You and I or you and me?
If you struggle to remember whether to use I or me in sentences, here’s an easy way of working it out: Repeat the sentence to yourself as if you were the only person in it.
Here are two examples:-
Original sentence: This would be a great present for Graham and (I or me).
Sentence with only you: This would be a great present for me.
Correct complete sentence: This would be a great present for Graham and me.
Original sentence: It would be lovely if Fiona and (I or me) could join you.
Sentence with only you: It would be lovely if I could join you.
Correct complete sentence: It would be lovely if Fiona and I could join you.
For those of you who may be interested in the grammar behind it, I and me are personal pronouns. I is used when the person is the subject of the sentence, me when the person is the object.
