Wooden construction discarded (4)
I believe the answer is:
shed
This clue might be a double definition.
'wooden construction' is the first definition.
'shed' can be an answer for 'construction' (shed is a kind of construction). I am not sure about the 'wooden' bit.
'discarded' is the second definition.
(I've seen this before)
Can you help me to learn more?
