Governing, takes risks showing symbols of power (7)
I believe the answer is:
indices
'symbols of power' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Perhaps you can see a link between them that I can't see?
'governing takes risks' is the wordplay.
'governing' becomes 'in' (I can't justify this - if you can you should believe this answer much more).
'takes risks' becomes 'dices' (to dice is to gamble or take a risk).
'in'+'dices'='INDICES'
'showing' acts as a link.
Can you help me to learn more?
(Other definitions for indices that I've seen before include "Catalogues" , "Signs - fingers" , "Mathematical symbols denoting powers" , "Mathematical exponents" , "Files" .)
