He has nothing new to offer (7,6)
I believe the answer is:
antique dealer
'offer' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'he has nothing new' is the wordplay.
I cannot quite understand how this works, but
'he' could be 'eal' and 'eal' is found in the answer.
'new' could be 'n' (common abbreviation eg NT for New Testament) and 'n' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Another definition for antique dealer that I've seen is " Buyer and seller of bygones".)
