Minor fight (5)
I believe the answer is:
scrap
'minor fight' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for scrap that I've seen before include "Fragment or remnant" , "Dispense with - waste material" , "Small amount; fight" , "Carps (anag.)" , "Leftover; fight" .)
