Fracas broke out without a muffler (5)
I believe the answer is:
scarf
'muffler' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for scarf that I've seen before include "Item of neckwear" , "Neck covering" , "Neck/head garment" , "bit of football memorabilia?" , "keep joints secure" .)
