Again dares to upset all of you (7)
I believe the answer is:
readers
'again dares to upset all of you' is the definition.
I can't judge whether this defines the answer.
'again dares to upset' is the wordplay.
'again' becomes 're' ().
'to upset' indicates an anagram.
'dares' anagrammed gives 'aders'.
're'+'aders'='READERS'
Can you help me to learn more?
(Other definitions for readers that I've seen before include "Consumers of the written word" , "Student textbooks" , "Bookish people" , "Perusers of the written word" , "Book users" .)
