Journalists' boss rioted madly (6)
I believe the answer is:
'journalists' boss' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'rioted madly' is the wordplay.
'madly' indicates an anagram.
'rioted' is an anagram of 'EDITOR'.
Can you help me to learn more?
(Other definitions for editor that I've seen before include "One who revises another's writing", "Do tire out the press person", "one in charge of 10 [PRESS GANG] ?", "Person who determines the final content of a text", "Redactor".)
