Morsel or cancel (5)
I believe the answer is:
scrap
I believe this clue is a double definition.
'morsel' is the first definition.
(I've seen this in another clue)
'cancel' is the second definition.
(I've seen this before)
(Other definitions for scrap that I've seen before include "Drop" , "A fragment or an informal fight" , "Discard; a bit" , "argument" , "Discard; fight" .)
