Model that's still on display (9)
I believe the answer is:
mannequin
'model' is the definition.
(synonyms)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for mannequin that I've seen before include "fashion model" , "Life-size dummy for displaying clothes" , "Shop's dummy" , "Display dummy" , "Dummy figure" .)
