This question already has an answer here:

I'm looking for an alternative to expressions of the form "X and I's Y", where X is a person/group and Y is a noun. Examples include:

  1. My partner and I's project was well-received.
  2. My family and I's trip went well.

I'm not even sure if the above two sentences are gramatically correct, but even if they are, they sound awful. What's a better way to say these sentences?

    The possessive of the pronoun I is my, not I's. – deadrat Aug 16 '16 at 4:06
  • @deadrat So could I say "My partner and my project was well-received?" – michaelsnowden Aug 16 '16 at 4:09
  • No, that sentence means that your partner was well-received and your project was well-received. You'll need to say, "My partner's and my project was well-received. " – deadrat Aug 16 '16 at 5:25
  • "My and my partner's project" would be better. – BillJ Aug 16 '16 at 6:34

I believe it would be "my partner's and my". It still makes sense if you remove "my partner's and" or "and my".

    But "John and Bill's cars", which is equally grammatical, and is used to show joint ownership, fails that test (though "John's and Bill's cars", again grammatical, passes). – Edwin Ashworth Aug 16 '16 at 20:09
