Figure to snoop around for what’s secret (5)
I believe the answer is:
privy
'what's secret' is the definition.
('privy' can be a synonym of 'secret')
'figure to snoop around' is the wordplay.
'figure' becomes 'rivy' (I am not sure about this - if you are sure you should believe this answer much more).
'to' says to put letters next to each other (I've seen this in other clues).
'snoop' becomes 'spy' ('spy' can be a synonym of 'snoop').
'around' indicates the central letters.
The middle of 'spy' is 'p'.
'rivy' put after 'p' is 'PRIVY'.
'for' is the link.
Can you help me to learn more?
(Other definitions for privy that I've seen before include "John" , "Outside lavatory" , "Aware of" , "Admitted (to secrets)" , "sort of councillor" .)
