Confused scuffle (5)
I believe the answer is:
melee
'confused scuffle' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for melee that I've seen before include "Noisy riotous fight" , "Confused conflict, affray" , "Fracas" , "Affray; muddled group" , "Scrimmage" .)
