Writer, Italian heretic who brooks no opposition? (13)
I believe the answer is:
authoritarian
'writer italian heretic who brooks no opposition?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'writer italian heretic' is the wordplay.
'writer' becomes 'author' (synonyms).
'italian' becomes 'it' (abbreviation for Italian).
'heretic' becomes 'arian' (Arianism is a form of heresy).
'author'+'it'+'arian'='AUTHORITARIAN'
Can you help me to learn more?
(Other definitions for authoritarian that I've seen before include "Enforcing strict obedience" , "Oppressively strict" , "despot" , "Domineering" , "Dictatorial" .)
