This sentence is taken from L. G. Alexander's LONGMAN ENGLISH GRAMMAR: (from 11.15 of the book)
He can't have told you anything I don't already know.
I wonder why Alexander doesn't use 'yet' but 'already' in this negative sentence.
Could I ask native English teachers to help me?
Thank you very much.
It is because he already knows more than the person referred to.
