I’ve seen the usage “between you and I” many times in print, including in places that should have had the benefit of professional editing.
Is this accepted usage now? What determines whether a phrase that was once grammatically incorrect is now okay?
(I confess that “between you and I” grates on me. After all, no one says “just between we.” But “to boldly go” sounds okay to me. I had a friend once defend the incorrectness of split infinitives in part by saying that “to be or to not be” sounds wrong. After thinking about it, I realized that “to be or to not-be” may actually be better than how WS put it.)
I know it isn’t your main question but split infinitives are not grammatically wrong although they are often stylistically questionable. There has never been a true rule against them in English despite what your schoolteachers claimed. It is simply easier to say that it is a rule in the early grades rather than try to cover the intricacies of the myriad of exceptions and counterexamples.
“Between you and I” is simply grammatically incorrect and always has been.
"So now we can move on to “Between You and I” and figure out why it’s wrong.
Between is a preposition, just as on, above, over, and of are prepositions. Because prepositions usually either describe a relationship, or show possession, they don’t act alone; they often answer questions like Where? and When? For example, if I said, “Keep that secret between you and me,” between describes where the secret is to be kept. If I said, “I’ll tell you the secret on July 5,” on describes when the secret will be revealed."
“Between you and I” is not correct. The last word is the object of a preposition and should be “me”. People who write that are mistakenly getting confused with something like “he is richer than you and I,” where “I” is correct.
As Baron Greenback insinuates, it might become correct sometime in the future through repeated misuse, but it ain’t there yet.
I get what you’re saying, but I think “correct” and “accepted” implies some type of style guide. I could say to you “me want now dinner” and you’d know what I meant, but you can’t say that is correct even though we’re just communicating.
You and me both (you and I both?). I had an editor who drilled the difference into me several years ago. Up until fairly recently, I valiantly changed “may” to “can” everywhere until finally giving up.
