London borough behind minister's brief (9)
I believe the answer is:
revealing
'brief' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's an association between them I don't understand?
'london borough behind minister's' is the wordplay.
'london borough' becomes 'ealing' (I've seen this in another clue).
'behind' means one lot of letters go next to another.
'minister' becomes 'rev' (short for Reverend, a church minister).
'ealing' put after 'rev' is 'REVEALING'.
Can you help me to learn more?
(Other definitions for revealing that I've seen before include "Disclosing" , "Discovering" , "Giving away" , "to be telltale" , "Exposing" .)
