Trade event with lots getting sold (7)
I believe the answer is:
auction
'trade event' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe there's an association between them I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for auction that I've seen before include "Where things are sold to the highest bidder" , "Public sale to highest bidders" , "Public sale by bid" , "Public sale to the highest bidder" , "Use caution at public sale" .)
