Buffoon Farage not mature about Brussels' rules primarily (7)
I believe the answer is:
farceur
'buffoon' is the definition.
Both the definition and answer are singular nouns.
Perhaps they are linked in a way I don't understand?
'farage not mature about brussels' rules primarily' is the wordplay.
'not' suggests deleting specific letters.
'mature' becomes 'age' (synonyms).
'about' indicates putting letters inside.
'brussels'' becomes 'EU' (European Parliament is based in Brussels).
'rules primarily' becomes 'cr' (I can't justify this - if you can you should believe this answer much more).
'farage' with 'age' taken away is 'far'.
'eu' placed inside 'cr' is 'ceur'.
'far'+'ceur'='FARCEUR'
Can you help me to learn more?
(Other definitions for farceur that I've seen before include "Comedian" , "Person who writes comedies -- fur care (anag)" , "playmaker" .)
