Broken sculpture (4)
I believe the answer is:
bust
This clue is a double definition.
'broken' is the first definition.
(bust can mean broken)
'sculpture' is the second definition.
(bust is a kind of sculpture)
(Other definitions for bust that I've seen before include "Sculpture of head and chest" , "Chest; bankrupt" , "Piece of sculpture - broken!" , "Financially ruined" , "Small statue" .)
