River of Sweden? (4)
I believe the answer is:
eden
'river of sweden?' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'river of sweden?' is the wordplay.
'EDEN' is hidden in amongst the letters.
However, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for eden that I've seen before include "Early garden - Cornish project" , "The original garden?" , "The perfect garden in need" , "Someone once seen in Number Ten's" , "prime minister in the past" .)
