Is one wrong to make a racket? (5)
I believe the answer is:
noise
'make a racket?' is the definition.
(thesaurus)
'is one wrong' is the wordplay.
'wrong' is an anagram indicator.
'is'+'one'='isone'
'isone' is an anagram of 'NOISE'.
'to' acts as a link.
(Other definitions for noise that I've seen before include "interference" , "Excessive sound" , "Uproar" , "Loud sound; bruit" , "Unwelcome sound" .)
