Fight in shed (5)
I believe the answer is:
scrap
I believe this is a double definition.
'fight' is the first definition.
(thesaurus)
'shed' is the second definition.
(thesaurus)
'in' acts as a link.
(Other definitions for scrap that I've seen before include "Waste metal or informal fight" , "Waste metal or slang fight" , "Junk; altercation" , "boxing match?" , "Get rid of" .)
