People really do try, but it’s amazing what awful grammar they produce when they think they are getting it right. I even hear this error from cable newscasters , and especially from sportscasters.
“Ms. Grant gave he and she a nice wedding gift.”
Cringe!!!! The only way to prove how to fix this is to split up the happy couple.
“Ms. Grant gave him a nice wedding gift.”
“Ms. Grant gave her a nice wedding gift.”
“Ms. Grant gave him and her a nice wedding gift.”
Split up the pair or risk a grammar infidelity.
