Journalists' boss rioted madly (6)
I believe the answer is:
editor
'journalists' boss' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'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 "Cudlipp, for one" , "One prepares a work for publication" , "Triode (anag.)" , "Top journalist" , "Senior publisher" .)
