Prize put up in storage unit (6)
I believe the answer is:
drawer
'storage unit' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'prize put up' is the wordplay.
'prize' becomes 'reward' (a prize may be given as a reward).
'put up' shows that the letters should be reversed in order.
'reward' back-to-front is 'DRAWER'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for drawer that I've seen before include "Part of bureau" , "One who writes cheque; storage box" , "Part of chest" , "Sliding part in a piece of furniture" , "Sliding compartment in a chest" .)
