Discern extremely rare jackets using a single pin in retail area (8,6)
I believe the answer is:
shopping centre
'retail area' is the definition.
The definition suggests a singular noun which matches the answer.
'discern extremely rare jackets using a single pin' is the wordplay.
'discern' becomes 'scent' (I can't explain this - if you can you should believe this answer much more).
'extremely' suggests removing the centre (only the extremes of the word are used).
'jackets' indicates putting letters inside.
'using a single pin' becomes 'hopping' (pins can mean someone's legs).
'rare' with its middle removed is 're'.
'scent'+'re'='scentre'
'scentre' going around 'hopping' is 'SHOPPING CENTRE'.
'in' is the link.
Can you help me to learn more?
(Other definitions for shopping centre that I've seen before include "Where there are many stores" , "Place with many retail outlets" , "Marketing complex" , "mall" .)
