Good morning. Today on the TV news I heard some more wrong grammar usage. How many times do you hear, "for you and I" ? for is a preposition and therefore uses the demonstrative case for its subjects.
Nominative case pronouns: I, we, he, she, they, who...it, you
Demonstrative case pronouns: me, us, him, her them, whom.....it, you
Try saying this....This cake is for us. Or...This cake is for we. You know it would be us. So, you would say ....This cake is for you and me. Thanks for listening.
