Me or I? Choosing between these two pronouns is a struggle for some writers, including me. Too often writers insert I when the correct word is me. Why? Because the use of I sounds formal, almost stilted, therefore it must be correct, right? Sorry, but no. Formal and stilted does not equate to proper --- just ask the English Monarchy!
My personal Grammar Goddess taught me a quick trick for this one . . . simply remove the other proper noun and use what sounds natural. For example:
Can you take a picture of Sam and I?
Remove the proper noun Sam and you have: Can you take a picture of I.
Doesn’t sound right, and thus the proper phrasing should be: Can you take a picture of Sam and me?
Just one of the many simple tricks I have accumulated in my grammar files. Hope it helps, and have fun writing!
P.S. Don’t be afraid to use myself either! It is a reflexive pronoun that that should almost always be used in conjunction with the pronoun I. It is great way to express emphasis; but, be careful. Most seasoned editors will reject if used as a replacement for me.
