Market shows disappointment (4)
I believe the answer is:
sell
This clue could be a double definition.
'market' is the first definition.
(I know that market is a kind of sell)
'disappointment' is the second 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?
'shows' acts as a link.
Can you help me to learn more?
(Other definitions for sell that I've seen before include "Betray" , "Market, vend" , "Dispose of for money" , "Exchange for cash" , "What shops do" .)
