Merchant of Venice, people repeatedly say ''Between whoever and I,'' which isn't right. You'd think Portia (beng the rich wench she is) would have known, I mean, it's not like her Father didn't have enough money to pay for her schooling.
A quick search of the text shows that the words "Between [noun] and I" only appears ONCE in the play and the words are spoken by Bassanio when he is reading Antonio's letter begging his friend to come see him before Shylock takes a pound of flesh out of him.
Ah, good ol'anti semitism in literature. One thing we could never accuse Shakespeare of was political correctness.
back tot he point, Portia never uses the phrase in the play. She does several times say "between [noun] and [noun]" but never uses the first person there.
But I will admit, that you are correct. When Antonio wrote the words "Between you and I" he was technically using improper grammar. And Antonia was supposed to be an educated merchant. However, if you replace the "I" with a "me" it doesn't sound as dramatic, so I would attribute this to Willy's sense of drama.
