A place in the sin bin (6)
I believe the answer is:
office
'a place' is the definition.
(synonyms)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for office that I've seen before include "Subsidiary" , "Position of authority" , "Workroom" , "Professional or clerical duties are performed here" , "Place for administrative business" .)
