Fights; fragments (6)
I believe the answer is:
scraps
I believe this clue is a double definition.
'fights' is the first definition.
(I've seen this in another clue)
'fragments' is the second definition.
(I know this)
(Other definitions for scraps that I've seen before include "useless bits" , "Fragments left over (6)" , "Pieces of uneaten food" , "Fragments for fights" , "thrown away?" .)
