Scarf returned without a fight (6)
I believe the answer is:
fracas
'fight' is the definition.
(I've seen this before)
'scarf returned without a' is the wordplay.
'returned' is a reversal indicator.
'without' indicates putting letters inside ('without' can be similar in meaning to 'outside').
'scarf' reversed gives 'fracs'.
'fracs' going around 'a' is 'FRACAS'.
(Other definitions for fracas that I've seen before include "Affray" , "Brawl, disturbance" , "Melee" , "Uproar - brawl" , "Dust-up" .)
