I want to talk about a specific woman. She is the wife of one of my cousins. So I have several cousins, but not each of them has a wife, and those who have one obviously only have one.
Can I say "one of my cousins' wife"? In which "one of" refers to "one cousin amongst the group of several men who are my cousins"?
If I pronounce this sentence, people can hear "one of my cousin's wife", and then there is a mistake because I say "wife" instead of "wives", as they understand that one cousin has several wives.
So could I write "one of my cousins' wife" or "one of my cousins's wife"? Or should I just give up and switch to "the wife of one of my cousins"? I can say it differently but I'm very interested in knowing what could be possible. Thank you!
