Party on Silver Street turned around (4)
I believe the answer is:
stag
'party' is the definition.
(stag party is a kind of party)
'silver street turned around' is the wordplay.
I cannot really understand how this works, but
'silver' could be 'ag' (Ag is the chemical symbol for silver) and 'ag' is found within the answer.
'street' could be 'st' (abbreviation) and 'st' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'on' acts as a link.
Can you help me to learn more?
(Other definitions for stag that I've seen before include "Share speculator" , "Stockmarket operator gambling on a quick profit" , "This party is for men only" , "Stock Exchange speculator standing" , "speculator wanting quick profit" .)
