How should I create possessives (for joined and separate ownerships) if each individual isn't a noun but a pronoun?
Knowing that: Peter and Dave's car means Peter and Dave own one car. And that Peter's and Dave's cars means Peter has a car and Dave has a car. (https://grammar.yourdictionary.com/parts-of-speech/nouns/possessive-nouns.html)
So now, how do I use the possessive if I want to include pronouns such as "your", "mine", "her", "their" and "his"?
When I want to make it clear that it's joined ownership, for example:
- If Dave and I both own the same car, how should I write? --> "Dave and my car", "Me and Dave's car" or "my and dave's car" or whatever option(s) is/are correct?
- If she and I both own the same cat, how should I write? --> "her and my cat" or whatever option(s) is/are correct?
But when I want to make it clear that it's separate ownership:
- If Dave and I each have a car of our own, how should I write? --> "Dave's and my cars" or "mine and dave's cars" or whatever option(s) is/are correct?
- If she and I each have a cat of our own, how should I write? --> "hers and my cats" or "mine and her cats" or whatever option(s) is/are correct?
Thank you for your help.
