Characters in impoverished geopolitics create a border solution (5)
I believe the answer is:
hedge
'a border solution' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'characters in impoverished geopolitics create' is the wordplay.
'characters in' says the answer is hidden in the clue.
'HEDGE' can be found hidden inside 'impoverished geopolitics create'.
Can you help me to learn more?
(Other definitions for hedge that I've seen before include "Prevaricate; boundary" , "Financial contract" , "Shrub boundary fence" , "avoid making commitments" , "Windbreak" .)
