Q: In Michelle Obama’s memoir, Becoming, she uses this sentence to describe the sacrifices her parents made in raising her and her brother Craig: “We were their investment, me and Craig.” Surely that should be “Craig and I.”
A: Not necessarily. We would have written “Craig and I.” But the sentence as written is not incorrect. It’s informal, but not ungrammatical.
Here the compound (“me and Craig”) has no clear grammatical role. And as we wrote in 2016, a personal pronoun without a clear grammatical role—one that isn’t the subject or object of a sentence—is generally in the objective case.
In our previous post, we quoted the linguist Arnold Zwicky—the basic rule is “nominative for subjects of finite clauses, accusative otherwise.” In other words, when the pronoun has no distinctly defined role, the default choice is “me,” not “I.”
The Merriam-Webster Online Dictionary has this usage note: “I is now chiefly used as the subject of an immediately following verb. Me occurs in every other position.” The examples given include “Me too” … “You’re as big as me” … “It’s me” … “Who, me?”
“Almost all usage books recognize the legitimacy of me in these positions,” M-W says.
As we said, we think the compound “me and Craig” has no clear grammatical role. But digging deeper, we could interpret it as placed in apposition to (that is, as the equivalent of) the subject of the sentence: “we.” And technically, appositives should be in the same case, so the pronoun in apposition to “we” should be a subject pronoun: “I [not “me”] and Craig.”
That’s a legitimate argument, and if the author were aiming at a more formal style, she no doubt would have taken that route.
On the other hand, the same argument could be made against “Who, me?” Those two pronouns could be interpreted as appositives, but forcing them to match (“Whom, me?” or “Who, I?”) would be unnatural.
In short, the choice here is between formal and informal English (not “correct” versus “incorrect”), and the author chose the informal style.
By the way, as we wrote in 2012, the order in which the pronoun appears in a compound (as in “me and Craig” versus “Craig and me”) is irrelevant. There’s no grammatical rule that a first-person singular pronoun has to go last. Some people see a politeness issue here, but there’s no grammatical foundation for it.
That said, when the pronoun is “I,” it does seem to fall more naturally into the No. 2 slot. “Tom and I are going” seems to be a more natural word order than “I and Tom are going.” This is probably what’s responsible for the common (and erroneous) use of “I” when it’s clearly an object—as in “Want to come with Tom and I?”
