Exile unconscious in front of shed (7)
I believe the answer is:
outcast
'exile' is the definition.
(outcast can mean an exile from somewhere)
'unconscious in front of shed' is the wordplay.
'unconscious' becomes 'out' (similar in meaning).
'in front of' means one lot of letters go next to another.
'shed' becomes 'cast' (I've seen this in another clue).
'out'+'cast'='OUTCAST'
(Other definitions for outcast that I've seen before include "Role of Ishmael" , "one sent to Coventry" , "'Person excluded from society, a pariah (7)'" , "Displaced person" , "Derelict" .)
