Tussle, scrap (5)
I believe the answer is:
fight
I believe this is a double definition.
'tussle' is the first definition.
(I know that tussle is a more specific form of fight)
'scrap' is the second definition.
(I know that scrap can be written as fight)
(Other definitions for fight that I've seen before include "Brawl; argue" , "Contest" , "Contend" , "Bundle" , "Scrap" .)
