Chief rioted in a new way (6)
I believe the answer is:
editor
'chief' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'rioted in a new way' is the wordplay.
'in a new way' is an anagram indicator.
'rioted' with letters rearranged gives 'EDITOR'.
Can you help me to learn more?
(Other definitions for editor that I've seen before include "One is in charge of publication" , "Director of newspaper" , "Do tire out the newspaper head" , "Person who revises and prepares for publication" , "Press fellow" .)
