Ended nice novel welcoming writer's impartiality (12)
I believe the answer is:
independence
'impartiality' is the definition.
(thesaurus)
'ended nice novel welcoming writer's' is the wordplay.
I cannot really understand how this works, but
'writer' could be 'pen' (I've seen this before) and 'pen' is found within the answer.
an anagram of 'ended' is 'ndede' which is present in the left over letters.
an anagram of 'nice' is 'ince' which is located in the remaining letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for independence that I've seen before include "State of relying only on oneself" , "Freedom from outside control" , "lack of bias" , "Self-reliance" , "Autonomy" .)
