Wooden construction discarded (4)
I believe the answer is:
shed
This clue could be a double definition.
'wooden construction' is the first definition.
'shed' can be an answer for 'construction' (shed is a kind of construction). I'm not certain of the 'wooden' bit.
'discarded' is the second definition.
(I've seen this in other clues)
Can you help me to learn more?
(Other definitions for shed that I've seen before include "Hut - throw off - Guardian cryptic crossword setter" , "Lose as trees do leaves" , "Kind of hut - discard it" , "Drop; outhouse" , "Outhouse -- cast" .)
