Outflow takes me back to a country (9)
I believe the answer is:
emanation
'outflow' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'me back to a country' is the wordplay.
'back' says the letters should be written backwards.
'to' is a charade indicator (letters next to each other).
'country' becomes 'nation' (synonyms).
'me' reversed gives 'em'.
'em'+'a'+'nation'='EMANATION'
'takes' acts as a link.
Can you help me to learn more?
(Other definitions for emanation that I've seen before include "produce radioactive gas" , "Something given off" , "Something flowing out from a source" , "discharge" , "Issue" .)
