For which to bid a high price? (3)
I believe the answer is:
lot
This might be a double definition.
'for which to bid' is the first definition.
The definition suggests a singular noun which matches the answer.
'a high price?' is the second definition.
The definition and answer can be both to do with ownership as well as being verbs in their base form.
Maybe you can see an association between them that I can't see?
Can you help me to learn more?
(Other definitions for lot that I've seen before include "Auction item, great deal" , "Fortune" , "Group of auction items" , "Great amount" , "He left his wife without a backward glance" .)
