uxor"). "uxoris" is the singular nominative, and "uxorum" is plural. Also, "meus" is "my", and can also be declensed. So "My wife's wife" is "mei uxoris uxor".

Thanks!
Thank you, in the words of my boss: you da man (or women i guess)!
