It flows to the southwest in a Scandinavian country (4)
I believe the answer is:
eden
'it flows to the southwest in a scandinavian country' is the definition.
The definition suggests a singular noun which matches the answer.
'it flows' is the wordplay.
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'flows' becomes 'den' (I am not sure about this - if you are sure you should believe this answer much more).
'e'+'den'='EDEN'
Can you help me to learn more?
(Other definitions for eden that I've seen before include "happy state" , "Leading 11 [CONSERVATIVE]" , "Adam and Eve home" , "Foreign Secretary" , "Someone once seen in Number Ten's" .)
