Position sculpture, replacing the pedestal (6)
I believe the answer is:
status
'position' is the definition.
(one's status or standing)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for status that I've seen before include "Standing position, perhaps" , "Position eg in society" , "Class" , "High social standing" , "Reputation" .)
