Discard outhouse (4)
I believe the answer is:
shed
I believe this clue is a double definition.
'discard' is the first definition.
(thesaurus)
'outhouse' is the second definition.
(thesaurus)
(Other definitions for shed that I've seen before include "lost" , "Jettison" , "Take off in hut?" , "warehouse" , "something at the bottom of the garden?" .)
