Commotion about a scarf (6)
I believe the answer is:
fracas
'commotion' is the definition.
(thesaurus)
'about a scarf' is the wordplay.
'about' indicates an anagram.
'a'+'scarf'='ascarf'
'ascarf' anagrammed gives 'FRACAS'.
(Other definitions for fracas that I've seen before include "Noisy quarrel or disturbance" , "Fight" , "Bust-up" , "Brawl, disturbance" , "A scarf (anag)" .)
