Dear Alan,
Thank you so much for your quick reply. May I have one more question in connection with this?
Which ending is correct?
He is cleverer than me.
He is cleverer than I.
He is clevere than I am.
Your dog is cleverer than my dog.
Your dog is celevrer than my dog is.
Your dog is clevere than mine.
Your dog is clevere than mine is.
Thanks a lot!
bye
Liza
