Endmost journalist is cultivated (6)
I believe the answer is:
'cultivated' is the definition.
The answer and definition can be both to do with creating things as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
'endmost journalist' is the wordplay.
'endmost' becomes 'rear' (I've seen this in another clue).
'journalist' becomes 'ed' (short for editor).
'is' acts as a link.
Can you help me to learn more?
(Other definitions for reared that I've seen before include "Raised" , "Brought up, nurtured" , "upright" , "Trained" , "Provided and cared for during childhood" .)
