In my English composition, I wrote the phrase "... my sister and I's favorite CD ..." According to my word processor's spell check there should not be an 's after I.

Question

Can 's be used after I? If not how would I show possession in the above phrase?

Answer 1

Use "my" to show possession. Note the apostrophe "s" after "sister."

My sister's and my favorite . . .

Answer 2

Okay. Thank you!

Answer 3

You're welcome.
