Vagabond unconscious by shed (7)
I believe the answer is:
outcast
'vagabond' is the definition.
(I've seen this before)
'unconscious by shed' is the wordplay.
'unconscious' becomes 'out' (similar in meaning).
'by' is a charade indicator (letters next to each other).
'shed' becomes 'cast' (I've seen this before).
'out'+'cast'='OUTCAST'
(Other definitions for outcast that I've seen before include "One rejected by group" , "One banished from society" , "'Person excluded from society, a pariah (7)'" , "Person rejected by a group or society" , "vagabond" .)
