Retail outlet quiet before work (4)
I believe the answer is:
shop
'retail outlet' is the definition.
(I've seen this before)
'quiet before work' is the wordplay.
'quiet' becomes 'sh'.
'before' says to put letters next to each other.
'work' becomes 'op' (abbreviation for opus).
'sh'+'op'='SHOP'
(Other definitions for shop that I've seen before include "Where goods are bought and sold" , "Store, outlet" , "Retail outlet" , "Betray - place selling things" , "Be disloyal to" .)
