One hopes to get a lot from offer to the German (6)
I believe the answer is:
bidder
'one hopes to get a lot' is the definition.
I can't judge whether this defines the answer.
'offer to the german' is the wordplay.
'offer' becomes 'bid' (bid is a kind of offer).
'to the german' becomes 'der' ('the' in German).
'bid'+'der'='BIDDER'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for bidder that I've seen before include "He offers to buy at auctions" , "Participate in an auction" , "One at auction" , "One offers" , "One makes an offer" .)
