Outcast one left in Somerset river (5)
I believe the answer is:
exile
This could be a double definition.
'outcast' is the first definition.
(I've seen this in another clue)
'one left in somerset river' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
Can you help me to learn more?
(Other definitions for exile that I've seen before include "Person forced to live abroad" , "officially banish" , "Person banished from the home country" , "Person absent from home or country" , "One lives away from the home country" .)
