Comic that is beginning to ridicule councillor (6)
I believe the answer is:
vizier
'councillor' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'comic that is beginning to ridicule' is the wordplay.
'comic' becomes 'viz' (I am not sure about this - if you are sure you should believe this answer much more).
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'beginning to' suggests taking the first letters.
The initial letter of 'ridicule' is 'r'.
'viz'+'ie'+'r'='VIZIER'
Can you help me to learn more?
(Other definitions for vizier that I've seen before include "Sultan's chief minister" , "High officer in various Muslim states" , "High-ranking official in some Muslim countries" , "Former Muslim official" , "Turkish bigwig" .)
