Concerned with the origins of writer Jean, I note (7)
I believe the answer is:
genetic
'concerned' is the definition.
Both the definition and answer are adjectives. Perhaps you can see an association between them that I can't see?
'with the origins of writer jean i note' is the wordplay.
'with' is a charade indicator (letters next to each other).
'the origins of writer jean' becomes 'genet' (I can't explain this - if you can you should believe this answer much more).
'note' becomes 'c' (musical note).
'genet' next to 'i' is 'geneti'.
'geneti'+'c'='GENETIC'
Can you help me to learn more?
(Other definitions for genetic that I've seen before include "Like type of code" , "relating to origin" , "Inherited; of origins" , "handed down through the generations" , "origin of something" .)
