Hello, I just want to ask which one of these sentences is grammatically correct and why. Can you help me with this.?
'I hope her feels better soon'
'I hope she feels better soon'
Welcome to Using English, sophie.
I hope [that ] she feels better.
You don't have to use the "that" but it makes it clear that you are introducing a clause with it's own subject, and therefore you use the subject form of the pronoun, wihch is "she."
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
