When should I use a subjective pronoun, and when an objective pronoun after "then"(THAN not THEN) in comparative sentences?
He was taller than she (was?)
He was taller than her
I think you could you both ways, the second one is more common.
You would have to use Subject pronouns to avoid vagueness as in :" I know him better than her" _ " I know him better than SHE does" ( different meaning).
