Riot ideal material for press comment (9)
I believe the answer is:
editorial
'press comment' is the definition.
'editorial' can be an answer for 'comment' (thesaurus). I am not certain of the 'press' bit.
'riot ideal material' is the wordplay.
'material' indicates an anagram (the letters provide the material for a new word).
'riot'+'ideal'='riotideal'
'riotideal' anagrammed gives 'EDITORIAL'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for editorial that I've seen before include "Chief newspaper article" , "considered view on paper" , "leader, perhaps" , "Article that states a newspaper's opinion" , "Article giving a newspaper's opinion" .)
